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.
A30-18 M kv2900 + 6,7:1 is a professional A30 with gearbox 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 a30 with gearbox, 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.
A30-18 M kv2900 + 6,7:1 Product description and features The compact, lightweight gearbox drive consists of the high-torque A30-M and our highly efficient 6.7:1 planetary gearbox. This makes the use of larger more efficient and quieter propellers possible. Propellers up to 18 inches can be driven by this power dwarf. For use this only 196g light engine in the classes F3B, F3J and F5J, but of course can also be used in similar models and scale gliders. The takeoff weight is usually between 2.0 an
