The A20-LN series has been specially developed for glider models with narrow fuselages. Since the fuselage becomes significantly wider a few centimeters after the motor mount, a small diameter outrunner can be used in direct drive. This small, weight-optimized high-end motor, weighing only 90 g, is often used in glider models up to 1.5 kg.
The A20-12 XL-LN EVO kv1039 also fits perfectly in motor and sport aircraft up to approx. 1.0 kg take-off weight when things get tight under the cowling.
