I just bought a new ArcuCopter with 3DR APM 2.5. I have a quetion with Radio Control because I chose the model WFT09 Radio Control System (http://www.canadadrones.com/WFT09-Radio-Control-System-p/wft090-rad...) with FrSky More DFT/D8R-II Telemetry Combo Rx / T seems a good choice.
I would like to know if my Spektrum DX5 radio control would have on APM 2.5. How it works? Is it possible to take one of the following controller DX7s Spektrum AR8000 7 CH Transmitter with (https://store.diydrones.com/product_p/rc-spektrum-dx7-01.htm) Spektrum DX8 8CH or Transmitter (https://store.diydrones.com/product_p/rc-spektrum-dx8-02.htm) with flight APM2.5 Controller. Given the amount of investment and the compatibility of radio control helicopters with my other, I should have taken a Spektrum to be in the same DSMX modulation. In the case that I can change, is that I need a receiver. In both models presented, which would be the best fit for my model?
