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.
C54-2Y XL Acro 6.7:1 Competition Kv 1115 is a professional Acro version (Motor Planes & F3A) 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 acro version (motor planes & f3a), 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.
