My LMH Model 110 has been acting up lately. I flew a few days ago and it flew fine but i got no power. Then i looked at the manual and it said change the copper washers, if u have 15% nitro put in to and i had four so i took out to and tried to fly again this time everytime i started it the engine started but then when i pushed up on the throttle the engine died. Im using a Vmaxx 6. Plus when i charge up my radio it never goes up full, i am using a Hitec 6. So whats the problem with all of this?
