The A20-LN series has been specially developed for glider models with narrow fuselages. Since the fuselage becomes significantly thicker a few centimeters after the motor frame, a small torsional outrunner can be used in the direct drive. This small weight-optimized high-end engine with a weight of 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 sports aircraft up to approx. 1.0Kg take-off weight when it gets tight under the hood.
