Turnigy D3548/6 790KV Brushless Outrunner Motor

Hi Tony when choosing a motor the main thing you need to consider is your aircraft weight and flying style trainers 100w/lb sport 150 to 200w/lb and 3D etc anything above 300w/lb choosing a prop for that motor is slightly harder some manf recommend a starting point size but given the price of props having a selection of dia/pitches either side of that point is a great idea. to confirm a prop is not overloading your motor you'll need an inline watt meter though do remember a static test will return up a reading up to 30% higher than happens in flight. the esc must be rated at or above the max rating of the motor so for instance this motor has a max A of 40A so an ideal esc would be at least that and preferably say 45 to 55A Finally try one of the many forums out there for further advice and if possible join a club and pick the brains of the old hands

Just one problem here Matthew those accessory packs won't fit this motor as the shaft is out the wrong end unless it is possible to change the shaft's orientation.

This motor will carry up to 3 pounds for 3d flight. Use a 14 7 prop on 4s 2200 and watch it go!

BEST ANSWER CREDIT (should be) AWARDED!

 Matthew 7 points

Yes, the motor comes with the prop adapter and mount.

 Alex 18 points

Yes it's in the bottom right hand corner of the picture. If you don't get what you need you can also stop by your LHS, mine always has mounts and adapters in stock. Opps sorry^^

 Matthew 7 points

This motor produces 1.6kg with a 11x7 prop.

read up on RCGroups, there is alot that goes into an airplane flying. wight vs. thrust, which includes motor size and all the eletronics that need to be matched. CG (center of gravity) plays a part, along with the aerodinamic that need to be taken into account. Best thing to do is put the time into research, lots of help out there to guide you through the issues. Wattflyer**** has alot of good info on the math behind staying in the air.

It really depends on the resulting current by your battery-props configuration. With 4s and 12x6 props you obtain aprox. 36A at maximum. So i would use a 45-50A ESC. From my own experience Mystery or HK Blues series SC's work fine.

 hardrain 4 points

Thanks! Actually, my concern is also about compatibility with the Naza. Seems like there are pwm problems between the Naza and some escs... Do you know for shure that Mystery or HK Blues series work with it? Anyway, I'd like to stay above 60A.

 Manuel 2 points

Sorry, didn't know that there might some problems with pwm. Thought your question was just about max current for esc.

or would 3s 4000mah be good enough ?

 Karl Heinz 54 points

take 4s 4000mah... you have more power and a longer flytime!!!

 BrainFade 3 points

thank you

 kizashi 55 points

I had a Nexstar which is a big airplane and I would believe that you will need a bigger motor. This model uses a .46 glow, this size motor is reffered to in other models or brands as a .25. If you install this Turnigy motor, let us know how it turns out. It would be interesting.

 Pol81 16 points

No! Diameter of shaft: 5mm" means that you need prop adapter like "Prop adapter to suit 5.0mm motor shaft (collet) SKU: JY5.0" or spinner!

 Manuel 2 points

Thanks for reply. As I can see on the pictures there is such a prop adapter with. Right? Which dimension does it have?

 Pol81 16 points

Sorry but I already mixed with other adapters and I can't tell the exact size.

 marcolino 190 points

I've installed this motor on build for myself pilatus porter (3 kg and 3000 mAh 3s battery 60A ESC) and i've already flown with the 12x6, 13x8 but i'm not so happy (too slow), now i've bought a 12x12 and this WE a would like to test this configuration.

 Manuel 2 points

It depends on your application. for heavy octocopters 3-4kg 12x6 is best.

 leprosylv 24 points

D'apres un calculateur il faudrait entre 300 et 350W pour ton planeur. En prenant un moteur de ce type tu sur-dimensionne ta motorisation

 Karl Heinz 54 points

yes it is. take this www.link

 Karl Heinz 54 points

where is the link???? i hope you can see it www.link

 Karl Heinz 54 points

www.link

 Karl Heinz 54 points

hobbykinghomepage/electric motors/motorparts/ and the secondt page. its called: Turnigy Aerodrive SK3 3548 Series Replacement Shaft Set because the links make problems!!!

 marcolino 190 points

Thank you very much for the answare,
but the length (70 mm instead of 64 mm) and the seger position are not the same of the original.

 kizashi 55 points

This motor is usually refered as a .25 motor in many other brands. If you had a .40 OS my opinion is that you will need a bigger one. Maybe something with a 4250 denomination or a Turnigy G46.

