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 has double ball bearings, has a replaceable 3mm shaft and can be mounted both in front of and behind the head frame/engine mount.
The weight-optimised high-end motor A20-6 XL EVO kv3500 with a weight of only 78g is ideally suited for 450 helicopters.
