The idea is to take an old FM transmitter and replace it with modern electronics to make a usable every day TX for quadcopter use. When done it will have roughly the same capability as a Taranis with:
- ER9X/OpenTx
- USB
- Voice
- Haptic Motor
- Telemetry
- (backlit LCD except I probably won’t use it for retrofit)
