USA warehouse now open. Our USA warehouse is now open! Low cost shipping and an ever growing variety make ordering from the US warehouse even better value!
The stated figures are from 3S. 2S will be considerably lower in both current draw and thrust for that Prop size, and personally I wouldnt recommend it. The motor is very much in its prime efficiency zone on 3S, so I never even bothered with 2S
I recently had a crash with this motor and now the rotor slightly touches the stator at some points. The motor still rotates, but at higher rpm the friction is obvious. Is there any way I can open up this motor and fix it?
Thanks in advance!
I would say you have bent the bell housing or the red spider on the front (bell to shaft part) Try and establish where the bend or warp is and use a vice/ pliers to bend back into shape. Otherwise, it is a $6 motor, buy a new one (plus a spare or 2)
Siddhartha, Malcolm is correct! These are inexpensive little motors that work GREAT! If you buy another, you'll have the stater and other parts for spares from the bent one. But that said, I take the mount plate off the bottom, and you can easily see which way the bell is bent. Bend it the opposite direction enough to get a screwdriver in the narrow spot, and attempt to bend it back the opposite direction. I've done this on a couple of mine. If this helps please award Malcolm. Happy flying!
Riaan, Yes this motor should do just fine. However, if you plan on using 10in props, I would suggest not going over 10x3.8. If you use 10x4.7 it puts quite a load on these motors and you loose efficiency and heat things up a bit but 9x4.5 or 9x4.7 should work just fine. I use 10x3.8 props on my tricopter with good results. Hope this helps and Happy flying!
For this motor to pull only 14.5a at 11.1v spinning a 10x4.7SF they are running at about 55% eff WOT! Has anyone put smaller props & pulled voltage/amp numbers? Maybe 9x5, or 8x6?
I use these motors for my tricopter and ave been very satisfied.... 18A ESC is enough (Turnigy 18A plush) but for better durability, a 25A would be much safer... Those motors can take lots of ***ping and beating before the shaft bends.... A bit noisy but very efficient and low consumming... My first flights with my now old lipos (tgy 2200mah, 20C, 3S) gave me around 15 minutes flight time each with 1047SF props. Just ordered 6 of them to have a stock because they are often BO and I hate waiting for motors to fly FPV :) Cheers
Great motor for Multi-copters. very efficient and reliable. 18A is plenty of ESC. I use the SS 18-20A and they barely even warm up with this motor and 1047 props. Cheap enough to order plenty for spares :-)
immersiveRC, I too use these on just about all my multirotor aircraft. These are fantastic on my tricopter with 10x3.8 props and 18A ESCs. Great little motors at a great price!
ImmersiveRC: You say you get 15min out of a 2200mah with 3x of these spinning 10*4.7? That works out to a 15min draw of 8.8a, divided by 3 motors (discounting other electronics draw) would be just under 3a per motor. At 3a w/10*4.7 these motors should give about 8-10oz thrust. How much does your tri weigh?
Senator315: I would recommend a slightly higher ESC. I have been using these motors in all of my custom planes and foamies and the 18A-20A range is the lowest I would go. But then again, I like to use throttle. But it's always good to leave yourself a little bit of extra give. Good luck!
i bought one of those, with a 3s, 20c, 1300mah bat, and a 25 amp esc to my 3D foam park flyer. That's a good choice? thanks! and sorry for my bad english...
leonardo, I'm now running 10x4.7 props on my tricopter with these motors and they do a great job. 8x3.8 props work fine as well. The 9x5 should work fine but I've not used them with this motor.
Normally I use a 8x4 (2 blades) propeller on my plane, but I want to replace it with a 3 blades one. Wich size should I use to anchieve same or closer trust/consumption of 8x4 one?
Thanks in advance.
Hi Doug, probably the bearing are 3x7x3. If it is correct you can find it here at Hobbyking (PRODUCT ID: GT600-030703) . It costs USD 1.21 for 4 bearings. (30 cents each bearing... its worthy to replace it)
Doug, I would recommend getting another motor. You may find getting bearings for this may cost almost as much or more. Use this as a spare motor and lube the bearings on the new one. Hope this helps and Happy flying!
I agree with the above replay. It is cheaper to by a new motor. I've used 7 of these motors and i'm very happy. 4 of these motors are on my 1,2 kg quadricopter with 9x4,7 propellers. happy flight!
aerodutra, This was my first successful quad and I Had four of these motors with 18A ESCs and used the HK V1 multirotor control board. The arms for this Xcopter were 24in and made from 24in aluminum towel bars. One was cut into two 11.5in pieces and sandwiched between two discs of 1/8in hobby plywood. The props were 8x3.8 slowfly props and I used a 2200mAh 3S 40C battery. Hope this helps and Happy flying!
Viktor, Wow! That's not long at all. I was getting about 7 to 8 minutes with a 3S 2200mAh 40C battery. About 5 to 6 with a GoPro attached and about 7 to 8 with a GoPro and a 3300mAh 3S 45-90C battery. I recommend using Hi C rated batteries because of multi motors and ESCs. A 40C should easily provide 10A to each motor (40 Amps Constant). but just hovering and not being aggressive, it uses less than 10A per motor. It's when you tilt it forward and push the throttle hard that the battery leaks power like a bucket with a big hole in it. But it's so fun! ha ha Happy fling!
Does this motor come with any acessories like mount, prop saver, connector etc?? Which acessories we need to install this motor in the Reaktor plane??? (REAKTOR-KIT)
Hello friend, it comes without connector, propsaver or acessories. It is only the motor with this round mount. To install it in the Reaktor plane, you will need propsaver 3m, propeller 9" or 10" and connectores gold 3,5mm.
Yes friend the 3mm propsaver will fit in this shaft. I already test a 3mm and 3,17mm propsaver, and the 3mm fit best is this shaft. I recommend 3MPRPSVR propsaver.
I used a 8X6 Three blades TGS with it, and a good performance with a 600 gr foam Stick, good speed and tork. Give a chance, maybe will be good for your purposes.
Gary, Please respond on my video and tell me where you get your 9x4.7 3 blade props. I've been looking for just that prop but can find it now where. I mostly use 10x3.8 on my multi-rotors with this motor but would like to find some 9 in. 3 blades that are not 9x6 (all I could find). Take care and Happy flying!
Video very good,must be a lovely place to live,which camera are you using?
With the props I just used an online calculator to check the size,not a100% certain who does them,will try and find out.
Gary, this was shot with a go pro camera. I made a mistake above. I meant to say 9x5 which is just a little too much for these motors for efficiency. I know 9x4.7 SF work great with these and have used them but for now I'm running 10x3.8 SF props and they do fine.
Hello friend, yes this motor is rocommended for 9-10" propeller. You can usethis motor in a quadcopter. With this motor and a 10x45 propeller I got 680g max trusth with 14A each motor.
I think you can try but personally i would not. Look, I'm so confident, because i use 4 of these with a 2 cells with no problem, so i think that maybe 4 cells is a little.. too much.
I have these on my quad and they are working fine, however, the bolts are not the best, and needs to be checked regularly. There are only two tiny bolts holding the motor to the base, as normal is four bigger bolts on most motors.
I agree and before i understood it, one of the motor has literally gone in flight :) for my friend Simone amusement...
One question: did you balanced these motors before using them?
Ciao!
Eu comprei este motor em um site da China por EUA $ 8,36 com frete grá*tis, porque aqui na HK o transporte é* tã*o caro?! É* uma ilusã*o comprar no armazé*m aqui do Brasil!
This is a very powerfull motor. I am using this in my 25 inches yak 54. Extremely durable and fast. Be sure you use a min 25 amps ESC. Great Value for money.

