hi wanted to know if it would be safe to run rcm's new 30t pinion on a 47t spur in a buggy using a mmm 2200kv combo because i need to be able to beat a rustler with vxl combo on 3s in a drag races me on 4s? i am currently running 25/47 and i hit about 50?! another question is will i blow my esc??!? 4s or 6s?
