K, Thanx. Also I have been having a little problem. I did the long shaft hop up, and the lower rotor mounts that screws into the outer shaft doesn't hold position on the little holes. (sorry if my terminology is bad, I am a newbie) Are those screws supposed to screw into the outer shaft? doesn't seem like it. If I had to guess, it is just to locate the screws, but they aren't able to be tight enough. Essentially, what happens is the bottom rotor doesn't spin, and I get no lift. Suggestions?
