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
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...
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!
