I have the no reverse mod done and am wondering if it's o.k. to run two batteries in series? Or will it fry something on the curcuit board? Thanks for any help, Mike.
we cant use reverse at are races its like with larger scale its all foward so we dont miss it,and besides if your running around a track in reverse please dont hit me! lol so it only makes since to get rid of it and go twice as fast
