Fast shipping! Received all my difficult to locate parts quickly. Super impressed. Thanks!

great

It was fast and easy!

Poor description of the product. The listing implies that i would be receiving the motors and the controller. After purchasing i realized the last number listed was for the motors only. Still a decent deal so I'm not too upset. Just disappointed.

Good
