the only radio transmitters, also called remote controllers, that embed a fpv screen, for seeing what the drone sees, near the joysticks, instead of having to get obstructed vision by goggles,
that I found, are :
- https://www.youtube.com/watch?v=df0Cvv3T69Y called fpv1 (i'm not interested into h7000 as it runs android and requires wifi rather than RC)
- https://www.youtube.com/watch?v=XBbptOuXXdA called fpv2
However they only seem to be able to bind Hubsan drones...
Would it exist a way to flash them in order to make them run openTX firmware, or anything that could make them become universal controllers?
Alternatively, what parts from Hubsan should I buy if I want to put in my own custom drone build and be compatible with the DIY ecosystem ?
Can I build from scratch a controller with arduinos so that I could use openTX, embed an fpv screen, while still getting decent range (>5km) ?
