520g. There is some more detailed data under the "files" tab.

 DodgeHobby 176 points

Id go for the bigger 2836 motors for that frame. Although I have these on my Dead Cat and they are doing ok, although getting a little warm

 charlie33 10 points

2836 /8 /9 or /11 ?. And the propellers size with this motors ?

 DodgeHobby 176 points

With this motor, 7/8" And the 2836/8 will do fine with 8/9" props. Lower KV is normally better,

 charlie33 10 points

ok thanks, and with 2836/8 what lipo battery is better?

 DodgeHobby 176 points

Either 3s or 4s, with 4s use smaller props =]

 jsrock3 138 points

Multistar 15 amp is what I use and it works great. Easy plug in too.

 jsrock3 138 points

I used a 3 cell 2200mah lipo and 8x4.5 props on a x525 v3 quadcopter and figured about 2080g of thrust total.

I do not recomend to change the motor shaft for some reasons. First, you will spend a lot of time doing it and you could damage the motor case. Second: you'd lose efficiency because it would not be as perfect as the factory, and third: this motor is so cheap that change the shaft wouldn't worth.

 alex.khoroshko 339 points

First two reasons are nonsense. Just don't hit the bearing into its central part during assembling/disassembling and motor will be like new or even better (some shafts go sloppy from the factory). BUT! This motor is imperial (I mean the units of measurements), so it's very hard to find the replacement shafts and bearings. Anyway, buying the new motor is good idea - full bearings set usually costs over 10$ for 5 or 10, shaft - about 1.5$ pieces and they find the use very seldom, usually in a crash the can is bent or motor burns out or alike (I have the 2836 motors in a quad for some time, I've burned one motor and bent the can on the other - my spare bearings and shafts are useless for now).

 Raphael 8 points

So Alexander, I guess you are an expert ( and smart fool guy ) who think is easy to change this shaft?!? For your information this shaft is too tight fited into the can and, if you don't have the right tool you'd damage the motor can. And you are saying that a new shaft would be better than the factoty one?!? My God... Better hear it than be a dumb!! LOL

 alex.khoroshko 339 points

Here's a proof of the possibility to disassemble the motor without any fancy tools. You'll find very much more on youtube by "brushless shaft replacement". And if you would use google, you would find out, that some motors in some cases tend to have the shaft rotating in the bearing so that the inner ring of the bearing stands in place forever. Too bad for you not to use google before being rude.

 alex.khoroshko 339 points

Hmm, video attachment failed. One more tryout

 Raphael 8 points

Sorry, but who was the first being rude here telling the others answer was "nonsense"?? This motor in the video is a litle bit diffent from the one sold here, and I guess, much more expensive worthing change the shaft. I have a tricopter with these motors, and one of those hit the ground moving the shaft a little bit foward and I had a big work pushing the shaft 2mm to the place because it was too tight, ans you come telling me it is easy to replace the shaft?!? Come one smart guy!!! And to finish: not everyone like you has those tool and pratice to change a shaft like in this video. End of discussion!

 Raphael 8 points

I build and sell tricopters with these motors. I would recomend using a 8x4 gws prop, instead Airscrew ( too heavy props ), and for the Esc, I recomend at least 18amp. A multistar 20amp would be great( remember that you need only one esc with BEC, the others could be OPTO, those cheaper ones)

 Vivek 5 points

I always recommend higher amp esc's also ones that you dont have to replace if you decide that you want better and faster motors, otherwise I use a 2200 mah on my quad, and i use the kk2.0 board. I dont use Airscrew props they are too heavy, i use 9x4.7 gws props

 Senator315 529 points

You'll need 3mmx7.5mm. The frame should come with the longer screws.

 un4seen 60 points

You can't use the adapter type you're looking for, these motors don't have holes on them. I actually made that mistake myself, got adapters from "another well-known chinese shop" only to find out that motors lack the mounting holes for them. At least the collet-style adapters supplied with the motors are "good enough" quality, easy to balance.

 Claudio 86 points

Hi lorenzo, are you using 2s or 3s?

