How to match an electric motor to an RC aircraft
A practical guide to motor KV, voltage, current, thrust, aircraft weight and flight style so the power system matches the model.
A40-10S V4G kv1600 + 6,7:1 PG is a professional A40-8-Pole mit Getriebe item from Hacker Motor GmbH, prepared for the RC-MODEL catalog with customer-facing information, official product imagery, structured specifications and no storefront supplier pricing.
This product is relevant for RC builders and pilots looking for a40-8-pole mit getriebe, replacement parts, upgrades or setup components. Use it when planning a new model build, maintaining an existing aircraft, boat or radio system, or comparing compatible electronic and power-system parts.
Confirm the physical dimensions, weight, voltage, current rating, connector style, shaft size, cell count, propeller range and installation space against your model. RC-MODEL can help verify compatibility when you provide the model name and part number.
A40-10S V4G kv1600 + 6,7:1 PG Product description and features This A40 gear drive is equipped with the 8-pole version of the A40-S motor, which has proven itself thousands of times over. The high-torque, high-speed external rotor in combination with the efficient 6.7:1 planetary gearbox has been specially developed for larger electric gliders up to approx. 8 kg take-off weight. Thanks to the perfect coordination of motor and gearbox, this power pack can drive propellers up to 23 inches efficien
