Well, update, my plastic pinion finally went, this was at 3 am this morning, fresh snow, had to think of something, ended up putting the slipper system off my rustler onto the WK tranny. It actually just slipped on, no mods! I now have gearing choices! I'll have to get video tomaro. I had so much fun today, i did a few front flips, haha. It actually climbs good, i can go up a near vertical snowbank for a good 2 feet and get over a 10 ft bank :D
