Working well with Hobbywing 40A ESCs.

They are NOT working with Afro 20A 2-6s Lipo out of the box.

Very good motor! Used with a 6S 4000mah battery and a T-motor 12x5.5 prop. The quad is about 2.3kg and has plenty of power! With gimball i get 14-15 minutes of flying! Here is a video: https://www . youtube . com/watch?v=qyrWGN_rUsA

Very powerful, mechanically good. Using 4225 motors on 700mm hexacopter with 6S Lipo and 13 inch props. Motors are not on its limits, still cold after 15 minutes of flight. Same for 12 inch props.

Wow! These come in their own little tin box. My mind is spinning with all the possible applications for the box. Oh, and the motors not bad either - I like the extra long leads. Bearings are good and solid, so are the leads into the motor. These are a solid well made unit.

very cool running motors, no heat at all, producing a lot of thrust in conbination with 17x5.8 or 17x5.5 propellers.

I like the sound of these brushless motors, will buy them again. They come with over(!) 35cm wires, so no problem leading them trough the tubes of multicopter having enough wire left to connect to outside ESCs.

Mechanically this is a good motor for the money.
Unfortunately there is no data sheet for thrust over revolutions.

I did my own measurements with a 6S lipo and 12" CFK-prop:

50pcnt throttle - 3.5 amps - 600g thrust - 3200 rpm
100pcnt throttle - 6.8 amps - 910g thrust - 3880 rpm

This motor is at it's limit on 6S and can operate max. 12" props.
On 4S it can handle up to 15" props (reported by international customers).

Seem to be smooth and balanced.
I've been trying to run these with 15x5.5 props on a 6S system, and the ESC's (ZTW 30A Spiders) keep losing sync and the quad falls down.
Still testing...
