I have two of the KD A22-20L motors in sailplanes. They work great.

10x6 folding prop, 230watts, 20amps with a 3s 1800 Lipo
9x7 folding prop, 191watts with a 3s 1300 lipo

These motors are excellent! I can't rate it any higher. They are very powerfull for their size and fits anything up to a 15 size plane. On a 10e airobatic (Extra 300) it puts out about 250w using 3s LiPo and 10x5 prop and pulls the plane vertical. I have no hessitation in recommending this motor above all others. Flight times are about the 8 minute time on a 2200mAh battery and only using 60pcnt of the battery capacity.

I love this motor and will buy, at least, two more once they are available.

11.5 volts, 10X6" folding prop, 9550 RPM, 235watts, 21.4 amps, calculated thrust of 1.2 kilograms.

I suspect that I'm a bit conservative on the thrust calculation because it takes my 800gram Specter straight up as high as I want it for thermaling in 10-12 seconds and is still accelerating at the top of the climb. 40-50 flights so far.

I love this motor! I have it in a Specter 1800 that weighs 800grams. With a 9.5X8 prop it will accelerate indefinitely at 70-80 degrees. It gets as high as I want it in 9-12 seconds. I will definitely pick up another as soon as they are in stock just to have on hand for any future projects.

Not entirely satisfied with this motor.

It looks nice but it is poorly isolated, it is extremely magnetic, you can hang a hammer from the bell just by magnetic attachment.

I paired this with a plush 25A ESC and did not get the thrust i was expecting, i had to replace this motor on the plane it was intended for.

The worst thing is the quality! At the third landing I did, the prop touched the grass but did not break, instead the motor ripped out all the threads in the mounting holes. After re-threading the holes i tried the motor on another plane but at the landing this time three of the magnets came loose!
This motor just gives me too much trouble, I recommend you to by a turnigy motor instead...

Die Motore, die ich erhalten habe sind schlechte Qualitt, von drei Motoren luft keiner. Beim bewegen der Anschlsse, zucken sie manchmal.
