The A20-Competition series has been specially developed for narrow hulls. They are lightweight, powerful, encapsulated external rotor motors with high torque and efficiency. They do not require a gearbox and are suitable for a wide range of applications. The A20 Competition motors are completely encapsulated, so there are no rotating motor parts except the motor shaft! In conjunction with the rear cable outlet, even the narrowest hulls can be safely motorized. The internal fan, double ball bearings and interchangeable 5mm shaft make the motor efficient and robust.

The weight-optimized high-end engine A20-22 L Competition kv924 with a weight of only 81g is ideal for glider models up to 1.4kg and motor and sports aircraft up to approx. 900g.
