Im running a mmp 2400kv on 2.8 trenchers and due to the width and spacing of the wheels (using front offset)I think I may need a stronger servo. I feel like sometimes when its moving about 15-20 mph on grass and I turn sharp the wheels dont physically turn as much as I would like, when going slower or braking everything is OK. Anyone have experience with something that will just drop in and give me what Im looking for, waterproof would be nice.
