this is the best set up i can fond for this motor. I use this and love it. Iget around 575g of thrust
Prop: PRODUCT ID: H9011A
ESC:PRODUCT ID: HK-SS18A

Will be terribly underpowered.

You'll have to figure out how to mount them (at least I could not find a mount which could fit them on HK). Also they are not that great for quads that big. You'll be better off with stronger motors and bigger props.

ah... this stuff is quite tricky!!! you may use screw (may use metal strip to hold) passing through square. or simply stick it...

 meaty1 4 points

use small servo screw

any 15-20 esc will do buddy... there are lot of esc just look over...

15-18amp esc works great

 Kellyann 16228 points

B it does say the Best current range: 6~10A. So I can see a 10a working fine (with a burst of 12A). I hope this helps

 adammooren 616 points

this works best PRODUCT ID: HK-SS18A

You will get 1100kv motor, not 1800 kv. The photo is the same on both motors, as they look same, but are rated at different kv. :)

i got this last month and it still going strong its 1100kv though :)

 adammooren 616 points

they reuse photos sometimes, but this is definatly 1100Kv

 p3tras 240 points

KV means revolutions per Volt. So motors with more KV will spin faster with the same setup, but will have the same power (if motors are the same except the KV thing). So in short more KV = smaller propeller, faster model, but less thrust. If you want 3D model use motor with less KV, if you want fast model use high KV motor and always use recommended prop

 teflyer 151 points

I would not really reccomend either of the motors as they do not have that great thrust to weight ratios. However, the Ax 2308N does have a better thrust to weight ratio than the ST2204-1550.
I would use the motors used by RCexplorer in his V1, V2, or V2.5 version with either the 2213N 800Kv Brushless Motor or the hexTronik DT750 Brushless Outrunner 750kv

I use this motor on my quadcopter. Using 9x5 prop it stay cool. On 10x6 prop its barely warm. Its a good motor. Lightweight with good torque. If u r just starting i think u should cut the motor shaft. Make it short so less chance to bend the shaft.

 Ebuli 66 points

Yeah, good enough for those small parkflyers. And for this price, you can use 2 on your model :)

Thanks friend. HK should label or mark identical but different product, please.

Unloaded, it will be close to 1100rpm/volt, so 7.4V(2S) should give you 8140 rpm.

 greengo746 45 points

8,140 rpm on 7.4v but beware this motor do not have high torque. For flexibility, go for 28 or 35 size motor. U should be able to put it on a bigger plane when U progress and much more forgiving on your esc. I am using 28 size motor on 3d depron plane. Unlimited vertical and enuf torque for future planes. This motor on a slow stick barely can fly. 3/4 throttle to lift off and its a slow walk in the park after that.

 Igors 11 points

2s voltage is 7.4V. Motor 1100KV - rpm on 1V. RPM on 2S=1100*7.4=8140rpm. Good luck *)

 chanyote66 61 points

Not enough torque for a slow stick? I would have to ask your AUW of it. I run it only with 3s batteries... I use this on almost all of my Home built foamies, Amazing power for anywhere from a 200g up to my 700g fpv plane. I dont fly 3d so that aspect may be lacking but for the daily flyers its great! Running this with two HK-SS-20A esc's on my 1200g cargo plane can get it into a hover no problem with 8*4*3, 8*6, and 9*5 props... it gets warm with 9*5*3 so i stopped using those.

 meaty1 4 points

im running one on 3s 11.1v 1500mah
7.6amp draw
80 watt power
8x4sf prop
15-18hk esc
works great everything stays cool
plenty of power for my 1pound depron trainer

 greengo746 45 points

This motor can take 10A on average and around 14A max. Any higher it will get hot. The esc and battery are compatible but a bit over power. I think prop is around 8-9" for this motor.

 dudeman 18 points

i use this motor with an 18amp esc and 1300mah 2s lipos and a 10x47 prop, flies my gws beaver like a dream

 maxduca63 130 points

i am quite sure Yes. I have a lot of these motor and I play with 3s from 1,8 to 2,6 A but I do not have the ESC you mention. I use the turginy 30 which is very overdesigned but works perfectly. I have a couple of this motior working with 18 A ESC and they also work well even if the ESC comes a little hot. Therefore a 25 A should be fine. I use 8x4 prop.

