In Stock


The Scorpion S-5030-220KV motor was specifically developed for F3A electric pattern aircraft, and is designed to run on 10 Li-Po cells with props in the 19 to 22 inch range. Everything possible has been done on this motor to get the most power at the lightest weight. The Front housing, Bearing Tube and flux ring have been made as light as possible, and a Titanium Main Shaft is used to save even more weight while maintaining strength.

Scorpion Competition Series Brushless Motors are built from the best materials available, and are designed to provide both quality and performance at an affordable price. Scorpion starts with high quality aluminum alloy parts that are produced on the latest CNC milling machines. These parts are then gold Electro-Plated to provide a beautiful, long-lasting finish. The stators are made with 0.2mm laminations to give maximum efficiency, and minimum Eddy current losses. The stators are epoxy coated to prevent shorts, and are hand-wound with wire that is rated at 180 degrees C (356 F). The high temperature magnets used in Scorpion Motors are designed to give top performance in the most demanding applications.

The Scorpion S-5030-220 motors come with 4mm male Bullet style connectors already attached, and include a complete hardware package that contains the following: 3 matching female bullet connectors for your speed controller, 3 pieces of heat-shrink tubing, 1 prop thrust washer with tapered locking collet, 1 collet spacer, 1 prop front washer, a prop nut and a locking jam nut with a 4mm threaded spinner screw hole at the tip.

This motor is designed to be front mounted in the nose ring of an F3A pattern type model. By mounting the motor this way, the rotating mass of the motor sits behind the mount point, and the rotating mass of the prop is ahead of the mounting point so the two balance one another. This motor cannot be disassembled and have the shaft flipped to come out the other end.

Scorpion Motors are built to last, and are backed with a 2-Year warranty against defects in materials or workmanship. For the best overall combination of Quality, Performance, and Value, use a Scorpion Motor on your next model!
