I ordered 4 of these for a Crossfire 2 quadcopter. As another review says, the lack of screws was kind of annoying. These motors look beautiful on the quadcopter, have a lot of power and are easy to install once you get the M2.5 screws. I'm not sure about the price, maybe cheaper motors perform just as well, but I haven't tested anything else so I can't really comment on that.

Have received my 4 engines today, and two were having problems with unglued magnet and two magnet brokens... Have to repair them without having seen them turn ! That's not a good way to have a good feeling... Please take care of that HK !!!
Engine bigger than attended but feel ok. Bearing seems tiny for such a big engine and 12' props, I have to take care of that. ESC to be soldered and tests to comes.

I desperately need shafts and prop adapters for these. The ones that come with the motor are pretty fragile. I wish Hobby King would tell us which ones to buy. Or better yet, have an accessory kit for this motor.

The propsavers that come with these are made from soft aluminium and are absolute rubbish. Two of them have snapped within two days, so now I can't fly at all.

Bonjour, Je voudrais savoir si vous pensez que je peux utiliser ce moteur avec du 5S (18,5 volts) ? Par ailleurs est-ce que ce moteur peut entraner des hlices en 14"

Very fragile, I wished the made it a bit heavier, and more robust. Well Balanced, but bad Bearings, need to be replaced soon. some run noisy out of the box. Shafts are quite soft, bend on any ground Contact.

Spare Shafts would be URGENTLY needet.

Also a good Motor for a FPV Pusher as it runs very smoothly. No good for Planes where the Prop easily touches the Ground, here this Motor wont make you happy. I use it on 4s with GWS 3Blade 1065 Props

Optical nice Motor good Magnets and electrical Data, but the Motorhousing is poor and rapidly bend.
the Bearings and the Shaft to small for 12" or 13" Propellers.

For $31 you would think they could have included some screws. Being M2.5 not M3, they are not exactly a common size.
