Hacker A20-12 XL Competition kv1039
The A20-Competition series was 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, which means that there are no rotating motor parts other than the motor shaft! In conjunction with the cable outlet at the rear, even the narrowest hulls can be safely motorised.
The weight-optimized high-end motor A20-12 XL Competition kv1039 with a weight of only 88g is ideal for glider models up to 1.4kg and motor and sports aircraft up to approx. 900g
