I've just received this motor, and it came with two 3mm shafts. Although description of this item was wrong it's OK for me, because 10T 3.17mm pinions are out of stock :-)

Great motor, better than some of the eflite motors I have used in the past. Shaft is kind of hard to take out.

I've been putting this off because I hate to leave a less than stellar review on hobbyking but here's what I experienced with this motor. First look, I received two 3.17 mm Shafts rather than both sizes advertised. This is fine since its the shaft I needed. Next, they were airplane shafts, net Heli shafts, the groove for the c clip was cut at the bottom instead of 2/3 of the way up so it was not possible to put a clip on. I planned on using this on a pusher jet so I needed to reverse the shaft, this required supporting the can with a piece of 1/8" pipe and heating the can with a torch before beating it out with a punch. Once all this was done I learned that the motor can't handle much heat. Burned out in ~90 seconds in flight with a 6x4 prop on a 3s battery. Went ahead and reinsulated the stator and wound it up with some RadioShack magnet coil wire to a slightly lower kv value and tried again. Same result. I'll keep it around, maybe rewind to original spec (mine arrived as 8 turns delta with six strand 28awg) and put it on my hbk3.

If you have money for to expend, you have to buy this motor. I recieve one of this, and the CNC motor head is deformed, Why Hobbyking not inspect the items of his customers?

Purchased 2 of these motors.

They are great for there size but I would NOT recommend them for a 450 class heli.

Even with a 9 tooth pinion gear the motor still gets hot after 30 second flight. ESC also getting hot.

Put a meter on the motor and it is drawing 38A on the 450 with a 10 tooth pinion.
