Hacker A20-22L EVO

The A20 motors are small outrunners with excellent efficiency at minimal weight. Of course, these A20 motors also use efficient neodymium magnets adapted to their radius.

The A20 motors come with a rich accessory set including spare shafts, motor mounts for rear wall mounting, prop adapters, and the necessary screws!

The 2008 EVO version impresses with its low weight, improved cooling, even higher temperature stability, and new bearing shield.

With the A20-22L EVO and 3S LiPo battery, gliders up to 1100g, sport and scale models up to 800g, and even 3D aerobatic models up to 550g are well motorized.
