I created the JB Xilo Beginner Build kit to make it as easy as possible for you to build your first FPV freestyle quadcopter. I picked all the parts you’ll need so you know everything will be good quality and will work together. And I made a complete video tutorial taking you through every step of the build, all the way through the first test flight. This kit is available with both analog and DJI video system, depending on your budget.

Although the whole point of this kit is to learn to build it yourself, you might prefer to have GetFPV build a “bind-n-fly” version for you, so you can see how a pro would do it. There are links to both the DIY Kit and the Bind-n-Fly (BnF) version below.

The iFlight Evoque, Diatone Roma F5 V2, and GEPRC Mark 5 are all extremely closely matched in terms of performance and durability. Frankly, you won’t go wrong with any of them. They’ve all got very capable ESC, flight controller, and motors. They’re all available in either a DJI FPV version or an analog version. So let’s focus on the things that set them apart.

The Evoque has awesome LED light pipes on the side plates and bottoms of the arms. It’s got 20 mm-sized FC and ESC, which are usually less durable than 30mm-sized ones on the Diatone and GEPRC, although I haven’t heard any specific complaints about the Evoque blowing up ESC’s. If you buy the analog version of the Evoque, it’s got the weakest video transmitter, at 600 mW. That’s enough to get the job done, but the Diatone and GEPRC are stronger. I was most impressed with the Evoque’s flight characteristics, although all three were very good.

The Roma V2 is the lightest of the three. The V2 version fixed the “arm breaking” problem that the V1 had, but the arms are still relatively thin and may not be as durable as the other two. The analog version has a 1000 mW video transmitter. To me, the Roma is the budget option.

The GEPRC Mark 5 is, at the time of this writing, the most expensive. The frame is thoughtfully designed. It’s got a tough aluminum front end and a clever split top deck that allows maintenance without removing the HD camera mount. The GEPRC seems to me like the best option if you’re willing to pay a little bit more. The frame design is my favorite of the three. The analog version has a 1600 mW video transmitter, the highest of the bunch.

The “Vannystyle” is based on Alex Vanover’s signature frame. He’s known as one of the fastest racing pilots in the world, but he’s also an incredible freestyle pilot. The Vannystyle frame has 6mm arms for maximum durability and stiffness. The no-frills design of the quad keeps weight reasonable and makes for snappy, responsive flight. Alex’s motors have all the punch and power that a racing pilot would expect. The biggest objection some people will have to the Vannystyle is its price. It’s way more expensive than the Nazgul or the Roma, and its specs are similar, or in some cases worse (e.g. F4 processor vs. F7). This is because Vannystyle is hand-built by technicians in Orlando, Florida, with a custom PID tune designed by Vanover himself, and backed by Rotor Riot’s support. Some people will be willing to pay a premium for that; others won’t.

When iFlight released the Evoque, I assumed the Nazgul V2 would be discontinued. Which was a shame, because the Nazgul was such great price-per-performance value. So imagine my delight when they kept making it!

The Nazgul V2 is about $50 less than the Evoque. The motors are iFlight’s Xing-E budget line, which is still excellent. The FC and ESC are 30mm size instead of the Evoque’s 20mm, which is an upgrade as far as I’m concerned. And the video transmitter goes up to 800 mW — plenty! The frame is a bit bulkier than the Evoque, and it lacks the Evoque’s flashy light pipes. But I half-suspect that the arms of the Nazgul V2 are more durable than the Evoque because they don’t have a light-pipe channel down the middle.

In other words, the Nazgul is an incredibly solid 5″ freestyle quad at a really compelling price.

Oh right. It’s analog video only. DJI isn’t available in this model.

I fell in love with the QAV-S because of the genius way its arms join to the frame, allowing for one-screw arm changes, without putting a weakening screw hole through the center of the arm. It hits the sweet spot of being roomy enough to build with ease, without being so big that it compromises flight characteristics. It’s also relatively lightweight, but still tough enough for typical freestyle bashing. (If you are the hardest-core of concrete bando bashers, you might want a heavier frame.)

