I put the frsky rx's in my extra and see a slight stepping motion on the faster servos, not bad but it is there. these are hi speed hi torque digis (180 oz in, .13 sec at 6v) this is on a 9c wich is known to be a slower unit anyhow. There is no noticable stepping with the 72mghtz 149 pcm recievers. I think that this caused from switching from pcm to ppm tested the it with a 127 ppm rx and the same stepping is apparent.
