An LRK (outrunner) brushless motor for R/C aircraft up to 3.5 kg powered by 7-12 cells or 2-4S LiPo; suitable for cabin models, scale models, aerobatic models and gliders - this is quite a hot motor and would work well in competition gliders - it is a suitable competitor for the Hyperion 3025-6 competition motor - use the 110A speed controller if you are going to push this motor. No gearbox is required because of the high torque of this motor type.

All Scorpion 30mm motors have 3 ball bearings to support the rotating housing.

The S30 series of motors from Scorpion all have 30mm diameter stators - there are 12 stator arms and 14 magnets in the rotor housing. The stator is 26mm long in this 3026 version. The motor wind is a 5 turn delta wind with 26 strand 0.25mm wire.
