80 mph on the stock sliders is very impressive. I tore up a stock one with the VXL and 3s, and have gone to MIP CVDs. Seems real smooth and straight but it ate the planetaries today at the track. Most annoying.
I decided not to do the big power mm/medusa thing because I wanted to keep it reliable and not have it break parts. No point if it's going to do it even with the VXL.
