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.
A20-34 S EVO kv1500 is a professional A20 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 a20, 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.
A20-34 S EVO kv1500 Product description and features The 8, 10 and 14-pole outrunner motors of the A20 series are available in 4 lengths (S, M, L, XL), with a voltage range of 7.2V to 12.6V. As a result, they cover a wide range of applications from the 250g indoor model up to the 1.5kg electric glider. The A20 series is double ball bearing mounted, has an interchangeable 3mm shaft and can be front or back mounted. The weight-optimised high-end motor A20-34 S EVO kv1500 with a weight of only 29g