As much as I loved the QAV-S, there were a few things I changed to make the JB Edition. I requested a solid top plate for increased rigidity and strength; this also allowed the removal of one standoff. I shortened the standoffs to a 22m height. I thickened the front-bottom plate from 2mm to 3mm. Finally, I added a few notches to the tapered rear of the top plate, to allow a 2nd battery strap to be used without it sliding backward. All of these changes increased the frame’s strength and durability while keeping the overall weight below 115g, which I think is the sweet spot for great flight performance.

The QAV-S JB Edition also comes with a custom JB-branded sticker sheet if that helps make up your mind.

This frame will hold a Caddx Vista, but not a DJI Air Unit

AOS 5″ V2


The AOS5 was created by Chris Rosser, an Aerothermal Engineer who turned his professional expertise towards making the best-flying quadcopter frame ever. Chris used computer-based stress and resonance analysis to balance lightness and strength while pushing vibration frequencies above the range that the FC cares about. The result: clean, smooth-sounding motors, and the ability to turn filtering down and PID gains up for the sharpest flight response you’ve ever had.

All that aside, my favorite characteristic of the AOS-5 is its flexibility. It’s got multiple 20mm, 25mm, and 30mm mounting slots, so you can mount almost any hardware you want.

If this frame’s up-side is that it was designed by an engineer first and a pilot second, that’s also its downside. The frame is a bit fiddly to build and maintain, and it’s not as durable as some other frames. This isn’t just an issue for concrete bando bashers; even more “normal” pilots may find the balance too far in the direction of “lightweight agility” and not enough in the direction of “heavyweight durability”.

The ImpulseRC Apex is considered by some to be the best freestyle frame you can buy today. It’s tough as nails, and its reputation for having superior vibration characteristics was recently objectively confirmed by the aerospace materials engineer Chris Rosser.

Why doesn’t everyone fly the Apex? It’s heavier than some of the alternatives (although this does increase its durability). And it’s one of the most expensive 5” frames you can get.

This frame comes in 2 versions. The standard version will hold a Caddx Vista, but not a DJI Air Unit. The HD version is extended to fit a DJI Air Unit. The HD version does not have 20mm mounting holes in the back

Kabab FPV (Bob Roogi) re-defined racing frames with the Floss, finding ways to shave weight without compromising durability (too much). The Glide is his entry into the freestyle arena.

Freestyle pilots often focus so much on durability that they forget how much weight affects the way a quadcopter flies. Lighter quads are more nimble, accelerate better, and fly for longer than heavier ones. The Glide comes in under 100 grams! Compared to some other freestyle frames, that’s like saving half the weight of a whole GoPro Session!

The Glide is less durable than heavier frames, but it’s designed so that the easily-replaced arm breaks before anything more important. If it’s critical that you be able to fly home after every crash, the Glide may not be the frame for you. If you’re trying for a light build with just enough durability to keep you from tearing your hair out, the Glide is probably the best choice you can make today.

This frame will hold a Caddx Vista, but not a DJI Air Unit. Unless you flip the frame around front to back, mount the camera on the “rear”; mount a 20mm FC and ESC in the “rear”, and mount an Air Unit in the “front”. In which case technically you can jam an Air Unit into it.

The Source One is one of the best values in FPV frames. It’s community-designed and all the CAD files are open-source and available for anyone to manufacture. As a result, The Source One is one of the least expensive frames you can get and is available nearly everywhere. (You could even cut it yourself if you have a CNC machine!)

While the Source One will get the job done, it’s obviously been manufactured to a price. It’s a sparse and utilitarian frame, but if you’re on a tight budget, it’s a great choice (and no guilt over buying a “clone”).

The Siren gets a place on this list because of its versatility and well-thought-out design. It’s not perfect, but it’s got enough going for it that some people are going to love it. It can mount almost any video transmitter and camera you prefer, even large digital ones; and there are clever 3D prints to keep things clean and tidy (we love the dual capacitor mounts).

