A guy on RCG has the Robird on a Trex 500. I had asked him what servo ball distance it calls for. He said his is around 18.5mm. That works for me because a T500 servo balls have to be run on the inside of the arms..and that in turn makes them contact the servo housing on full sweep. I moved my balls out on mine (with the ZYX) and had to turn the cyclic gain way down. He said the Robird will tell you if you have enough travel, if not you move the balls out. That works in my favor I guess. He said also make sure to have a full 12+/12- pitch range before messing with 0/center stick. Did you notice this as well?
