Hey,
You can use this Motor with an 8x4 APC prop as a pusher.
Then you get about 540-630g thrust.
I use this configuration in an f-22 foamie
Hope i helped you *)
ok , the motor may be on back wards but you must ensure the prop is still in a pulling position, imagine it is on the front of the plane and mount it accordingly to the motor
Anyone know actual weight of this motor? (not shipping, but out of box weight)
Also, Starting to build my first 3D and know low Kv values are better - but what about thrust to weight ratio? In standard sport/park flying, I usually go 60-75% higher than the loadout weight. For 3D should I need a higher power to weight ratio or less?
Thanks in advance.
I measured on my gram scale (also from HK) and it read as 27.6 grams including the wires. You are correct about low kv is better. I usually go for around 1.5:1 to 2:1 thrust ratio with my 3D planes. It really depends on what you want, for floatiness, go for a slightly smaller motor, for fast or hardcore 3D, I would say a slightly larger motor would be more suitable. Also, one more thing, I would personally go for the Hextronik 24g 1300kv motor on a 8x4 or 8x4.3 prop for 3D flying. I hope this helps.
The max amp draw is around 10 amps. You should be getting 10 amps with a 8x4 prop. If you are getting that much with a smaller prop, something is wrong. Make sure you balance the prop AND the motor, and I would suggest using the prop saver that comes with the motor. It reduces vibrations greatly and saves a lot of broken props.
Like I said, balance the prop AND the motor, and use the prop saver that comes with the motor. You should get a tighter band for it though, because the one that comes in the kit is a bit loose. If that doesn't help reduce amp draw, then it is possible that you got a slightly different motor that is not wound properly and draws more amps.
I am flying a 3D plane and want to put this motor to my plane. But what is the difference between 1300kv, 1500k and 1700kv of this motor? I can not decide which one i shall use. Can u please help me :)
Thanks a lot... XD
(And buy the way, which paints do you use to paint foam? =) )
Use the 1500kv with an 8x3.8 prop. it gives good thrust for 3d flying. You will need a bigger prop for the 1300kv and the 1700kv with a 7035 prop is good for sport flying. for paint, use waterbased acrylic.
I have this motor on a profile amous Moses and my 2 friend have the same planes , motors , 3s , 4x8 props etc but I'm running a Blitz rc 20amp esc and my planes just does not have near as much power is the other 2 guys planes with same everything excerpt as I said my 20amp esc . One guy suggested I find out if my new 20amp esc needs to be calibrated as in maybe it's not letting this motor turn up 100% ?? I can't find anything about the esc ??? Any help would be great guys . Thanks
Not much you can do to get more power from your ESC,just make sure the travel adjust on your throttle channel is set at 100% in the full throttle position.
I want to use this motor with a Mini Super Cub. These are my questions.
Will I be able to mount it directly to my Mini Super Cub with out any ADDITIONAL spacers or adapters? If not, what will i need?
Will I be able to use this prop?

I will be using a rhino 610 mah lipo.
Thanks in advance.
My Mini Cub motor did not work. I have ordered the HexTronik 20gram 2300kv. It has almost the same dimensions as the 1700kv that comes with the plane. It should arrive in a couple of days. I'll let you know how it turns out...
for 3000kv if u use 3s lipo u must not use above 5 inc prop for safety of the motor so ı* think 3000 can help to you, if u dont want 3000 kv , ı* prefer 1500 vercion
I solder it directly with a "mistery becs" they can change the rotation direcction, so, there is no problem to solder it in the wrong way. By this, you can save more then 7 grams.
I agree with you these engines are very good for Aeros electric weighing 250 to 400 grams have two more years never gave a problem and Aeros electrical power to alleviate the more you improve weight
Im flying my hobbyking j3 on the 3000kv version of this motor. It weighs approximately 480g. I imagine this 1500kv motor would be a better choice for planes over 300g. Hope that helps.
I am flying a foamie that weighs 7 1/2 ounces including battery.Motorworks well. I have 5 or 6 of these motors on foamies. Very good choice. I use 8X3.8 props: www.link
I use the 24 gram 1500kv on 3d planes that come out around 7oz auw with 2s 360mah rhinos, but they can easily haul around a heavier battery for windy weather or sport flying
Conclusion : fantastic small engine with extra power compared to the 1300kV model and with still a very small intensity.
Highly recommended -)

Weight Motor: 24,7gr. Weight Mount: 2,8 gr. Weight Propsaver: 2,3 gr.
After arrivel, i turned the motor by hand and hear a grinding inside the bell. I have to abrade the magnets and the stator to get a free run inside the bell. The windings are very poor - two stand 3mm out of the stator in the air!?!
Test data: GWS 7035: 6,9V - 3,7A - 8.800 upm - 184 gr. Thrust - ETA 60pcnt GWS 8040: 6,9V - 5,8A - 7.200 upm - 280 gr. Thrust - ETA 61pcnt GWS 8043: 6,7V - 6,1A - 6.350 upm - 305 gr. Thrust - ETA 53pcnt
I think with a new winding you can get up to 70pcnt ETA - let´s see if i will do that... UH - you can make it better, for example the "TR2204-14T" - Motor!
Best regards Andy

really good motor.1300 kV or 1500 kV any model, two of them very good.I'm using my own I did depron model.My model 260 gr. I'm using the following combination: *TP Slow Fly Propeller 8x3.8 *TowerPro 9g w12A Brushless Speed Controller *Rhino 360mAh 3S 11.1v 20C Lipoly Pack.
With this combination, approximately 390 gr. I'm getting traction. My model flies 8-12 minutes.(longer fly in windy weather). I am very pleased. I definitely recommen
Pulling 430g with an 8x3.8 prop. Perfect for small foamies and shockflyers. Only problem is those hard wires. I broke one wire directly from the motor on first flight. Replaced it with silicon wire, perfect! Still giving it 5 stars!