There are four versions of the Siren F5. The “standard” one has a single-piece bottom plate with 25mm height through the entire length of the frame. This version can fit up to 5.5” props, and those using 5” props will appreciate a little extra room between the body and the props (fewer chopped battery leads). The “split” version splits the bottom deck similar to frames like the QAV-S and the Apex. This means the middle and rear of the frame have shorter standoffs, for a more compact build. Both the “split” and the “standard” versions are also available in a “mini” version which has shorter arms and is lighter weight. The “mini” only fits up to 5.2” props, but otherwise shares the features of the larger version.

The “standard” Siren frames weigh around 105g, and the “mini” around 95g, which is extremely light for a freestyle frame. Lighter builds can be more nimble and fly longer. They have been carefully designed for stiffness and resonance, so they should fly well on default PIDs, and those who push PID tuning the limit will be able to get a lot more out of these frames. However, lightweight freestyle frames are not the most durable. If you fly hard and crash a lot (especially into concrete or asphalt), this may not be the frame for you.

Most complaints about the Siren frames center on durability. The standoff screws are M2 size, with a vibration-isolating “sock” over them to bring them up to the standard M3 diameter. M2 screws are much more likely to bend in a crash, and most FC and ESC already have vibration-isolating “gummies”, so many people would prefer this frame come with M3 stack screws. Unfortunately, this isn’t possible without modifying the frame.

The frames also don’t have mounting for 20mm FC/ESC. A larger 30mm ESC hangs out over the hourglass shape of the frame, and some users complained that this caused the ESC to take more hits and die sooner.

One of the biggest debates in FPV right now is whether beginners should choose 4S or 6S batteries. In my opinion, 6S has a small performance advantage, but it’s a bit more expensive and more likely to blow ESC’s when pushed hard. For five-inch freestyle, if you go with 4S, choose a motor between about 2300 kv and 2700kv. If you go with 6S, choose a motor between about 1600 and 1800 kv. Lower kv motors will make less power, but have longer flight time and be easier on the battery.


People kept telling me that I had to try this motor. I’d heard it all before. But they were right. The FPVCycle 25mm Imperial is a truly special and unique motor for freestyle. It’s powerful and punchy, sure. But where it really excels is low throttle response, such as when you dive down a building face and then need to quickly and smoothly stop your fall to hit a gap at the bottom of the building.

Kabab has kept the exact dimensions of the motor secret, but it’s rumored to be approximately 2506 in size. And somehow, the weight of the motor is only around 33 grams, the same as a typical 2306 motor.

This motor works great with almost any five-inch prop, but Kabab recommends a lower-pitch prop for maximum control. If you prefer the thrust and punch of a high-pitch prop, the motor can absolutely handle it. Whatever prop you choose, be sure to keep AUW low (Kabab recommends below 670g for best performance). If your AUW is closer to 750g, consider using a slightly larger battery (such as 1250 mAh 6S instead of 1100 mAh) to handle the amp draw.

Emax is seriously messing up the whole FPV motor market with their Eco II line. As far as I can tell, they are making a $22 motor and selling it for $12 just because they want to be taken seriously as a motor manufacturer. I have no idea what the actual motivation is, but the Eco II is a seriously great value. It even has premium EZO bearings (an area where other budget motors often skimp).

At the time of this writing, the Eco II comes in only three sizes: 2306 and 2207 ideal for 5″ or maybe 6″ props), and 2807 (ideal for 7″ props). For 5″ props, choose 1700kv for longer flight time on 6S batteries, 1900 kv for more power on 6S batteries, or 2400 kv for 4S batteries. For the 2807, choose 1300 kv for long-range cruising on 6S batteries, 1500 kv for a bit more power on 6S, and 1700 kv for 4S, or for 6S builds intended for aggressive freestyle.

