Did some further checking. No radio interference causing it. I did notice that if I just rub my finger over the right stick while the heli is on the floor, with battery connected and radio on, with no throttle, the top blades move very quickly forward and back, as they are very sensitive to very slight touch of the stick. I than tried to hover it by really holding the stick without any movement, hard to do, and it flew without twitching.I also noticed that if you don't touch the right stick during a hover for that 1/2 second, before the CP Pro runs away, it doesn't twitch. So it seems to be me causing the problem because the radio lever is tooooo sensitive. How can we make it less sensitive??? Maybe the servo lever holes??? Any thoughts????
