Holey Mackrel. I just threw a Mamba max and that old 2770kv motor I had no idea on what brand it was on it and on 3 cell it is slam nasty. You can be 3/4 throttle going about wide open and give it full throttle and it will stand straight up. Even in the wet grass. I just got it all put together about an hour ago and its dark now so I didnt get to play with it much. Its to dark. Ill have some pics and maybe a vid tomorrow.