If the Eco II is available in a size that you want, from a store that you want, it’s hard to argue that you should buy anything else. Nearly everything else in this price range is inferior. And motors that cost twice as much may be better, but are they twice as good? Especially if you’re just going to destroy them in a crash.

XING 2 2306

If the Emax Eco II line delivers $20 motor quality for $12, then the iFlight Xing line delivers $27 motor quality for $20. Everything about Xing motors is top of the line: single-piece curved bell in 7075 aluminum for maximum durability; center-slotted N52H curved magnets for maximum responsiveness; NSK bearings; titanium alloy shaft; and a proprietary o-ring between the bearing and the bell to help protect the bearing from impacts and smooth out vibrations.

The Xing2 is a great all-round choice for freestyle.

The NewBeeDrone Flow is another entry in the budget freestyle motor category. Newbeedrone regularly sells it in a “crazy deal” of eight motors, with a price working out to around $15 per motor. These are solid motors for $15 and should be considered as an alternative option to the Emax Eco. One catch: they ship from the USA only, so if you’re not American, the shipping price probably will rule them out.

The T-Motor F40 Pro line used to be clearly the best freestyle motor you could buy. But it’s hard to justify the price of this motor, given how good some of the competition is. iFlight motors are equal or better in quality; FPVCycle motors have superior performance; Emax motors are a better value. The F40 Pro IV is a top-notch motor, and at about 30 grams, it’s lighter than almost any other motor in this class. But you really have to want that T-Motor pedigree to bring yourself to pay what T-Motor is asking for this motor.

When I first saw this motor’s odd size, I thought it was just a marketing gimmick. 2207 is so played out! Let’s make a 2107! No wait! 2107.5! That’ll really stand out! But I was wrong. This motor is made by RCInpower, and they don’t play around when it comes to making great motors. So I went back and thought about the effect of a motor’s shape on its performance.

Wider motors have more surface area for better cooling. Taller motors are more responsive because their mass is closer to their axis of rotation. The volume of this motor is about the same as a 2207, but it’s narrower and taller. In other words, this is a slightly more responsive motor than a 2207, with slightly worse cooling.

And you know what? That’s actually a pretty good idea. Because freestyle pilots are seldom at full throttle for long periods of time, so the motors won’t tend to get very hot; and the additional responsiveness makes for better flight characteristics.

If you live somewhere with very hot temperatures, or if you spend a LOT of time at high throttle, then this isn’t the motor for you. If your current 2207 motors come down smoking, this isn’t the motor for you. But if you’re like most freestyle pilots, you should think about giving the RCInpower 2107.5 a try. (Or buy the GEPRC, which is basically the exact same motor, just with different branding.)

The flight controller (FC) is the brain of the quadcopter. It receives your commands from the receiver and translates that into motor outputs that make the quadcopter fly. Modern flight controllers may also include accessories like voltage regulators, an on-screen-display (OSD), a power-distribution-board (PDB), and more.

Flight controllers on this page may be marked as “DJI Ready” and “DJI Only”. DJI Ready means that the FC has a plug to allow easy connection of a DJI Air Unit or Caddx Vista. DJI Ready FCs can still be used with analog FPV systems. DJI Only means that the FC does not support analog video at all, and should only be used with the DJI System. Any FC not marked this way will support both analog and DJI, but if using DJI you’ll need to solder wires to the FC since it doesn’t have a plug.

If you use Walksnail or HDZero vTX, they also work with all of these FC. Instead of having a plug ready to go, you might need to solder some wires to the FC.



I’m pickier about flight controllers than almost any other part of a quad. That’s why I’m so thrilled that RaceDayQuads invited me to design the JBF7 from the ground up exactly how I wanted it. I started with big, easy to solder to pads. The pad layout focuses on flexibility and ease of use. There’s an SD card slot for all the blackbox logging you could want. Beefy 5v and 9v voltage regulators mean you can power modern, high-powered digital video transmitters or even a few LEDs. And a detailed user manual with wiring diagrams and instructions for getting started.

