I noticed something today while replacing a blade grip after a small crash.The servo behind the main motor will ,while slowly spinning up,The arm on the servo will move down a little bit befor any of the other servos move.Could this be the reason way while in a hover I am constantly fighting to keep the heli from moving forward?Does it need to be replaced?
Also I had ordered some retaining pins and they seem to be of a smaller OD.What do you all do to keep the pin from sliding out?



Thanks All
