Tower Pro is a familiar name among electric fliers looking for a straightforward outrunner to power a park flyer or light sport model. This category is set aside for the Tower Pro motors carried here.
Outrunner Design
Outrunner motors spin their outer case around the windings, which produces the higher torque at lower rpm that direct-drive propeller setups favor. The Tower Pro 2408-21T is an outrunner in this class, with its size reflected in the 2408 designation and its winding noted by the 21T turn count.
Matching a motor to your model means weighing the airframe weight, the propeller you plan to swing, and the battery and speed control you will pair with it. A motor sized correctly for the job runs cooler and lasts longer than one pushed past its comfortable range. Reading the motor's own ratings before a first flight helps avoid overloading it on the initial setup.
See the current Tower Pro listing below for details and specifications.