Construction of this motor is very good. Big area for cooling air on the front side and very easy to mount. I tested this motor using a stabilized power supply and a Turborix ESC 18A with different props.
Idle current at 11.1 V is 1.16 A Temperature was OK during the test runs, also after 4 minutes at 13.6 A From my point of view a good choice for a low price.

This motor HOVERS a 12oz Foamy on a 3 cell Lipo and a 9x4.7 SF prop at half throttle!!!!!! I thought I would have to worry about weight during my build. The plane ended up a little heavyer than I would have liked, but this motor will pull my plane vertical from a tail touch with out hesitation!!! It is advertised with up to 24oz of thrust on a 10x4.7 prop. I am getting that with just the 9x4.7 I have power on demand, I have not even hit full throttle yet, and at the end of my flight, the motor is still room temp!!!! You will never find a motor of this quality for this price again!!!! Get your wallets out! when this motor is back in stock,,,, it is going to be a race to see who will order them first. You,,,,,,or ME!!!!!!

I mounted the motor in a small (ca. 750 mm span), light ca. 300 gram EPP Curtis P-36 WWII fighter model.
The plane flies very nice and "for ages" (ca. 25 minutes) on LiPo 1300 3s1p and prop 7x5 APC electric. YES 7 inches diameter! It have got enough static thrust and pretty good speed. All standard aerobatics can be done. With APC 8x6E plane got near-ballistic performance but the motor became already noticeably warm.
The sticker claims props 9-10 inches at 11,1. Well, I'd use 9 inch, but only in applications where you do full-throttle only time to time. With a fighter the temptation to go full speed ahead almost all the time is so strong ... 8)
The other factor to consider is the prop pitch. If one wants thrust and don't care too much of speed, smaller pitch could be used, and then 9 or may be even 10 inch diameter shall be fine.
5 stars is very well describes my satisfation. And having in mind very good price - shall be probably 6 star )
