Scorpion HK-2221-6 V2 Brushless Motor
Can I run the Scorpion HK-2221-6 with on 3 cell battery with the stock Align speed controller? What pinion would be ideal for this motor?

I think the 450M motor is one of those under appreciated little gems.
Awesome power and pretty easy in batteries

HK-2221-6, Kv = 4400, Pmax = 525W, Imax = 50 Amps
HK-2221-8, Kv = 3595, Pmax = 475W, Imax = 45 Amps
HK-2221-10, Kv = 3000, Pmax = 440W, Imax = 42 Amps
HK-2221-12, Kv = 2500, Pmax = 400W, Imax = 38 Amps
These motors are by far the most popular ones in the 22mm series. They are designed to provide the maximum performance in 400 to 480 size electric helicopters. Because these motors are so popular, we will spend a little more time here giving specific application notes on each one. In addition to use in Helicopters, the HK-2221 series are also used very successfully in Airplane applications such as Pylon Racers and Hot-Liners that require a high power, high RPM motor. More recently, they have also become very popular for powering 65 to 75mm ducted fan units that are capable of utilizing a motor that is 28mm in diameter. For the purpose of this article, we will stick to Helicopter applications.
For operation on 3 Li-Po cells, there are 3 different motors that can be used, the HK-2221-6, -8 and -10 models. The most versatile model is the HK-2221-8 motor. This motor can utilize a wide range of pinion gears, and this allows the motor to “Grow” with the pilot as their flight skills improve from beginner up through moderate 3D type flying. Here are some common applications of the HK-2221-8 motor. These numbers assume a main gear with 150 teeth, which is very common for the 450 size machines.

I actually just put a 450M motor in my FBL pro. I took out my -6 just to try a different motor. The 450M is easier on packs and has great power.Align I Team Futaba I Thunder Power I

I run the -6 in my Sport with the stock 35 amp esc no problem, 2200mah packs done in 3.5 mins so im not flying gently either. Align 35 amp ESC is rated at 45 amps for 15 seconds, 55 amps will be no problem for 2-3 second bursts (the bursts won't even be that long).

I had the 450M motor on 15T pinion (100% throttle) and get roughly the same headspeed with the -6 on 11T, still 3.5 mins. I was getting 4 mins with the stock 14T pinion.

In other words a cheaper upgrade would be a 15T pinion for the 450M. I still prefer the -6 though.

I have used the same motor (-6) in an EDF jet on 4s and a pusher prop jet on 3s pulling 105 amps at full throttle static! Bullet proof motor!!
60% of the time, it works every time!
