The Futaba worked alright on everything but drift mode. In which case the throttle would go in out of being responsive. Hold full throttle might take off or might sit there. If it took off it might only go ten feet and stop. It might even go from a dead stop to full throttle at a whim.
I didn't care for the buzzing sound it makes when in various modes. Gives the impression something isn't correct like drift mode. Now to try to figure out how to get the Spektrum DX6R to work. Hopefully it'll be better.
Did you ever get it to work correctly in drift mode. Having the same issue with it hooked up to my 3PV. All other modes work fine.
