Looking at this for a small quadcopter. Nice to see the shaft can be replaced. Would like to know what length was used so I can order from HK with the motors. Bigger question is if the mounting base is removable. The base is too large for the arms but perhaps the motor can be mounted directly.

I need to replace the shaft with something a few mm longer. I've taken the motor apart with no difficulty, but... how do I safely remove the shaft from the rotor? Do I just support the hub well, and tap it out with a small punch? My application is geared, so normally, I would need to support both ends of the shaft (maybe a 9mm ID bearing over the prop saver hub.) But this little gem is so beautifully narrow that I may be able to skip the bell end entirely if I can extend a shaft out the mount side... Until I get my gear train built, I've been benching it mounted to a chunk of 2x6 framing lumber* with a 2s20c Turnigy Lipo and 8x4 wood IC prop, it screams and lifts the chunk of wood menacingly. Very impressive little motor!

Hi. Could anybody answer what size of connectors included with this motor? The link to this connectors on this site would be better :) Thanks.

Alot of flyers just solder wires directly to ESC and use heat-shrink tubing.Saves weight.

Hi. I have just received this motor but there is a grinding sound on it. I couldn't stop the sound although I lubricated the bearings and tightened the screws. Here is a short video: http://www.youtube.com/watch?v=821p9ograCQ

I HAVE RECEIVED MINE - IT SOUNDS SAME AS YOURS.

AND IT HAS A BROKEN PHASE - STARTS LIKE MIXING ROCKS.

IF U TOUCH THE ROTOR IT WON'T START AT ALL.

IT WILL BE ''ROCKING''
 Maciej 33 points
YESTERDAY I RECEIVED ANOTHER ONE.

IT IF BROKEN AS EXACTLY THE SAME WAY AS THE FIRST ONE.

THIS IS JOKE HK.

R THEY BROKEN MADE OR WHAT?

ANOTHER ENGINE I GOT - 2822 - 1600 kV ROTOR IS BAND - GOOD FOR VIBRATOR.

I opened the motor, removed the bearings. But I realized that I don't have the same bearings and I bought them. I hope I can solve the problem in this way. But I think the problem is caused from the gap between the magnets and the stator.
 genisis1 18 points
had a simmilar problem it is caused by to much current in the motor on startup the way i solved the problem was tochange startup mode on the speed control to soft start and all problems go away good little motor!!!!
 JelleB 478 points
*Macej: if it will start, then you do not have any broken phases, you probably need to adjust your esc timing or startup. And your Caps-Lock key, it is stuck?
 roberted5 104 points
HK is copying the best motor made.The most costly motor made.
It'll take a while for them to get it right.
Winding looks horrible can it be rewound?

*maciej Maybe. SHEKO comes from Egypt everytime you order sth and destroys it hahaha!

Can anyone really comment on the comparison with the 2402. Is this one really that much more powerful. ? I have the 2402 and converted it to fit the GWS RD props by installing a longer 3mm shaft. Gets quite hot so you cant run around WOT. Think this may be a better choice given its lower Kv
 simon.castle 510 points
Thats with an 8x4.3 which is lighter than the 8x4 DD ie 4.01g to 5.19g
 Maciej 33 points
BTW.

HUGE PLAY ON BEARINGS ?!!!!!!!!!!!!!!!!!!!!

NO GREASE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
 roberted5 104 points
A 8 by 4.3RD draws more amps than a 8 by 4DD.

Hello. Is someone tested it with other props? It looks like copy of Neu Neutrino motors. We're waiting for something bigger :)
slaanesh  424 points - 8/26/2010
 
It looks like there are several ways to mount a propeller on this motor: 1). Use the built in prop saver - however I need to mount a spinner and I have found prop savers are unsuitable. 2). Use a prop adapter - though there is no prop shaft to mount this. 3). If the built-in prop adapter internal bore is threaded, could use a bolt? 4). If the grub screws for the built-in prop adapter go into the bore, could secure a suitable shaft?
 roberted5 104 points
You could put a longer shaft in it.

1 thumbs up!
Good indoor motor.
Very thin, and lightweight

Be carefull, GWS RD props will not fit, you have to use GWS DD props, or an adapter.

Motor weight is 18.4g with bullet connectors

Results with GWS DD 8040 :
Voltage : 7.42V
7.1A
static thrust : 265g

Ordered two of these,18 gram on the scale for each and they work well for 6-6.5oz 3d planes. Smooth power and come with a adapter if you prefer slow fly props. Im flying the hk2403 in a 6.5oz plane with a 2s 500 20c pack. Copy and paste link in your browser to see www.link
