I just bought a hitec hs82mg, my lhs was out of hs85mg's and after installing it, I realized that it turns rather well on one side but only turns about the quarter of the way on the other side. this is happening every second or theird time i turn and is very annoying. also the servo gets SUPER hot after only 5 minutes of running. Is there anything i can buy to fix this problem? P.S. i have the 2.4 ghz radio.