 Karl Heinz 54 points

there are no problem! i fly the x8 with a 11x8 prop on 4s and there is no problem! take 2x 4s5000mah and the center of gravity is perfect. one at the front and the second behinde the strut.

 NewToHobbyKing 7065 points

So what is it?????? I am so sorry. Test Rest. OK you all agree I am stupid. I only comment on things I have done. Some work!!! Some are even BETTER than what the old guys tell me to do. I have a computer back ground. I find we make more advances through what does not work! It is the hunt for a different way. I can meter the motor and see if it is shorted to the body from the winding. Then what? I can cut the plugs off and spread the wires and meter the windings. But I thought of THAT and I would rather be out flying!!!

 waterlogged 2844 points

You don't know much about RC, yes I'll agree with that. But if that is the case, how come your previous ID you used for scamming you had 15,000 YES fifteen thousand point in 18 months and in less than 6 months you've collected over 3000 points. A newbie hasn't a chance of getting that many points legally. I actually caught you putting up your own points last week. Right before my eyes you score jumped 50 points and your reason was you were playing around withthem and suddenly they jumped up. By your own admission you don'y know that much about RC so explain how your points sre double mine and Sawdust when we aren't newbies and give good solid advice. Someone who doesn't know how to check a motor but by your own admission you have more than 5 planes and you don't count them. You did when you were Kellyann and told me 125 planes. And many more still in boxes. Tell me how do you manage to move from Brisbane to Sydney with 125 planes and all the RC gear you own. You must have rented at least a 3 bedroom house to store l those planes whilst being on the Dole. You told me you were looking after kids and yet you've been stuck on your computer every day all day. Funny in all this time I've never heard the new BS of knowing a lot about computers. Maybe you can help me with a problem I have. :-) You know what it is Kalyan AKA kellyann AKA NewToHobbyKing AKA Jasper AKA Kellyandog AKA kellyannharvay. All those names except the first two you yourself have given us in the last week The other two we already knew. You goose is cooked. You've done you dash, you're done like a dog's dinner. Now for the sake of this forum complete your promise of a few days ago when you said OK you've been caught and you'd had enough and were leaving. Just leave quietly and stop avoiding the inevitable.

 waterlogged 2844 points

I have to ask, since when is this motor so big. Has it been taking steroids? I'd hardly call it large. It's pretty common motor. Strange you wer telling a member he should use a 50 or even a 60 on it only today and yet you run the identical motor within an hour and burn out a 30 amp ESC Knowing it requires 40 amps minimum. Ithink you aren't just a liar but a drama queen too. Anything for sympathy is it?

 Ivan 6 points

fyi im using a 3s 5800 battery

 Karl Heinz 54 points

i flying this motor on my big X8 and it's great! 2x4s4000mah at the front and everything is fine. *) 11x6 prop and a hobbyking 60A esc. PERFECT!!!!

 nicholas c 1 points

Hey Karl, I just ordered this motor for my X8 and was going to use the same lipo setup as you,how far up front did you place them and flight time? Thanks.

