the mini revo's esc is rated up to only 3s right? there's a youtube video
http://www.youtube.com/watch?v=sA3CL00dPT4 saying it does 59mph on 4s!!?!?! I think they confused the fact that since they put in 2 x 2s lipos they thought they were running 4s (if they were using a parallel connector) but i believe its a series connector...IDK....and if you run 4s on the mini ESC won't it fry?