 Lorenzo.93 38 points

i'm using 3s...

 clambake 11 points

Hi...did you find these motors difficult to balance? Do you have any pointers for balancing these motors? I get a lot of vibration with just the motors, no propeller. At a certain speed, the shaft starts to wobble. Tried the tape balancing method with no luck.

 appala 3 points

clambake, have you checked to see if you can wobble the shaft back and forth when its stopped. your post made we wonder if there is a bearing issue or a bent shaft that would cause what you are seeing. if the bearings were loose, it would have a lot of play in it...

 omero 12 points

HK-SS30A try this ESC's. Just flash the with Simonk firmware.

 Kitan 130 points

How should I flash simonK? Are ISP pins broken out, or I would have to solder pin by pin somewhere on board for every esc. Also, I should buy one without programming features or one with? Thanks

 omero 12 points

Download Flashing tool software(google it and flash the right hex file for specific esc) you should have PRODUCT ID: 332000007 Atmel Atmega Socket Firmware Flashing Tool, doing this will get rid of tedious soldering work and for the ESC the non-programmable one. PRODUCT ID: HK-SS30A Hobbyking SS Series 25-30A ESC

 Kitan 130 points

I have flashing software, I was just wondering if this exact ESC has ISP pins broken out, because $20 seems a bit too much for an adapter. I tried to solder pins to one of my atmega8 based ESC's and I managed to solder 4 of 6 in about 20 minutes. Then I gave up. I don't think I could do it 4 times, so I guess I'll just go for that flashing tool. Thanks.

 DaxFX 95 points

I have this motors running on my quad with hobbywing Quattro esc 4in1 with 8x4.5 props, lots of power and perfect combination

 Yurik 92 points

Disassembled 1 motor. It has worked for about 20 minutes. Top bearing do not even rotates, istead of this shaft easily rotates inside bearing. Bearings and shaft are greased. Grease is clear, nothing happened to motor, just bearings worn out, especially top - this one completely (rotates with cracking noise). The reason why this motor works (and will work for a little more) is that shaft rotates easily inside the bearings, while bearing not moving at all. Now will try to remove bearings and measure it.

 Yurik 92 points

(1/8 x 5/16 x 9/64) Get out bearing (then put back). It is hard. I used 3mm drill bit (plane backside) through the bottom bearing. As support from the top - metal round adapter from TV tuner (between tuner and antenna) fit very well. Held motor upside down on the adapter and beating the drill. Now I now it's sizes definitely. It is 1/8in x 5/16in x 9/64in (ID x OD x W) The shaft is definitely 1/8in along all length. And there is nothing interesting inside the motor. Everything is very simple. Everything is good, except bearings.

 clambake 11 points

Hi Yurik...did you have any luck replacing the bearings? How was the perform afterwards? Did you go with new motors instead of replacing the bearings?

 Yurik 92 points

I have ordered, but still not received replacement bearings. But I disassebled motor to measure bearing, then assembled it back. And it works as previously. I think bearings should not fit in place VERY tight, maybe that is why it is worked bad. So I put it in place just by fingers. Others work. Also not good (only 2 of 5 perform better). But I still use it. I have ordered other motors and received it. Parkfly-450. But they are too heavy, comparing to these. Too heavy for 330mm quad.

 Yurik 92 points

I have replaced bearings. On 3rd try it was easier. With new bearings works better, smoother, but difference not very big, because shaft has a bit smaller diameter and rotates inside bearing. So no matter if bearing good or bad if shaft slide inside inner hole. Under load new bearing works better (sounds better at least).

 Yurik 92 points

And now I replaced 5pcs. A bit used to it, so it takes about 10min - easy enough.

 clambake 11 points

I agree with you about the shaft sliding around in the inner hole of the bearing. I have an old SK2822 1200kV, this motor works great with no wobble. (Down side is HK obsoleted it with the SK3 series) I also purchased a Turnigy Easymatch Park300 1080kV and earlier experimenting looks promising. I have a Turnigy NTM Prop Drive 2826 1350kV I was using for a small biplane. I tried it on the quad and had a ton of vibration. I looked around on the net for replacement bearings for the D2822/17. I saw the ceramic bearings the car guys use, other than the quality looked questionable. I think you are right Yurik about the shaft sliding around in the inner hole under load. What we really need is someone to sell a matched shaft along with the bearings that has really tight tolerances with respect to the inner hole and shaft diameters.

 Yurik 92 points

Actually I think we don't need another shaft because we have to drill larger hole for it. For 8 dollars we just need a little better bearings. But I decided it is not hard to replace, so 32 dollars for 4 motors and 7 dollars for 10 bearings is enough. I can not say it vibrates much, no, it simply not tight. But especially for quad if prop are balanced it works not bad even when bearings wear out. I have bought Park450 and will try soon. At first look I thought wow It's heavy and shaft is enormous!

