I'm gonna be running 2wd electric buggy for starters. That's mainly what I ran even though I've tried just about all of them at one point or another. Never got into nitro though, it was never that big when I used to race. Just toys for bashing around in the yard or parking lot at the time. I can't believe how big it is now. I had a 1/8 OFNA 4wd a long time ago and it was awesome. I'll be bringing out a 2wd electric truck I had way back when for my daughter to beat up on in practice though.
