what propellers to use ....... basically thrust would depend on propellers as well, so how is the thrust given as 1440gms? Please help....

hi how many magnets or poles are in this motor
 magnusEl 1214 points
If you put the motor in a box of some type, you can end up with heating problems. The motor has 10 magnets.

will it have tons of torque like able to move 3 to 4 kg. im only running im the street nowhere else. thanks

Hi i gonna mount this in a 8th scale car do you tink it would be fast enough im running 80amp esc and 4s lipo 3.3amp. should i get a higher kv motor.
 Bsd Racing 153 points
and 46t spur and 13t pinion
 magnusEl 1214 points
Dont use an outrunner in a car. There will be collected a lot of magnetic debris on the magnets, and probably seize up the motor. Use an inrunner instead, look for what others have used for the same car...

what if i make a cover or box for the motor do you know how many magnets there are
 azrc_pilot 234 points
NEVER cover the motor with any kind of materials. You will over heat and burn the motor!!... Keep it well ventilated all the time.

I am running 1600kv heli outrunner, 1500w in savage xl brushless conversion, i also run same motor on tamiya tnx, so it will work! Only car esc's on HK wit high volt and amp ratings are not suited for more than 4 pole motors usually, i use boat versions, now they have also with reverse and all like car esc firmware:) Stiff front plate motor mount is a must have for this kind of conversion!

Can any one tell me how far apart the mounting holes are. thanks would any one know how long it will go for on 3300mah lipo.
 magnusEl 1214 points
They are 25mm apart diagonally. Thread is metric M3.

Can i use it on HK550?
 Dongskie 228 points
I have a related question, I need a motor at this Kv range 800-900Kv and I will be using it for an electric conversion for my Hirobo Shuttle ZXX. Will this motor be good enough at 850Kv on 6S? Thank you

would this motor be an ideal motor for a quadracopter?
 dhruv 103 points
Yes, a very big and strong quad.

Anybody know what size bearings are in this motor?

Hello at all, can anyone tell me, if there are 3 or 4 mounting holes on the Top? (M3 screws?) Thanks in advanced.

Will this fit into HK500, planning for a quadblade thus require lower kV motor. thanks
 engineersupreme 66 points
Yes this fits HK500, have just finished installing on a scale 4 head, not run yet, I have installed it with a YEP 80amp ESC, for the ultra scale slow spool up.

Did one of you disassemble the Motor? I think about putting on some new windings to bring down kv.
sidd232  646 points - 1/6/2012
 
following an advice from a friend i will use it in a YAK carbon Z from eflite, have in mind 70 amps esc, 6s 2200mah and 11x5.5e propeller, let's see what happens.

Can anyone tell me how many poles and turns it have ?
 Pani. 12 points
10 pole. Don't know the wind number.
 magnusEl 1214 points
Pani is right, it has 10 poles. Number of windings is 7 turns, Rm is 34,7 milliohms, stator plates is 0,3mm thick. I am planing on a rewind for the ChangeSun 90mm fan, and is thinking of a LRK winding sheme. Original it is DistributedLRK.

can i use this motor to power my rc boat??
 spitfire2010 640 points
No reason that it can*t be used in a boat

If the kV is right, this motor is great choice for MSH Protos 500. Price is 5 times cheaper than Scorpion HK3026-890kV...
 CAYESA 303 points
Have you tested it at a Protos 500? Stock motor are hot after flight and I don't want to buy the scorpion one because it's very expensive.
 Pani. 12 points
It is a direct fit on a Protos 500. The kv number is suitable for a 15 T pinion. It is lighter than the stock Protos Lipotech motor.
 CAYESA 303 points
Are you using 15T with 6S? With lipotech stock motor and 6S I use 13T and I have enought rotor speed. If you put that pinion with 6S you'll have insane rotor speed.
 Samo Cankar 489 points
I used 14t pinion with 6S 2650mAh lipo cells... With 15t, had too much rotor rpm for me (intermediate skill).
 CAYESA 303 points
I have the 13T pinion and the stock pinion. I'll try the 13T with 100% throttle. Thanks a lot
 Samo Cankar 489 points
13t will be ok for normal flight and some basic acrobatics. 3D manoeuvres require 14t and for hard 3D you need 15t...

Is the quality comparable to Scorpion motors? What sizes are the ball bearings? Are they well balanced?
 Pani. 12 points
Alex the motor I received is a very good quality wound piece and balanced very well. It has big enough bearings top and bottom.

Shaft 5 mm - for HK 500.
 2Doggs 186 points
at 850kv, and running on a maximum of 6s, it would be useless on a 500, unless you could use a 23t pinion! Must be aimed at helis with a smaller maingear than the HK/Align.
 morphine 407 points
It has fixed wing potential.
 mujid 6 points
yeah ,suitable for plane not heli.
 spitfire2010 640 points
I have bought the critter to use in a fixed wing Air Craft. looks like a sweet motor...
 alexf1852 1 points
I bought a couple of these for my two MSH Protos. Very good motor for the price. 850Kv is perfect for using the stock 15T pinion. Power is almost as good as the Scorpion that is now discontinued. It still gets hot though.
 CAYESA 303 points
Are you using this motor with &S and 15T? I thing the head speed must be too high.
 Alex 5 points
I'm using 6S and 15T. But I also have a YGE ESC which I run at throttles between 60% and 80% (2650 rpm to 2850 rpm). I'm planning to switch to 14T soon but for no particular reason other than to take advantage of the new MSH shaft. Yes the new MSH long shaft that doesn't use a pinion adapter (for 14T) does fit this Turnigy motor. You will need to drill a hole on the bottom plate so the shaft can come through about 0.5mm. But it works great.

How are people getting 2800rpm with a 15T pinion and 6S on an 850kv motor?!?

Motor is very well made and very powerful!

I mount it in 1650mm wingspan and 1,3kg Hotliner (Flash) with 6S 2650mAh lipo cells and Aeronaut 10x8 floding prop.

This setup can provide more than 1400W with fully charged lipos (22,2V & 70A). On the ground motor becomes hot very quickly, but after landing it has no more than 60°C.

kV for mine aplication is little to high and because of that the prop needs to be smaller.


Came in small white box, with 4mm bullet connenctors already solderedc, but with no screws or mount adaptor!


Price is good for motor that size and power...

Munted in Protos 500, very hot after flight, I can even smell burned chemicals, still working (30 flights), very poor balancing (motor balanced but rear plate misaligned (made some holes to balance it)). Power about the same as Scorpion 3026 880kv but little less efficient.

Mounted in a Protos and works better than stock motor (lipotech). Not too hot and much power. Used with 15T and flat throttle curve at 85pcnt have enouhgt power to make 3D. Maybe scorpion one is better, but this is 6 times cheaper. Fully recomended.