 TheThomass 124 points

I use them on a 450 size quad with multistar 15A esc's and 8x4 props. The motors were perfectly balanced and run really smooth. Best motors in their price class and great for multirotors

 Shurics 144 points

Tnx, I'll try then!

 Raphael 8 points

Are you sure you bent the shaft? I guess you bent the aluminum prop adaptor.

 Eeeeky 30 points

im 10000% positive i bent the shaft. actually bent 3 of them. Ordered new shafts and was sent the wrong ones.

 Raphael 8 points

I was wondering how to bent the shaft without bent the motor can, that is made of aluminum. I'm almost sure that the can was also afected. Like I said up there* I don't think worthy to have a hard work changing the shaft, having the risk of damage everything, with a motor so cheap. Buy another motor instead.

 Eeeeky 30 points

Sorry but its not cost effective. 9 dollars for a new motor, 89 cents for a new shaft.. Which one sounds cheaper? Shafts bend without hurting the motors all the time. The case is designed to be rigid. Im not going to have an argument like the last guy did. I know how to do it correctly, and if you cant replace a shaft without damaging the motor, you shouldnt be providing feedback to anyone.

 Raphael 8 points

So, go on it and replace the shaft...

 Eeeeky 30 points

Being that i posted this over 3 months ago, ive replaced all four shafts since then.

 ARINAS 90 points

hi kitan.
yes, it will work with 2-bladed 8x4.5" prop,but 12A esc will be at the optimum edge of limit in those combination,& expected that battery will provide 4~5 minutes otherwise im recommended u to use above 2450mah to fly more than 5min'.Zippy 2700mah 25c or 35c is the best match for ur setup.
anyway watchout ur esc & motor temparature,if it is to hot,u'll gonna have to prop down to 7"x4.5~6,but then considering u'll lose some lift trust.
& pls award me some more credits for my respond...tqvm..!

 Rodrigo 33 points

Kitan, you will need a 20A esc if you want to use 8x4.5 prop on 3s battery

 Kitan 130 points

I have 3 2200mAh 3s batteries at home, could I connect them together to get longer flight time because it would be better for me then buying new batteries?

 Kitan 130 points

Would 7x4 props(Product id: MA0740NEP and MA0740NE) be better? Also, would I get longer flight time with them, and would 12A esc be enough for them?

 jhon827 7 points

My setup with this motor is 15A Multistar ESC flashed with SimonK on a Q330 Frame with 7x4.5 three bladed prop running on 2200 35c nanotech and I get about 6 - 8 minutes flight time.

 Rodrigo 33 points

With 7x4 prop, engine intake is about 8A. You can use 3 batteries together, since they are charged equal and have the same characteristics,as brand, discharge capacity.

 Yurik 92 points

jhon827, please tell a little about flashing Turnigy 15A Multistar with SimonK. Had you changed pins, had you used kda.hex? about the motors: price is really great! But don't other feel the bearings a bit weak. I mean, that shaft began to "click" quite fast...

 jhon827 7 points

I just used the Hobbyking flashing tool. It's a lot easier.

 TheThomass 124 points

Hi kitan, I do the same. I put two 1550mah 3s 20C lipos in parallel so I get a 3s 3100mah 40C lipo! Just keep in mind that the extra weight will requirz more power so you will drain your batteries a bit faster. Works great for me tho.

 Haim 98 points

on 2s probably on 3s it's to big

 Rodrigo 33 points

Maybe on 2S, and you will have to measure the current, to avoid burning your motor or esc.

 Monica 1 points

To be safe side I would buy Turnigy D2830-11 1000kv Brushless Motor it's only $1.33 more but you got more flexibilities ones come to prop and battery size.

 Izane 7 points

Yes you can use 8x4 prop. Max rating for this motor is 10A so 12A ESC should be ok. I used the similar combination and my x quad fly like a charm. It is a good motor for quad

 Rodrigo 33 points

I'm using a 20A ESC and 8x4 prop, with 3S lipo. It's working nice.

