USA warehouse now open. Our USA warehouse is now open! Low cost shipping and an ever growing variety make ordering from the US warehouse even better value!
So I bought one and no you are not taking off the prop adapter. it is actually built as part of the bell housing. this is actually kind of a good thing because you will not be abe to bend this prop.
If you need crazy power for short duration, you can run this motor on 2S with the TGY 6A esc. However, do not push throttle beyond 60% for more than 5 seconds in case you fry the motor. This motor is rated at 4A max for 10s (see pic) instead of the 12A as printed.
I'd like to lathe off that chubby prop saver and change the shaft for a longer one to see how much fat can be shaved off. This motor would save me having to mod the HXT 5g motors to a higher kV for use on 1S set-ups in my peanut models. http://www.hobbyking.com/hobbyking/store/images/em_s mile.gif
Could the quest for the perfect little 1S motor at a decent price be over??? Just ordered one to test it. Crossing fingers I'll get it fast enough to test it before winter!
Please , HK should think to the customer preparing an order * I want buy this engine , I want to get the whole propulsion device achieved, BUT WHICH PROP FITS THIS ENGINE ??? which ESC I can't find the answer .So I don't buy it .
Just giving one prop and one ESC that could fits , would greatly help your customers , Sir HK .
Engine is made well, Prop holder is not removable. Hole on mounting plate (approx 3mm) is necessary for shaft. 4 starts for vibrations even if sticker was removed.

this motor does not produce the same amount of thrust as a parkzone/ eflite musyang motor. it draws more current and makes less thrust than the 8.5mm coreless, brushed mustang motor and gearbox. disappointing.

I was delighted when I opened this little motor. I love the backplate with mounts and wire protection built in. I also love the built in prop saver.
I spun it up with a fully charged 300mAh 1S battery on a HK 5A ESC and it didn't start but just jittered. With a hand start at 10pcnt throttle it started up but there was vibration. WOT without a prop was pulling almost 1A. WOT with a 4x2.5 was 2.5A. Sounds about right but the RPM was not there.
I tested continunity on the winds and it doesn't seem to have a short or a broken wire. Then I looked inside the bell and noticed a strange arrangement of magnets. The motor runs with a 9 pole stator and 12 magnets in the bell. Very common. The magnets were arranged in three groups of 4. In other words, four magnets aligned side by side, then a space, then 4 more, then another space... etc. I think this accounts for the poor efficiency. The magnets are glued into place (very common) but there was a puddle of dry glue on one side of the bell. That would account for the vibration.
I think this motor is better engineered than others in this size and weight, but the assembly needs some adjustments. Hopefully HK will improve future releases.

OK so the vibration is coming from the two screws in the prop adaptor, Take them out vibration goes away. I used 1 cell 160mah, 3A ESC, 4.5x3 prop. Im guessing based off the weight of my plane, 50g of thrust and 2.5-3A draw for a flight time of only 3 minutes. 4 crowns in quality only because of the prop adaptor screws. they need to be very carefully centered.

So this little motor is about 6.2g and does deliver on what it says as power, however this little motor is power hungry. I have been using this motor with a 1 cell 160mah 25c and a 4.5x3 prop. I get about 50g of thrust and a flight time of only 2 1/2 minutes if I run full throttle. Running full throttle, a 3a esc stays cool but the battery does warm up.
