For many years modelers had to choose from two ends of the power system spectrum:  Cheap motors made with inferior quality components or top-quality motors, made from the best materials, but with a price tag that was out of reach for many pilots.  The Tempest line of Brushless Motors provides the best of both worlds, giving high power output at an affordable price that will not break the bank!

Unlike most other motors available today, that provide virtually no performance information, Tempest motors include full Performance Data charts. These charts use actual testing data, from a motor testing dyno, measured at multiple input voltages using dozens of different propellers, so you know exactly what performance to expect for your model.

Also available for every Tempest motor is a full range of replacement parts including Prop Adapters, Cross Mounts, Shaft Kits and Bearing Sets.


Included with every Tempest 17mm series motor is a complete accessory kit that includes the following items:

  • Aluminum Cross Mount with mounting screws
  • Prop-Saver Prop Adapter with 2 O-rings
  • Threaded Prop Adapter with mounting screws
  • Machined Aluminum Prop Washer
  • Standard Hex Prop Nut
  • Machined Aluminum Spinner Cone Prop Nut
  • Hex wrenches to fit the crossmount and prop adapter screws
