RE: Radio question
The Futaba 9C is a very good radio and has all the mixing functions you could need, the only thing the 9C can not do that the 9zap, 10,12 and 14 can is move butterfly mixing off the throttle stick, other than that the 9C is a bargin at the moment with quite a heavy discount if you look around because it will be discontinued very shortly, one other plus point is its freqency module so that changing to a 2.4Ghz Futaba or Spektrum module can be done when you feel the need to change.
I have both the DX7 Spektrum and a Zap with a Spektrum module, if the Futaba module had been available when I bought them I would have gone Futaba a I feel the facility to hop channels is better than having two channels only, this is IMO and is not knocking Spektrum in any way.
