The EcoPower "Sling Shot SLV" 17.5 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 17.5 class racing. When combined with its hand wound, high purity copper stator you get a low resistance 17.5 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 (17.5T)
For the money this motor is great, it has probably 98% of the power of the brand new 150 dollar motors for 60 bucks. There are 1 or 2 guys that creep up on me in the straights but not by much, I have room to add a little gearing probably too my temparatures have been under 130 after a 5 min race so far. So if you are on a budget I definitely recommend this motor.

The motor is powerful, but has cogging issues and the sensor wire went bad. BTW, eco power is an amain brand. That's a really good thing.