 TheThomass 124 points

I chose for Multistar 15A esc's eventually, just some extra room in case I want to go for bigger props or other motors in the future :) Will 3s 1550mah 20C lipos be enough or is that C-rate too low?

 barfy 54 points

If you mean to use it with a single motor that's bucket loads, if your going to use that battery with four on a quad it'll probably be OK but your pushing it I reckon. Most of the time you should be about half throttle which might be 5 or 6 Amps per motor? which that battery will deliver. When you want to crank it up you may find the battery voltage will collapse and can create weird behaviour.

 TheThomass 124 points

Ok thanks a lot! I guess it will do for learning to fly quads, I'll order some others (2200mah 30-40C)for once I want to crank it up a notch :D

 ARINAS 90 points

thomass,im calculated, its is recommended that u use 2400~2700mah 23c .because this will provide safe redundant power level on flight & hovering. as barfy said,& im also experiencing same too,if battery is insufficent in any way,then ur quad will behave weird & maybe wobble to crash..
then pls credit me some thumbs-up.. tqvm..

 Rodrigo 33 points

Works nice with 8x4 prop.

 TheThomass 124 points

It all depends on the lipo you use. If he uses 2s lipos the prop can be up to 8x6, if he wants to use 3s they recommend using 7x4 props. If you go higher you might pull more amps. So if he has a 15A or more ESC, he could use a 8x4 prop, but I think 9x4.7 might de just too much. Maybe it flies for some time but if the motors are not designed for that their lifetime might be shorter. grtz

 Haim 98 points

I looked up the internet and I think that the inner part of the shaft is 3mm not 3.17, can you please verify that, because if it the case there are plenty that can fit.

 Rodrigo 33 points

you can use a 3mm shaft.

 Rodrigo 33 points

Actually, i bought a 3mm shaft adapter, but didn't fit. So, i had to increase the hole with a 3.2mm drill. So, the shaft is really 3.17mm

 Haim 98 points

what that i found out is that the exterior diameter is 3.17 , but inside the engine it's 3mm . he broke a shaft and would like to replace it.

 Rodrigo 33 points

Sim. Vou usar um esc hk de 20a no meu, mas um esc 25=30 tbm serve.

 Vagner 6 points

Pode usar sim, utilize també*m uma helice 7x4 que ele fai ficar bem economico!

 Galvão 3 points

Danilo, Você* pode até* economizar... Pode usar um ESC de 12mAh....Dependendo do seu projeto isso já* reduz uns 15 a 20 gramas...

 Rodrigo 33 points

Sera que com uma helice 7x4, vai voar bem um ugly stick de 1,2m de asa e 600g? a carga alar ficou em torno de 33g/dm2.

 Galvão 3 points

Uma 7x4 com uma bateria 3S!!! Mas eu acho que você* vai trabalhar um pouco forç*ado. Ai a sugestã*o é* aumentar o Esc para nã*o esquentar muito. Testa com uma hé*lice 8 també*m...

 Rodrigo 33 points

Estou usando bateria 3S. Com a helice 7x4, o empuxo ficou em 320g e a corrente maxima foi de 8A. Ja com a helice 8x4, o empuxo foi de 520g e corrente maxima foi de 12A. Meu esc é* de 20A. E ai, uso a 7x4 ou a 8x4 em 3S?

 Galvão 3 points

Em Que aviã*o você* instalou essa eletrô*nica??? Acho pouco empuxo 320g...

 Raphael 8 points

Recomendo usar uma hé*lice 8x4, esc de 18amps e bateria 3S de no má*ximo 1300mah: bateria maior do que isso ficaria muito pesada.

 Rodrigo 33 points

I'm using 8x4 prop with 3S lipo. The holder diameter it's about 4.8~5mm

 Haim 98 points

should work fine. it have more then plenty lift especially x4 :-)

 Galvão 3 points

Yeah, it is great.... So, use lightweight Esc (Ex: 12mAh) in your project..

 Rodrigo 33 points

I think will work fine. I measure the trust with a 3s lipo, 20A esc and 7x4 prop and the trust was about 420g.

 Haim 98 points

yes. it's nice and handy. I prefer prop saver over the adapter but when you get a free one ..

 Rodrigo 33 points

Yes, but the shaft adapter that comes with the motor is unbalanced, so i recommend you to buy a prop saver.

 Raphael 8 points

A tip, if don't find that clip at an screw shop, you can do the following: put a washer in the shaft, then roll a thin wire with a drop of CA. I bet it would be better than the clip.
