I have this glitch problem with this cp pro.Everytime i hover it will start jumping.Its not a sticky collective because it will do it with the stick dead still and sometimes when i power down it will spin back up on its own.Can someone put me back on the right track.The only thing i replaced when the problem started was the main brushed motor.I have the stock radio and the antenna is wrapped around the landing gear.Can it be in the 3 in 1 ??? Im lost and about to sell this thing.
