Dear all, I just switch my batt from nimh to 2s lipo, running on 9.5t lrp brushless with novak gtb spectrum. I'm getting some kind of clacking at full throttle, but when i accelerate gradually, the clacking sound disappears. Does anyone knows how to solve this problem? I tried changing the front and rear diff bevels, but no avail. Running on 2s 40c lipo.
