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.
Q80-4L V2 kv270 is a professional Hacker Q80 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 hacker q80, 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.
Q80-4L V2 kv270 Product description and features The Q80-8M V2 kv180 for large scale heli models from 16 to approx. 24 kg as an alternative to a turbine. The prop driver with 30mm bolt circle and 4 x M5 screws transfers the high torque of the Q80 perfectly to the propeller. The motor has excellent efficiency and offers maximum power and top performance. Every Q80 motor is wound, assembled and extensively tested by hand. Quality “Made in Germany” for the highest demands. Ideal for large scale hel
