A tiny little bit of play in the bearings but runs OK. With a 3S 2200mah pack I get 7000rpm on an APC13x4E at 14A. It would be great if the published prop data had rpm figures included.

Of the qty 7 I've got now, one came with the prop adapter holes without threads (was drilled oversize can't even fix it). Qty 3 have super rough bearings that need replacement before first flight. Qty 1 has a wicked wobble.

QC on these motors are a joke. Don't waste money on these.

These motors are awesome.
Using them on 450 and 550 mm size Quad-copters, they are very well made, smooth, quiet and powerful. Running 8" and 10" props they never run hot and the machined prop nuts look great when installed.
I would definitely recommend these motors.

These are very good motors, look well made and feel very solid.

Used them in 450 and 550 sized Quads and they have plenty of power with 8-10 inch props and are very smooth when running.

Will definitely buy more.

First Multi Rotor so not sure what to compare to but bought six of these. Doesn't seem to be a vibration issue but at least one motor started giving problems within about half an hour of flight time. Soon found it when the aircraft suddenly started tipping over at random. Noticed now that the bearings in that motor are very noisy.

DON'T RUN THESE ON 4S. 2 out of the 3 motors I bought for my tricopter could not take the 4s and would shut down midflight causing a crash each time. I couldn't figure out what was going on until I tried a 3s lipo. Switching to 3s eliminated the problem.
I saw smoke coming from one motor while on 4s, landed and unplugged...the motor is still working so they are built tough, just not made for 4s. Otherwise, good buy.
FYI the motors come with nothing, not even mounting screws.
