I was wondering what kind of brushless systems people use in the prerunner, and what sort of modifications would be necessary? I know that a 2s lipo is a must. I have heard about a hobbywing combo, and I've seen that the Castle Sidewinder Micro 2 looks like the kind of thing that would fit, and maybe even a VXL3M combo? It would mainly be motor size that would be my concern.
Thanks for any help!
