Francois TX - Rating: 4 of 5 Stars! Verified Owner Thursday, August 30, 2012
My car, Losi SCTE totaly stock. Outdoor track clay and very very large, location Texas so actual temp 100. Gearing 16x40 and too hot... 15x40 and fan on motor, temp around 160. ESC is great and run under 125, motor has some temp issue so I have to gear down and Top speed is not crazy ( a little bit more could be great) For the price and perf, it was almost 5 stars but for me brakes are not enough so It will be 4 stars. This combo works very well in my car and I m sure on a lighter car it will be amaizing.