V2 of the JBF7 adds several much-requested features. Now the FC has a USB-C plug. It’s got an onboard barometer and (FINALLY!) you can run iNav on it if you want. There are status LEDs that let you easily confirm the function of the voltage inputs and outputs. You can switch the video transmitter power on and off using an aux switch on your controller. And we added plugs for all the major features if you prefer not to solder directly to the FC.

Like many FC today, the JBF7 has switched to the BMI270 gyro. Although this gyro can only run at 3.6 kHz (which is, I admit, less than 8 kHz), it has been tested to perform as well or better than the ICM gyros that were on the previous version of this board.

The Speedybee F405 stack might be the best value FC/ESC stack today. Start with the price. You get an FC and ESC together, for the price of most other FC alone. And the crazy thing is, you barely give up anything in terms of features, performance, and build quality. The layout and features of this “budget” FC are almost identical to Speedybee’s premium offering. They both have built-in Bluetooth for wireless configuration with the Speedybee phone app. They both have a built-in LED readout that shows whether your battery is charged or discharged. And despite the fact that this FC has an F405 processor, it’s got plenty of UARTs broken out for all your peripherals. It’s even got an SD card so you can log blackbox data for dayyyyyys. Because the F405 processor is slower, you may not be able to run Betaflight at the highest possible loop rate, but chances are, you’ll never notice the difference.

The ESC runs BLHeli_s firmware, not BLHeli32. That means you won’t be able to use features like bidirectional dshot or variable PWM frequency. Performance out of the box will be fine, and you can flash the BlueJay firmware to the ESC if you want to unlock those features.

Given how much I know the components on this FC must have cost, I don’t understand how Runcam manages to sell it at this price and still make a profit. When it first came out, I waited a few months to find out if there would be performance or durability issues. But so far, it seems to have passed the test. If you can find this FC in stock, it’s probably the best buy for the money.

The T-Motor F7 is a high-quality flight controller with all the features you might expect. But what really stands out in this combo is the F55A ESC. This is one of the most durable, reliable ESC’s you can buy today. I won’t go so far as to say it’s indestructible, but it’s about as close as you can get in this hobby.

Hobbywing has always made some of the most reliable ESC’s in the FPV market. Lately, they’ve started stepping up their FC game as well. This stack starts with a BLHeli32 ESC, so you’ll get all the latest features like variable PWM frequency and startup music. The 60-amp rating is far more than most will need, up to about 7″ props. It has a 12v regulator to power your video transmitter (whether analog or DJI), including an onboard pit switch, which allows you to switch the vTX off remotely if you want to power it up without interfering with your friends. It’s even got a built-in camera switcher, so you can view two different cameras (analog only) such as one forward and one rear or downward facing.

One drawback of this FC is its compact size. It’s designed with both 30mm and 20mm mounting holes. The 30mm holes are on break-off tabs. This means that the FC is basically 20mm in size, which severely limits the available space on the board. As a result, there are small and limited solder pads, and some resources are only available in plugs. This approach is confusing since the ESC has only 30mm mounting holes, so if you’re buying the FC and ESC together, you’ll never use the 20mm holes.

Despite this quirk, the Hobbywing Xrotor Micro F7 is a great FC at a decent price, paired with an exceptionally good ESC.

Aikon has made some of the strongest, most durable ESC’s on the market for years. It’s no surprise that their 20mm Aikon Pro ESC is one of the few that can stand up to the abuse of FPV racing. The Aikon flight controller has an F7 processor with plenty of UARTs for peripherals. It’s got a built-in 10v regulator to power DJI (if you choose to race on DJI, this is your pick) or your analog vTX. It’s even got a built-in pit switch to let you power down your vTX with an aux switch. The main downside of this FC is that the solder pads are very small, but that’s sort of true for all 20mm FC so maybe it doesn’t matter.

Find this product at these vendors:


This is the FC if you want something inexpensive that will get the job done. What’s it give up to get the price down? It’s only got four UARTs instead of five; it’s only got a 5v regulator, so your vTX needs to run on 5v if you want the cleanest video possible, and it doesn’t have a plug for a DJI FPV video transmitter (but you can still direct-solder if you prefer).

