Copilot with digital servos and JR PCM 9X

Recommended Posts

Hi there! I would like to buy a FMA Copilot to assist my heli flight training. I've heard that some controllers of the JR series may need the buffer. I'm using JR PAM 9x with DS811 digital servos. Does anyone know whether I need that buffer or not?? In addition, do you know any webshop that ships overseas (As I live in Hong Kong I need a shop that ships to here).

If possible can somebody giving a brief comment on that thing? Is it really so magical that once I relieve the control it will be able to hover the heli in the mid air??

Thanks bud.

Co-pilot, it works great and should help immensely with training. Yes, if set up correctly it can return the helicopter to a very nice stable hover. As far as buffers I would get them to be on the safe side, I have seen problems with both JR and Futaba with the co-pilots and other autonomous gear like the PDC 10 and 20.
