Traxxas TRX-4 FJ40 with TRAXX

Bought a set of Traxxas TRAXX for my TRX-4 FJ40(Defender) chassis, back in the summertime, and actually got to try them out before Christmas! Low elevations in Western WA rarely get snow, so I was happy to run them in my backyard. I was figuring that I would eventually have to drive in to the mountains to get to some snowy spots.
Traxxas recommends only running the TRAXX in low gear(on a 2-speed chassis), but I'm sure it's because the electronics can't handle the load. It's way too slow for my preference, so I will likely upgrade to a brushless setup. Going downhill in 2nd gear was much more enjoyable!
