Great Performance

Jan 09, 2017

Actually its impressive Quality and Performance, i use it on my custom 3D-printing airplane, proppler 11x7, 3S battery, 20A ESC and it great choice for this combination, flow smoothly and accurate on the design, but there's no technical data sheet for this item which take from me time tinkering the thing

am planning to grape couple of them for my next quad-copter testing.

I bought 6 motors for my hexa.
4 of 6 motors came without the shaft adapter and without the black disc.
This is realy annoying.
Does anyone know where to buy this as spare parts?

i order 6 of this motors, one came spoil and the set screw can't lock down the motor shaft, so i use it on a 800 size quad instead.
AUW weight is 3kg with 4s 5000mah spinning 14x5.5 props.
flying time is 8mins of hovering with motor a little warm, pretty much thrust.
i try 12x4 props too, flying time is 7 mins with motors running cool.
i guess my quad is too heavy with 4s10000mah at 3.6kg

Be aware that the following statement is highly exagerated:
"Rated Watts: 1000W @ 18.5V, 800W @ 14.8V"
The wires are AWG20 and are getting warm even at 5A.
I tested the motor with a 14x4.5 propeller and 5S battery and this is what I found:
100g thrust - 0.70A
700g thrust - 5.00A (about 50pcnt throttle)

Unfortunately, the ball bearings are not top quality and looks like they are prone to failures.

Have 4 of them and love them. I fly them in an warbird with 1200g on 6s 2700 mAh with an 11x6 Prop. Flying time is near 8:30 Minute on full power, with so much vertical climb.... wowe. On the ground I have at full throttel 381 Watt in Power

This is my first brushless motor so I don't have any reference to others but I got first test prop and these results:

Turnigy PLUSH 30A ESC, GWS 10x6 3blade, with 12,7V 10A 930g thrust.

I think the wires going to motor are quit thin compared to adverticed amps and voltages, at least they are much thinner than wires coming out of PLUSH 30A controller.

just did my attempt at a duration test with my quad, flying weight was 1.42kg with a 5000mAh 4s and 12X6epp props at the end of the flight the motors where cold and 20A esc's where normal warmth total was 23.5minutes seems pretty good to me?
as for overall motor quality they seem to be pretty good, 3 of the 4 i have are great. one of them you can a few magnets in the can arnt quite in the same plain as the rest and the end wrapping before the leads leave the motor are pretty loose, im just hoping it never crashes down on that arm because a stick would snag a piece of magnet wire pretty easy. but that is mainly cosmetic i guess.
if anyone has questions about them il try to anwser but i dont have any thrust testing rig so i cant give that info but i will post the max flying weight i can achieve with this quad soon
