Well impressed with my setup now. I've left advanced timing on 10, moved up a couple more teeth, and I reckon i'm hitting between 45-50 mph. Certainly slightly faster than my vxl setup on 2s. Motor temp' hasn't gone over 120F and esc is cooler.
Rear tires are completely worn now though, so it's immobilized until new arrive. Also unable to fit any larger pinion as the motor wont move any further back.
I'm VERY happy that I didn't order an ezRun and paid a tiny bit extra for this combo.
