A20-12 XL-LN EVO kv1039
A20-12 XL-LN EVO kv1039
Product description and features
The A20-LN series was specially developed for gliders with narrow fuselages. Since the fuselage is significantly thicker a few centimeters after the motor bulkhead, a compact high-torque outrunner can be used in the direct drive.
This small weight-optimized high-end motor with a weight of only 90g (3.2 oz.) is often used in glider models up to 1.5 kg (3.3 lbs.) Of course, the A20-12 XL-LN EVO kv1039 also fits perfectly in motor and sports aircraft up to approx. 1 Kg (2.2 lbs.) take-off weight when it gets tight under the hood.
Accessories
Suitable controllers and propellers can be found in the “Accessories” tab.
