About FrSky TFR4

Hi there,

I am a beginner in designing quadcopter. I want to ask, if I plan to control a quadcopter with NAVIO2 as a flight controller using Mission Planner, do I still have to use FrSky TFR4? Can anyone explain the function of FrSky TFR4? Thank you for the help.

Not the best choice according to bottom note on the user manual. You should prefer a more than 8 channels sBus capable receiver.

oh thanks, so what should I use to control the quadcopter using mission planner?

If you can control your quadcopter with mission planner (telemetry radio) you still need a RC set (Tx and Rx) for tuning of your quadcopter and safety of the flight.

TFR4 can do the job at minimum cost and performance.