This FC now comes in two versions: a standard and pro version. The difference is the pro version has a “real-pit” function that can completely power down the vTX when you’re not using it. The pro version also has more solder pads, but as a tradeoff, it hangs out past the standoffs slightly compared to the standard version.

I recommend pairing this FC with the Foxeer Reaper ESC. The Reaper has been tested and proven by racers since it was released, and it’s extremely durable, especially for its price.

If you look closely at this flight controller, you might guess that it’s actually made by Aikon and sold under T-Motor’s branding. The layout is very similar and the features are nearly identical. No matter who makes it, T-Motor has a great reputation for quality and performance. But mostly, I’m including it as an alternative in case the Aikon is out of stock. It’s also the FC used by Evan Turner (HeadsUpFPV) in his race builds as of this writing.

50A V2 20X20 ESC

Unlike the other entries, this one is going to start with the ESC, not the FC. Redux Air makes what might be the toughest, highest-performance 20mm ESC available today. It uses the same larger, higher-rated FETs used on 30mm ESC’s. And somehow, they managed to shrink it down from its predecessor so it’s about the same size as other 20mm ESC! In my opinion, this is one of the best 20mm ESC’s you can buy today. If you can find it in stock.

This ESC can be paired with almost any FC, but you will probably have to re-arrange the order of the wires in the harness connecting them together.

Every FPV aircraft has a camera and a video transmitter to send the camera feedback to the pilot. Which camera and video transmitter you choose depends on which video system you’re using. Video systems are divided into two categories–digital and analog–and we have a page with recommendations for both.

If you’re using a digital video system (DJI, Walksnail, or HDZero), CLICK HERE.

If you’re using an analog video system for freestyle or cruising, CLICK HERE.

And if you’re still not sure which is best for you, here’s a video to help you decide:


Batteries for 5” freestyle will almost always be 6S or 4S voltage. 6S offers slightly better performance especially towards the end of the pack, where it seems to feel like it has less voltage sag. (Be careful, as it’s easy to over-discharge 6S packs by not realizing they’re about to die.) 4S is slightly less expensive and less likely to fry ESC’s. Most pilots today are flying 6S, so if you’re on the fence, that’s probably the way to go.

All of the packs listed above give good performance at a reasonable price. Choose the smaller packs if you want a lighter, more agile quad, with a slightly shorter flight time; choose the larger packs if you prioritize flight time over handling.


Tattu R-Line is some of the best batteries you can get. And the price reflects it. Given the chances of destroying a battery in a crash, you really have to ask yourself whether the additional performance of a premium battery is worth the price. Personally, I run budget packs and I’m happy with them, but if you want the absolute best performance, or if you’re very weight-sensitive, you won’t go wrong with the R-Line 4.0.

T-MOTOR 4943 & AXIS 4943.5


Everybody seems to want MORE all the time. These props answer the question: what if LESS is better? These props are 4.9″ in diameter, which means yes, they make a little less thrust than a 5″ or 5.1″ prop. But they are significantly lighter, and that means they’re more responsive and smoother in flight. The reduction in thrust also improves throttle resolution at the expense of top-end power. These props are particularly suited to very light 5″ builds (under 650 grams) which can feel floaty on larger props. They’re also great if you’re running just a little higher kv than is ideal.

I always thought these props were overrated until I tried them on Mr. Steele’s actual quad. Then I got it. These props are terrible on heavier freestyle builds. That’s not what they’re made for. But on lightweight freestyle builds (5″ quads under 650 grams All Up Weight) they come alive.

Have you ever dove over an obstacle and then needed to catch yourself precisely at the bottom to fly through a gap? That’s where these props excel. You can find the exact throttle position you need quickly and precisely, without over-shooting or pulsing the throttle. They’re also easy on the battery for extended flight time. The tradeoff is that they lack the razor-sharp cornering and neck-snapping acceleration you get with higher-pitch props.

