cx2 problem

[Wolffman]

I am very new to flying this helicopter. The 4 in 1 went bad. I replaced it. Now the lower blade will only run for 15 seconds, then it quits spinning. Everything else seems to work fine.

Might want to try posting your question in one of the heli sections of this forum. Probably get some faster answers. Good luck!

Hmmm... How did your other 4-in-1 go bad? One thing to consider is that motor being bad, or is there binding in the lower rotor system?

Another thing to consider is the yaw adjustment. Perhaps it's set too far one way or the other in the new 4-in-1. I don't have the instructions in front of me, so I wouldn't know how to start, but you can read up on it and see how to adjust it.

Beyond that, I don't know. Hopefully someone smarter will come along with a clear answer.

Good luck!
