I have two of these motors...they are great with 7x6 props...but I need to replace a shaft..where can I get one...I know the complete motor is cheap, but I like to replace the shaft if possible...can anyone help?
I would say that a 6x4 is the most efficent of the 5-6 inch props, as thats when 5-6 inch props have a dramatic inrease in thrust, but I still dont think that you are going to get 700 grams of thrust unless you run a 4s setup. Hope this helps.
hi guys i have a dji f450 clone and have 4 of these on it i am trying to use 3mm prop adapters on it but they dont seem to fit ? can any one link me to what i need to buy to fit my props on thanks
Danny, the shaft on these motors is 3mm. The adapters you have may be a bit snug but should fit if they are 3mm. I've noticed that collet clamping adapters tend to be a little difficult to get on but do if you force them. Sorry I couldn't be any more help than that, Happy flying!
sunil, if you have a light enough airframe, you can go up as high as a 10x3.8 prop with this motor. But it it has to have a lot of power to lift, the 8x3.8 would be better and the 8x3.8 does seem to fly much much more stable on multirotors. This is using 3S batteries. Hope this helps and Happy flying!
Woops! Sunil, I mistakenly gave the info for the 1200kv motor above and not the 1534kv motor. For this motor, if it is a light airframe, 8x3.8 props work great. but for a heavier load, 7x3.5 props would be better. Still again, the 8x3.8 tend to be more stable. Sorry for the confusion and I hope THIS helps.. ha ha!
You can use the GWS 8x4x3blade props just as well. The CCW are PRODUCT ID: GWPRO002S3D, and the CW are PRODUCT ID: GWPRR002S3D. Don't be too worried about how they are labeled because Multirotors perceive rotation from the top or front of the prop. Airplanes perceive from the back and that's why a reverse prop will appear as a CW rotating on a multi. Hope this helps and Happy flying!
Sunil, The pitch speed (4.5) might be a bit too much. 8x4 is about as much as you should go with these motors. The spin pretty fast and can over heat even with the 8x3.8 when flying all out agressively. I suppose it all depends on what you are doing but I've not even tried 8x4.5.
Always try connect middle one of motor with middle one ESC. Others two you can connect in any way - nothing will damaged, just motor will working with different direction. For example if motor was rotating right and you swapped 2 edge wires (dont touch middle one) now motor will rotating left.
Even if you have a ubec, you still need an ESC to hook the motor up to. Most small esc's have a bec built in. Once you have your esc , hook up the three wires from the motor to the three wires on the ESC. If it is spinning backwards then switch any two wires. Also remember that you cannot have both bed and ubec.
Not sure exactly what you mean by a and a-wire. but if you are talking about an a wire on the motor matching up with an a wire on the esc then there is no such thing with this motor. Plug the motor into the esc and see if it is spinning the right way, if not then switch either two of the three wires with each other. Hopefully this video will help as well.
La maxima potencia en este motor es de aproxmadamente 220-230 wats., que se alcanzan en 4 celdas y con hé*lice de 7x6. (14,8V x 15,5Amp) De todos modos hay que probar con watí*metro y que no se "tueste" el motor por exceso de amperaje
Espero que esto te ayude.
you can use with EDF. But higher KV motors are good choice for EDF.search hobbyking for EDF motor & you can find them.Dont forget to check whether the motor shaft fits correctly with EDF unt.enjoy flying.!!
What you saying it's correct in any case, the screws should be glued, and actually it was loose on one of the motors, but not on the one that was twitching and sometimes stopped for fractions of a second.
Check the Alignment pin for the stator. Might be loose. Allowing the stator to wiggle. The pin runs vertically between the stator and the bearing housing. You can Epoxy or lok-tite it. Just let lok-tite dry for a few days before you try to fly. Epoxy:24 hours.
During the fly, one of such motors stopped eventually for a second and crashed my quad from 2m height. Before the crash, the quad was shaking and spinning of this motor was not stable.
After the crash it was running on the table (w/o prop) as usual. How can I know where is the problem - in the motor or the ESC ? I use Red brick 20A.
I would check the motor base set screws. They come loose very easily, and the motor starts to wobble. I have had to epoxy every motor into the base with high temp, 3200psi, 24 hour set epoxy. Then I have to Lok-tite every set screw, including the one on the propeller shaft.
Ooops! Sorry, I mistook this for the 1200kv. This is the 1534kv. Still use the 18A ESCs and 3S batteries but smaller props. I have 8x3.8 props on my wood tricopter. It is very fast and does some great aerobatics.
anyone tell me how can i fix this motor again. my motor was crashed, but i can fix it again. the thing is i don't no what is the coil method in this motor, please tel me what is the coil method and how can i fix this???
attach a file or video thanks?
praneeth, Because these are such inexpensive motors, I would just purchase another and use the older one for spare parts. These are excellent motors for the price! I use them on almost all my multirotors.
you are welcome.SOrry it is around 250grams.I just built my own kit with the styrofoam and fully taped it to be strong enough.I want to build my 1st plane to fly in highspeed :) . thats why I chose that motor.& I just wanna keep my budget low beacuse I am new to rc.If I finish building my 1st plane successfully, then I will move to the next level with some experience.I appreciate your suggestion for my plane.If there is any better motor or battery,please let me know.
At that weight you should be fine. I started the same way by making a foamie and using this motor. Since then I have moved on to faster and bigger planes. One thing that I was always told by the people at the local hobby shop was "don't worry about speed". I never liked to hear it but they were right. Your electronics setup seems to look just fine. One thing to always keep in mind (which you did already, planned or not!)is to get a speed controller that can handle a little more than what your motor is rated for. (ex: motor is rated for 18amps, then use a 20 amp speed controller). Just a general rule of thumb. Always glad to see people coming into the hobby. Its hard at first but gets much easier. If you ever have just general questions (or feel like showing off your creations) join RCgroups and post them there. I joined a little while ago and love it. Would love to know how everything turns out. Good luck and happy flying!
Got off on a tangent and forgot to go back to it but what I was trying to say is don't worry about speed at the start. Speed is not your friend when starting although we all wanted it to be. This motor should suit your plane just fine.
Karl, thank u for ur reply...I am planning to use 20A HK blueseries ESC & Turnigy nanotech 850mah 3s with this motor,3 TG9e servos,7x6 prop APC.I have already built the plane KIT(similar to Tcub) it weighs around 3.5os. Is it possible to build a 3D plane with these??
First off thanks for the credit. Here are the connectors that you need for your esc to work with your battery PRODUCT ID: AM-1024Bx10. I would spend the extra money and get the HXT900 servos because they seem a little more resilient than the TG9e servos but that's your call. Quite a light plane for this motor as this thing is pretty weighty for your 100g airframe, but once again' that's your call. Did you get the kit from Hobbyking as maybe there is a better motor of choice for that plane. Not a 3d pilot and have never tried it but can't see why this motor wouldn't work with the right sized plane. Let me know about the kit you have as there might be a better motor to use. Thanks again for the credit.
Yes you need a set of bullet connectors to connect this to your esc. You also need a battery connector from your esc to your battery. Here are the bullet connectors that I use with this motor (they work great) PRODUCT ID: AM1001A. What battery do you plan on using with this motor and speed controller as I would be happy to help you find the right connector for that as well. Also pick up a thing of 5mm heat shrink ( PRODUCT ID: WH-5MM-BLACK ) to cover your bullet connections once done soldering them all up. Hope you enjoy the hobby.
hi Tomas,depends on prop used.to get general info look at reveiws of this motor (static tests)max amps/prop ratios that users have given.Karl is correct as this is a rule of thumb and many agree.example- unless you have a separate lipo running rx/servos/voltage reg etc, if you burn the esc thats also powering your rx/servos during flight say goodbye to your plane (no control to aleast glide home)goodluck
THe speed controller shouldn't be an issue as it only delivers as many amps as the motor needs. I think that you have blackened the coils because you are drawing to many amps from the motor. If you have an amp reader measure how many amps you are drawing. My best guess it that you have to large of a prop on this guy. I feel heat on mine when running a 6x4 prop on a 3s, but because it is only a 3s it does not get hot.
Me as well and at most the motor is a little warm.

