I bought a used summit vxl a couple months ago. Came stock except for a 100a hw esc. I took it out and put the stock vxl3m back in. On stock gearing, this thing is fun! Perfect basher. I tried gearing up with a 23 tooth pinion. But ended up back at stock. It was faster, but temps went up and I just liked the way it squats and tears it up stock. The only problem I had so far was the driveshafts kept breaking. I put the stock merv driveshafts in..and problem solved. So for all you folks that are thinking about getting one, stop thinking and do it! Just thought i'd share how cool I think these little trucks are.
