The EcoPower "Sling Shot SLV" 13.5 Turn Sensored Brushless Motor offers competition ready performance, at a sport motor price! The "Sling Shot SLV" takes everything that makes the standard Sling Shot great, but improves on the original with a heavily vented, lightweight can to help reduce overall weight and improve heat dissipation. Also, the "SLV" has larger solder tabs to reduce resistance and help make it easier when soldering the wires on. This creates a motor that delivers improved overall performance, with the power you need to out run the competition.

Other features include a high torque 12.5mm sintered Neodymium rotor to deliver the torque needed for competitive 13.5 class racing. When combined with its hand wound, high purity copper stator you get a low resistance 13.5 motor that will stand toe to toe with anything else on the market. Fully adjustable timing lets you fine tune the power delivery to suit your driving style and track conditions, while dual sensor ports allow easy installation in a variety of chassis configurations. These parts have been combined to deliver high end power, efficiency and reliability. Keep your competition in the crosshairs - take aim and fire with the Sling Shot.

EcoPower "Sling Shot SLV" Sensored Brushless Motor (13.5T)
Wrote a review earlier when I bought one of these motors and at first I thought these were great but I do have to say that these loose power very quickly and lack the torque like some of my other motors. These could use a little work if they want to compete with some of the other brands out there.

Took a chance with this budget priced motor. Running in Tekno EB410 4wd buggy. Has plenty of power and no fade after extended practice time. Buying and extra for back up.

I am very happy with this motor, I have been running it in a stadium truck at my local hobby shop carpet racing and this has plenty of power and stays cool with a fan. I can keep up with all the guys running much more expensive 13.5's.
