No matter the price tag is way over priced , the main reason, is they sponsor a lot of guys, sponsor a lot of events, advertise a lot, and not being open source, very expensive to do the programming , also when these companies develop there own cpu , that is also expensive,
The latest from FrSky, not to be confused with FlSky, not the same, has all the top quality pots , switches, gimbals are hall effect with full ball bearings. The operating cpu is an ARM 32 if memory serves, is also used in US cruise misles for its solid performance, but more important, they don't tell you how to program your radio, its a clean sheet of paper like the old Multiplex MC 4000, This lates one Tray radio is made of aluminum, it has 16 channels or 32 with a second module, the others don't have anything remotely close, full telemetry, with a bullet proof reciever ,
They don't sponsor anyone or any event, its open source, you can use your computer to program it if you wish, and they don't advertise, and all this for a price tag of around $300 including a 6 channel reciever, with full telemetry and sbus to get full 16 channels