These props are best when used with a wider motor like a 2306. When used with a 2207 or 2208 motor, the taller stator’s non-linear throttle curve doesn’t fit as well with the Ethix props’ low-throttle linearity and precision.

Steele recommends the S3 for quads between 500-650g, up to about 3000′ above sea level. The S4 gives a little more thrust, especially suited for altitudes up to 10,000′. The S5 has the highest pitch and is for heavier quads up to 750g (such as carrying a GoPro). The S5 is also 18% gray to make it less visible if it’s in the camera’s view.

The Gemfan 51477 is the perfect prop to pair with larger motors like 2407 and 2208, or even bigger!

Many freestyle pilots today are moving to larger motors, which allows the use of heavier props without compromising handling. This gives the best of both worlds: punch, speed, and smoothness. But only if the motor is paired with the right prop. A light prop doesn’t demand the torque that the bigger motors put out, and it doesn’t make enough thrust to counteract its weight. Too heavy a prop drives amp-draw through the roof, shortening flight times and killing batteries.

The Gemfan Hurricane 51477 hits the sweet spot between those extremes. It’s got enough pitch to make the most of the motors’ torque, without going overboard like the 51499 might. And its unique blade profile gives reasonably good control even at low throttle (something high-pitch props are often bad at.)

Of course, I also love to run these props on smaller motors like 2207 and 2306. It makes great power, but the reduced torque of the motor means the prop isn’t as smooth and responsive as it is on larger motors.

GEMFAN HURRICANE 51466 / 51499


I first came to love the Hurricane 51499 prop when I was searching for the best prop for my JB2407 motor. Because my quad was heavier, it was loose and imprecise in corners. The 51499 has razor-sharp handling in corners and plenty of speed in the straights.

Although the Hurricane line was designed for racing, I like them for freestyle. They are not as smooth and controllable in the low end as some pilots would prefer. This is a great prop for somebody who wants to punch the throttle and get slammed back in their seat.

The Hurricanes are also designed to be durable. The hub is reinforced so that, after a crash, you can just bend them back and keep flying. This is advertised as making them suitable for racers, but I know freestyle pilots will appreciate it just as much.

If you have big, torquey motors and you want the most thrust and sharpest handling, choose the 51499 size. But you’ll need really healthy batteries or a really lightweight quad in order to keep your flight time up. The 51466 version is slightly easier on the battery and may be a better choice for smaller motors, or higher-kv motors.

The F3S and F4S are Gemfan’s latest generation of freestyle props. They’re 5.1″ in diameter, which lets them use a lower pitch without giving up thrust. The lower pitch helps with smoothness that freestyle pilots value and improves efficiency, but can make ultra-light builds feel too floaty. Like all freestyle props, they’re designed with durability in mind, so you can (hopefully) fly back home after a crash.

Pick the F3 if you’re using higher kv motors and/or value smoothness, predictability, and responsiveness over top-end power. Pick the F4 if you have lower kv motors and need more thrust, or if you just want a little more power.

Everybody knows that putting a capacitor on your build gives cleaner video and helps protect your ESC and other electronics from damaging voltage spikes. But capacitors can only do so much, and big, sharp spikes can still get through. Enter the TVS diode. A TVS diode chops the top off of voltage spikes, almost no matter how big they are.

So why don’t people use TVS diodes more often? Two reasons. First, you can usually get away without one. Capacitors do an ok job most of the time. Second, the specs for a TVS diode are a little more difficult to interpret than a capacitor’s, so it can be difficult to be sure you bought the right one.

That’s where this product comes in. The FPVCycle cap/diode system combines a capacitor and some TVS diodes into a single unit with pre-soldered wires. Just solder it to your ESC power pads and know you’re as protected as you can be from voltage spikes and electrical noise.

First, read the description of the FPVCycle cap/diode set, so you understand what a TVS diode is and why you need one.

