Designed for helicopter speed, this powerhouse of a motor can also pull over 7KW (160A) for a few seconds and 120A continuous

Scorpion HKII-4235-630Scorpion Motors are well known for their high quality highly rated motors and this new one, the HKII-4235-630, is specifically engineered and built for use in high speed racing applications. It’s the perfect match for speed machines such as the GAUI R5, which in the right hands is a 150MPH projectile. The motor can run at 7.1KW for 3 seconds, just enough to complete a 200M course at 150MPH, and it can run also continuously at over 5.3KW. Maximum continuous current is 120A so if your cells are holding up at 4V you’ll be over 5.7KW.

This little powerhouse is just 52.3mm (2.06″) diameter, with a body length of 64.5mm (2.54″) and is wound using 180 degC rated 1.6mm diameter wire. The motor weighs just 522gm (18.27 oz) and runs a bit faster than most in this class, so if you’re looking to push headspeed towards the 3000 rpm mark, this would probably be a good choice.
