RE: blade msr throttle cut off problem
It is a 5 in 1 problem. I crashed mine awhile back and damaged my tail rotor motor. My heli started doing weird things like you decsribed and it was because the tail motor was shorting out my 5 in 1. The end cap came of and it did not line up the right when I tried to put it back on. Once I replaced the tail boom/motor, my heli returned to normal. Now I am not saying that is your problem, just saying your problem is in your 5 in 1.
