Very smooth system! Runs cool, easy to set up (especially with pro gauge) and the price is right. I'm running this with 14 tooth pinion in losi scte and its wicked fast. Most guys wouldn't run this high of kv in a 4wd short course but I figured why not? Now I can run on the local 8th scale track if I want or just use the pro gauge to lower the throttle end point to run on smaller tracks. Viper did well with the vx4r, it includes the double sided foam tape for the speed control and switch, and the esc wires are just long enough to reach the receiver box on my scte in a neat fashion (under battery tray). |
