good motor. I use it to power my big quadcopter. It works well with the afro esc 30A and a 4s 5000mah LiPo!
They have enough power but next time I probably would buy a bigger one... :)

has bought four engines before and they work perfectly.

Dom These engines are really bad in the solder, and the cable was broken by just where the 3.5mm connector is soldered. Metal wires are not of the best quality copper.

breaks off, at minimum load. very bad Hobby King. improve the era of quality assurance.

Awful motors. I fitted these to my Talon Tri with 10x4.5SF props. I under-mounted them and fitted the prop to the shaft using a HK 3mm collet-type adapter. First thing I noticed was the shaft/bearings had some play in them, but they ran smooth so I thought I'd try them anyway.
It hovered ok but as soon as I gave it full throttle there was a bang, then another as my tri hit the floor. The shaft had snapped on the rear motor. It seems a 3mm shaft simply isn't up to dealing with a prop that will take advantage of the motors (300w) power.
On closer inspection I found the bearings had gone in the other two motors, too. Plus the E-clip had worked off on one of them. This is after 2 mins air time!
On top of that.. these aren't 28-30 motors. That is the measurement of the OUTER CASING not the stator.
Overall, very disappointing.