The FETTEC spike absorber is just the TVS diode part of that, without the capacitor. Don’t go thinking you can omit the capacitor though! You’ve just got to provide your own. And you’ve got to solder on your own wires, while the FPVCycle one comes pre-soldered. And the FETTEC spike absorber is nearly the same price as the FPVCycle one. Just about the only thing the FETTEC product has over the FPVCycle is that it’s got three diodes, while the FPVCycle has two. Does that matter? I don’t actually know.

Bottom line: get the FPVCycle one if you can, but if it’s not available, the FETTEC is a fine alternative.

The Rush power filter board includes a capacitor and TVS diodes, similar to the FPVCycle product. The main difference between them is the form factor. The Rush board is designed to be soldered underneath or on top of the XT60 pads of a Rush ESC. This clearly isn’t going to work for every ESC and every frame, but nothing’s stopping you from soldering wires to the Rush board and mounting it wherever is convenient. It’s definitely bigger than the alternatives though, and some builds will struggle to find a great place to mount it.

Until recently, most GPS receivers used on hobby drones had an M8 chip in them. The newer M10 chip in these GPS units can lock on to four of the global navigation networks at the same time. That means more available satellites overhead, faster lock time, and more satellites locked for more precise position data while in flight. In short, the M10 chipset is just better than the M8, and you should use it if at all possible.

Flywoo makes three units. The Nano is ultra-small and light, but its tiny antenna will make it perform a little worse. The Mini is the same size as the popular BN-220. The Pro has the largest antenna and is the only one with a built-in compass (magnetometer). All of them have battery-backup flash memory, which means their programming can be customized using the U-center application.

One note: Betaflight versions 4.4.1 and earlier have a bug where the FC does not properly configure the GPS for optimal performance. If you are using BF 4.4.1 or newer, you should manually configure the GPS parameters using the instructions in this iFlight blog post. The default GPS configuration may cause poor return-to-home performance and even premature disarms.

MATEK M8Q-5883

The GPS M8Q is one of the best-performing, full-featured GPS units you can put on a quadcopter. It’s got a built-in, low-noise voltage regulator, RF filter, and low-noise amplifier means the GPS unit gets the cleanest possible signals. Translation: you can lock more satellites, faster. It’s got a built-in compass as well as a GPS unit. And the included wire harness has high-quality silicone insulation, not the cheap plastic insulation used by most other GPS units.

High-performing GPS units tend to be large. Which means most GPS units on small drones don’t perform very well. The iFlight M8Q is one of the best-performing tiny GPS units you can buy. It’s got a built in compass, as well as a low-noise amplifier for stronger GPS signal.

The BN-220 is probably the least expensive GPS unit you can buy. And its performance reflects it. In a perfectly clean environment, it performs well. But drones are not perfectly clean environments. They have a ton of electrical noise! Which means the BN-220 will often take forever to lock satellites, and when it does, it may not lock as many as you’d prefer. Frankly, there are a few people who think the BN-220 is not worth buying, but if you want to try to get into GPS assisted flight while spending the absolute least money possible, this is the one to get.

Let’s say you crash your quad somewhere and can’t find it. What do you do? Try to “home in” on the video signal? Beep the beeper? Maybe even arm the quad and listen for the sound of the props thrashing around in the brush. But none of that will help if your battery ejected in the crash and your quad is powered down.

That’s where the ViFly Finder comes in. It’s a super loud (up to 105 dB!) beeper with a tiny 1S lipo cell connected to it. A short while after the quad loses power, it begins beeping, and it doesn’t stop until you find it and disable it (or until the battery runs down). The Finder also acts as a normal beeper that you can activate with a switch on your controller whenever you want.

There are two versions of the Finder: the Mini and the Normal. The Mini is about 3g and its battery lasts about 7 hours. The Normal is about 5g and its battery lasts about 30 hours. In addition, the Normal has a light sensor that turns off the beeper at night. This avoids annoying your neighbors and wasting battery during time when you might not be looking for the quad.
