I got one for powering my futur Tiger Moth 1400mm laser kit which would weigh 2,5 to 2,8 kg. I will have do take care of the thrust lever ! Read the following:
On the test bench with the HK LightElectric wood prop 13x6", I got peaks of 3kg and then constant 2,8kg of thrust @ 750 to 700W and ~ 52A.
For a 15€ setup, I guess even the devil cannot do better...
Next test onboard, when the Tiger will be built...

This motor is powerful. I used it to test a 2.7kg 60in Yak-55, the 2.3kg HK Estrella, and I had a magnet failure yesterday testing props on a 2.6kg HK Space Walker, easy fix, I'll buy another one. The HK Estrella flys so well with this motor, that I left one in there, and never bothered to get a fancy motor for it. Just get one, (or two) !

I bought this motor as a backup in case my 5055 was held up in transport, just so I could test fly my new 60" Yak 55, but I wasn't sure it would pull it into the air. I fitted it with a 15"x8" prop and it pulled the 2.7kg Yak up unlimited vertical ! I just wonder what this motor will do on my 42" Pitts Python :)

Very solid build/construction of this motor, I've bought it for a 1.4mtr plane, time will tell it's durability, I will re-report on this motor after a few months of flying with it.

for 13 bucks you cannot beat it over 10 pounds of thrust on a 4 cell and a 14 inch prop..and around 800 watts. only have a few hours on it but so far so good ..defiantly not top shelf quality but for the price its great for a heavy lifter

Excellent motor I am now running two, both drive 13x6.5 APC props using a 60A SS Esc.

One is pulling a scratch 4.7lb, 1/4 scale Vans RV-9 around with great authority, and 12 min flight times.

Quiet, pwerfull and robust. Perfect HK !

Perfekter Motor fr den Robbe AirTrainer 140.

Baugleich mit dem Orginal der allerdings 39,- kostet.

I am not sure these bushes are self oiling. My motor seizes up every now and then. I then pull it apart and oil it and it works again for a while.

Heres the thing, i am running these on a 4s with a 11" slow fly prop on an octo, these motors heat up big time, hot enough that some of high heat glue from my hot glue gun melted.
And i was at 50pcnt throttle most of the time, not goot at all.
Thos cheap bell type brushless outrunners that are blue and say 3s max, i rand those on a 4s with 12" props, they get slightly warm, are half the weight, half the size and cheaper, they also give the same thrust pretty much, this donkey motors are just rubbish

800 watts on 4s no problem, but bushings wear fairly quickly, still usable but slight vibrations due to wear.
