The Jumper T18 has many of the same features as the RadioMaster TX16S described above. This is because the founder of RadioMaster used to work for Jumper, but then split off to make his own company.
So why would you pick the T18 over the TX16S, especially because the T18 is more expensive? The T18 has built-in support for 900 MHz control. This has the potential to give tens of kilometers of range. In short: for normal use, forget about failsafes. However, people with a bit more budget are probably going to prefer TBS Crossfire for 900 MHz control, because it’s much more refined, tested, and reliable. Those people won’t put much value in the T18’s support for 900 MHz.
The T18 has good performance when used with 900 MHz receivers, but its 2.4 GHz range is a little worse than the RadioMaster or FrSky radios. This is because it has an internal 2.4 GHz antenna, to make room for the external 900 MHz antenna. The internal antenna is directional, so it is more sensitive to the orientation of the controller than the external antenna on most radios.
The Basic model of the T18 has Hall Effect gimbals, similar to the T16. The Pro model has Alps RDC90 gimbals, which are higher quality.
The T18 has a 480×272 IPS screen, without touch screen capability. In the future, Jumper plans to release an 800×480 touch screen, once OpenTX supports it. This will be a hardware upgrade, whereas the T16 comes with the touch screen pre-installed, and will only require a software upgrade to enable it.
