I’ve had it for a year now and stop using it because the driveshaft is bent. It needs a new driveshaft in order to work, but there has been major upgrades to it. The motor is upgraded. The battery is upgraded and the controller is upgraded as well as some brackets and tires. Tires need to be replaced. Motor is a ezrun 4268 2500kv sensored motor. The controller is also $300. I just need to get rid of it and this is a really good deal.