Very nice build motor. Also power and efficiency is more than OK. Tested with 4,7 x 4,7 Graupner CamSpeed: V A rpm 11,06 7,55 15835 www.link x 5 Graupner CamSpeed: V A www.link easy to improve the internal cooling my modification of the three spokes. Simply abrade to bring them into a "propeller-like" shape.

I have multiple planes with this motor. The FC28-12 brushless motor is comparable to the BP-21 in performance. Perfect size with a sport 7X6 prop at 17A to carry a 15 oz plane at 70 MPH.
I like the motor but have had trouble with what I thought originally was bearings on three motors but ended up being debris on the magnets. This debris looked like fragments of a broken magnet but all of the magnets in the motors were intact. All of the motors came on the same order.
It's a little difficult to clean magnet fragments off of the magnets. The E clip was easy to remove and it was easy to remove the shaft. I used a dry cloth, toothbrush and air compressor and finally got the magnets clean and saw a drastic improvement in motor performance.
I will buy more of these motors but if they grind at all I will check the magnets and bearings.

Amazing power to weight on my stock stryker 134kph 7x6 apc style prop 30amp esc 2200mah 20c approx 15min flite time full power all the way battery get warm motor stays cool only down side as pusher setup puts load on the small bearing tends to not last long but for the money just buy some more for spares easy to mount on brushless mount put motor on outside and if you got a spare motor put removeable mounting plate on in side of mount and bolt together you wont be dissapointed good cheap setup

I love theese babys. Low cost and enough power for my 350g Delta with 3s HC Rhino 1250mAh and APC e 7x6. That´s enough for vertical climb. 5 Stars!!
