The 'mini' savage is still a decent sized car, it runs on 1/10th scale electronics, while its theoretically a 1/12th. It uses a 4000kv 4 pole 540 motor, and is phenomenally fast on 3s. People have been having ESC breakdown issues, a lot on 3s, but stillla couple on 2s. It seems the Sidewinder Sv2 is being asked to do rather a lot, still, those who have had no problems say the car is astonishing. It sure seems virtually indestructible in soe of the vids I've seen. There's a big discussion going on about it in the mini forum, check it out, many pages of info.
