Dunno.. but it's of standard spacings. As in it will fit most any current mountings

I would say no. Max volts is 9 volts. would burn after a while.

 __bare 709 points

Nonsense.. with a 1550kv one could even go 4S... with an appropriate prop tho :-)

Hi Sam, These Motors if they come with what is called a "PROP - SAVER" will come with an O-Ring, which should hold the prop and centers by itself... (nice feature). In a crash landing, prop might be damaged, but as it is only hold by an O-Ring (=Rubber Band), O-Ring should give way and release Prop, Prop than disengages and land's still intact somewhere close to crashed plain... THAT's THEORY.... Sometimes it works, bu only if engine of aircraft was stopped prior crash. rgds, manfred

Yes you are missing prop adapter, you have 2 option #1 PRODUCT ID: GON-D3T6 or PRODUCT ID: GS0162M #2 PRODUCT ID: OR019-00501-3

these motors come with ONLY what is in the photo. A prop adaptor needs to be bought separately. But Buying one from HK is iffy as often they are either Goofy or silly large. Best is to buy a motor that hasthe needed accessories included :-)

I tested this motor with a 7x4 prop on a 3s and got 8.8amp and 450gr thrust.

Had the same problem: Best, You buy a replacement shaft like the Turnigy EasyMatch Park250 Series - Replacement Shaft, it's a little bit longer, but has the grove where You need it. What's too long can be cut after swapping (DON'T FORGET TO TAPE THE HOLES OF THE MOTOR WHILE CUTTING!) rgds, manfred

You can push the shaft out and turn it around, then re-install the "E" clip. We do this all the time with motors like these.

Thank you both. Great help. Happy flying.

For the holes with the most distance it is *: 18mm. The other pair is 14mm across. By the way this motor uses 2 different size screws, bigger screws for the longer distance side and smaller screws for the shorter distance side. Hope this helps!

OK, but what is the size of the screws? I have motor, but didn't come with screws. I need longer distance screw size. Thanks.

7030 or 7040 should get you there.

 customer5 289 points

I have a 7040 prop with 3S and it pumps out over 400g of thrust! Gives my 300g glider unlimited vertical! But it gets really hot so propping it down to 7030 should be more than adequate.

How many Ampere draw with the 7040?

_Ufir 10mm should be plenty for a prop saver!!!

 __Ufir 18 points

if I put the prop to the shaft - I can see only 1 mm of shaft

 customer5 289 points

Look around if you can find a longer 3mm shaft. The one provided is too short. That'll solve your prop saver issue. Otherwise you'll need some sort of a prop adapter collet to mount them.

Good to know. Thanks.

I bought one a couple months ago. Was in stock at that time.

Hi Andrew, The C20 is back in stock :-)

 Sawdust 1605 points

In stock now.

8x6 would fry this sucker even on 1 cell. Im guessing 4.5x4.5 would be reasonable for it

 JHBorn2fly45 27 points

I am using a 2S setup on this motor which i have on a Dualsky Depron Foamie.

500Mah Nano-tech 2S/8x4APC SF/Mystery 12A ESC=

80W at 7.6Amp draw. Motor, batt and ESC is cool after 6 min flight

I run them on 3S with gws 5x3 3 blades on a mini quadcopter without any problem.

 Jackrr 224 points

Yes, it can. I've done it, in my case it was easy to do (I've tried it with another motor from hk and it got bent because I applied to much force, while still beeing unable to deliver enough torque). You just need a normal 1,5mm hex screw driver, get rid of one screw and you can change direction - I flattened the shaft to get good grip. If the shaft doesn't come out easily, don't apply force, but try rinsing it with oil and be patient.

Set the motor housing in an automotive socket (slightly larger diameter), then press out the shaft using a penny. You can then grab the shaft end with a needle nosed pliers and pull it out the rest of the way.

This is a small motor, I think it is too small for your demands

i think it gona be sweet cuz hlg usually are really light, about 300g when heavy!
so just try mate, really cheap, worth try!
