Ok just did DeWalt motor mod and works great, tons of power, very good fit, problem is its SLOW AS HECK, now im running 14/62 because of the lack of 5mm pinion selection at my LHS. So Im gonna order up some pinions and spurs but would like to know what would be the best setup for speed, 18/54? Im running both twin 7 cell 8000 mah nimh also 2S 25c 4000 mah lipos when not running in wet conditions, stock wheels and tires. Thanks
