It's up and running again. Got a few packs through it, and so far so good. I just went with a New Era tower, and tweaked things some, and it seems to be working. I put a Xerun 80a combo in it, and it seems to be a good system. I need some lower gearing to run it on 4s, but surprisingly it does good on 2s, geared 16/54. I also threw an old Revo body on it, and some truggy tires.
