Probably after looking at ur vid i'd say reduce weight, like also not using 2 buwizz, and decrease bodywork. Personally mine is powered by 1 buwizz and 2 buggy motors, but i saved a lot on the weight, mine weights about 475 grams. So i dont know if 4 will be better but i'll try uploading the final project like in a month once me and my friends/team are done with all the development of the whole car. Also do you have any suggestions for steering systems, as i use a servo and the 7 stud rack, and really thin wheels to minimize friction. Thx
