In many cases, a toothpick will use a flight controller with a built-in video transmitter to save weight and simplify the build. If the vTX isn’t built into your FC you’ll need to add one. This typically leads to a slightly heavier and more difficult build but if the VTX ever fails you won’t need to replace the entire AIO.
The Ant Lite Nano is generally considered to be the best of the lightweight analog cameras and is available with and without mounting holes depending on what canopy you’re mounting it in.
The TBS Pro32 Nano is the premiere micro-sized vTX available today at only 15x13mm in size and weighing only a single gram. But it outputs up to 500 mW! It’s got all the features that make the TBS Unify line a favorite of FPV pilots who want the best and aren’t afraid to pay a little more for it. You can even change settings by putting a QR code in front of the camera (patent pending)!
It’d be easy to rest on the reputation of the Unify and say it’s hands-down the best. Nobody would argue. Except for Ahren Ciotti, the primary maintainer of this page. He’s had and has seen a bunch of dead Pro32 Nanos and has had better luck with the Eachine Nano, you decide.
