I have an exo terra.... Ive got an sc8 2s-4s capable esc with a ezrun 2700kv motor. How ever its not water proof(i dont think)
The traxxas velineon system is water proof its motor I belive is 3500kv I wanna say 3s capable but u may waant to double check. Ive got two batteries one is a bias 3s 5000mah 25c lipo the other is a 2s venom 5000mah, I use a racers edge charger. It charges 1-3s at 1,2,3,5amp its been good to me so far.
While its an awesome car that handles very very well imo the rool cage is annoying and the motor mount is not my favorite im on my 3rd and ive had it for 2 months. Granted the first mount broke due to ovee tightening but axial has since redone the motor mount and over tightening is no longer a problem, the second broke bcuz I looked away for a second and smacked a curb at about 30mph.
