Also one other thing... if you say you have quite a bit of flight time, have you ever changed the main motor? They only last up to about 20 flight hours, or about 60 to 80 flights on the conservative side. you might try replacing it and see if your problem goes away
I was having the same problem, the guy at HeliHobby told me that main motors will last about a year or so...
