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 anodized 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 wound with wire that is rated at 180 degrees C (356 F). The magnets used in Scorpion Motors are N-50EH style, which are rated for operation at 200 degrees C (392 F), making a motor that is virtually impossible to burn up in normal use.

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, give Scorpion Motors a try!

All of the Scorpion brushless motors are built with angled cooling holes in the front housing that create a built-in fan.  The airflow generated by these holes is sufficient to cool the motor core during use.

Rm = 0.0241 Ohms
Io = 2.395 amps @ 10.5 volts
Kv = 3595
Weight = 76 grams, 2.68 ounces

Great motor... lots og power.. no bog March 1, 2008
Reviewer: Kraig S from Sonora, CA United States  
This motor has a lot of power. I went from a 430L to this motor and couldn't believe the difference. Night and day. Also noticed that when I really fly it hard I'm using less of the battery, battery seems cooler, and the motor is totally cool. Very efficient motor. And the low price doesn't hurt either.
Now I'm just waiting for the new Scorpion to go in my T-Rex 500.

HK2221-8 V2 Scorpion major improvement over 430XL February 1, 2008
Reviewer: Blue from CA, United States  
With my poor collective management, I fly around basically at (close to) full pitch all the time which caused the 430XL motor to bog badly on loops, etc. I had moderate settings to ease the load on the 430XL(12T, 10 degrees pitch, 7 cyclic) - but would still bog when I combined maneuvers at high speed. Since the 430XL is not considered to be the weak point of the 450SE V2, I did not consider replacing it. After seeing the  reviews, I decided to give it a try. Yes, I read about how the -6 version is really the hot one (hard on batteries too), so I was not expecting a huge improvement. Well, after a half dozen flights today, it subjectively feels like the HK2221-8 has about 30% greater power than the 430XL with the same flight times. Anyone that has made the investment in the 450SE V2, should spend the 55.00 and try this motor - it makes the 450 feel like a little rocket and no bogging! Amazing output for a 70 gram motor and always runs super cool.

The scoprion motor -8 January 27, 2008
Reviewer: Jason  Chow from La Crescenta , CA United States  
I really like this particular motor on my trex 450. It's not mainhub bending fast  and has just the right amount of torque for smooth 3d action. Pair it with the scoprion esc and you have one killer combo!

Pretty good... but pain to install October 16, 2007
Reviewer: Mike S from Shippensburg, PA United States  
This motor seems to work quite well bog is almost gone. My problem with this motor is that it doesn't come with the right screws to mount it in the Trex motor mount plate. Because the entire motor physically spins instead of being in a "can" you must route the wires away from the vicinity of the motor, which is hard because the wires come out the top and get in the way of the motor mount plate.

The motor comes in a really nice package and includes three female gold plated bullet connectors. the motor leads already have the male ends attached.

I have limited use the motor as of yet but it sounds great and seems quite powerful.
