I drove my XX-4 for the first time lastnight and I love it. I threw around the idea of selling it, but I took it to the track lastnight and man this things handles great. There were a couple guys that was watching me run it and was very impressed with it. I let one drive and he was wanting to buy it off me.
I had it geared to high at first and the GTB shut down on me. I put a smaller pinion on it and that thing just got even more crazy.
I'm hooked on some 4wd buggies now. Actually buggies in general. I ran my BK2 for the first time lastnight as well and loved it too.