 p3tras 240 points

No, search for motor with higher KV rating (recommended prop should be similar to your old prop)

 greengo746 45 points

for 6.5x40 prop u need around 1800 to 2200 kv. I suggest PRODUCT ID: AX-2308N1800. Same size and weight but higher kv not to mention dirt cheap. max esc should be 20A though. Good luck

 adammooren 616 points

This depends on how you plan on using your plane. I would recommend a 3S 1500mah or larger with two 15a esc. Because your battery will be powering two motors, I wouldn't use a battery with less than 35c discharge rating. If you are planning each motor to have its idividual battery, I would recommend each motor with a 3S 800mah or larger, each.

 uwete 18 points

With a GWS 9 X 5 3-blade it pulls 12 A at a full 3S Battery. A 1500 mAh Battery would do the job but full throttle time were only 3.5 minutes in a twin. A 2650 mAh Battery would give you 6.5 minutes for about 90gramms more weight. With smaller blades you can use smaler batterys.

 dudeman 18 points

what kind of question is that? why is the sky blue? how does a posi-trac rearend on a 67' plymouth work?

 TerroroftheSkies 4 points

Well, there is a finite answer and thats what I want, because different motors use different gauges of wire. I would like to wind it to a similar Kv, because there are a lot of different gauges of wire and depending on the gauge, number of strands, and number of turns determine the Kv or speed of the motor, lower Kv more torque higher Kv more RPMS. If you don't know, keep the "smart" answers to yourself.

 Scott 234 points

Great Idea! These are great little motors for the price! and with a quality re-wind, they should perform quite well. A motors efficiency can be increased when more time and effort are put in to the winding. I was thinking of re-winding a few of these myself to see what they can achieve! If you are going to re-wind this motor, I would suggest to use 0.404mm 26AWG wire if it is your first motor re-wind. you should fit about 22 to 26 turns on each tooth of the stator! and if you use 0.508mm 24AWG y

 TerroroftheSkies 4 points

yep thats what i went with, 26AWG with 19 turns per tooth finish with a delta. Performs great and i get great flight times.

 Rover00611 4 points

5429 is the 1100 kv motor. I just bought two and that was the marking on the bag.

 nguyentran 21 points

the bar code on the package is the id product of the motor. Say you open the url of the motor, look at the address bar, the last 4 digits correspond to what you find on the bar code. For example the 100kv is 5429

 Van 8 points

there is not any information of tips to identify which the motor with KV?

 vipulavs 1 points

here is the www.link can check that by this- go to this www.link means The Barcode eg- www.link

 Scott 234 points

The towerPro or hextronix 8mm motor mount that is found in hardware/motormounts should do the job for you!

I ordered a few of these www.link but the slot for the safety pin/stopper in the left end is a bit shallow... if it's enlarged with a dremel I think it will be fine

 BradleyK 69 points

i have 3, the are great, but quite a few people said this has a shorter life span the there better motors,

 Beaufighter 1808 points

This is a constant for brushless motors used for calculating. The KV is rpm pr volt (unloaded), so 1100KV at 7Volts = 7700RPM theoretically. In normal use, reduce the rpm by ca 1/3 for actual rpm with propeller. You can go to the forum for a more detailed descr1ption.

 fanny 512 points

IMHO lower KV=biger prop=more efficient. Advert states 1100KV Motor sticker says 1800KV????

 Ikarus 99 51 points

1100 kv is show you the turns per volt. for example 1100*11V=12100 turns per minute.

 knuflyer 24 points

Well, yes it is a little confusing... going against standard electrical nomenclature... But it simply means "RPMs times Volts used". So, if you have a 1100kv motor and use a 7.4v LiPo, then I assume you get 8140 rpms out... not sure where the prop comes into this, since obviously every different prop length/pitch range will really give you different answers... But I guess it is a generality... a starting point.

 volto 40 points

Yes the figure is for the motor with no prop attached.

 Valter 1 points

rpm/V = (rotations per minute)/(Volts) it means how many rpm you get per each volt applied!

 vipulavs 1 points

kv means rpm per 1 volt on the motor.it means this brushless Micro Motor have 1100 rpm (round per minute)for 1 volt(without the propeller).if you give 7.2 volt to this motor it gives 1100x7.2=7920
