You could definitely set up a big block .21 in a Rustler chassis and it'd really be the only thing helping you achieve the speed you need to beat a brushless or atleast a 3.3..
Brushless are ridiculously fast they can achieve 70+mph like nothing, but so can you with the right engine, tranny and spur gear set up. I've gotten my Rustler to go 65mph my goal is 70mph
Absolutely! I made this tragic mistake when I raced my buggy and truggy! Had the fastest engines I could afford, great electronics but was beat every time by more skilled drivers. Should've saved that money and practiced more!