 Ivan 6 points

what type esc your using ?

 nicholas c 1 points

I will be using a trust 70, I know it is overkil

 Karl Heinz 54 points

take a turnigy thrust 70A or plush 80A. how can i say,... go to the hobbyking homepage to the x8, and on the 4 picture. you can see there is one stiffening at the back - than a carbonpipe - and at the front a stiffening. take on lipo at the front from the frontstiffering and one lipo at the back from the frontstiffering. a gopro and the center of gravity must be good to flying. 3s is not so good for the x8. he have no power. at least 4s. 5s is very good. i know some guys they fly this motor on 6s but.... hmmmm

 NewToHobbyKing 7065 points

14 Magnets but WHY?

 Norbert1 62 points

because of how to rewind this motor, with 10 or 14 magnets you can use a special winding technik

 NewToHobbyKing 7065 points

So why do you need to rewind it if you do not have one? Also can you help me with mine. I crashed. When I hit the deck I got smoke!. I though I burnt out my motor. So I went to use the ESC and found out it was dead. So how can I check the motor?

 waterlogged 2844 points

Ignore this person Norbert. A complete fake. He is giving every true Pro Contributor a really bad name. He's been kicked of the forum twice and sneaks back with a fake ID and gives himself 3000 points. Last ID, Kellyann he gave himself 15,000 points. Ignore him. Actually this stinks of setup to me. He insists on knowing why you want to know how mant magnets and then says you don't own one. If you are going to rewind it wouldn't you pull it apart to do so and count the magnets then?

 Norbert1 62 points

When I pull it apart, then I see how many magnets are there, but first I´*ve to pay for. If it has 14 magnets, everything is fine - i not then I can´*t rewind it the way I will. Thats tge answer.

 waterlogged 2844 points

OK mate I just wondered that's all. Most people wouls simplt throw it away and buy a new one but I do know a friend who rewinds his own. They usually end up being faster than orginally but that's due to different amounts of windings. Good luck to you for getting them fixed. What does it cost to have it rewound?

 Karl Heinz 54 points

yes 14!

 jean-claude 49 points

why not. simple but good. choose your propeller does not exceed 40 A. cordially JC

 NewToHobbyKing 7065 points

Ok it is rated for max 40amp but if you have not bought your ESC Yet! I would go 60a Ecs. I find a little bigger, is a good margin. If you have the 40a Esc go for it. It will get hot and you will have to let it cool between flights. If you buy a 60a or 80a even, then it will last forever. (Well unless you crash like me). Yes bigger is better, but you can go too big. Like a 100 up, would be silly.

 jean-claude 49 points

I know people who use 3 condoms at the same time ..... for extra protection Cordialy jc

 Ivan 6 points

haha...

 waterlogged 2844 points

Depending on the prop mate, a 45 amp Turnigy ESC will do the job. If you do overprop it you may have to step up a little but I use 45 amp Turnigy Plush's and they have enough in reserve as long as you don't run them flat out all the time. 3 at a time JC. To be sure, to be sure, to be sure. Said the Irish lady of the street.

 Karl Heinz 54 points

3S*4S and 5S also!
I fly this motor with 4s and he is great!

but for this plan, i think on 3s3300mah and a 13x4 probeller must work!

 iPetePete 5 points

5.6 lb (2540 g) Sorry, the title had the weight, which doesn't show up anywhere ?

 Eeeeky 30 points

Hey there. In my opinion i would use a pack in the neighborhood of a 4s 5000 30-40C for a decent flight time, a little large, but if you want longevity you may have to sacrifice in the weight dept a little. Hope this helps! Post a video of this quadcopter, its going to be a dang beast!

 Andrew 1 points

I sure will for you! I just wanted to make sure with the battery..so I'll go with a 4s 5000mah 40c...so what's an estimated time of flight I would have for this? the motors have a 40amp max each so that times by 4 is 160amps..but I wouldn't be near full throttle..so if I was at half, pulling 80amps, what would the time be? just curious and can't figure it out myself

 Eeeeky 30 points

Its fairly hard to figure. Variables include altitude, temperature, humidity etc. With a 5000, id estimate between 10 and 15 mins. However, i could be completely wrong. ive got no experience with a motor this big on a quad.

 Pullsee 10 points

If the quad is drawing 80 amps then the time in the air is 3.75 minutes. 60min/(80A/5A)

 Eeeeky 30 points

Each motor pulls 40A at full throttle. So im assuming your saying the quad will fly at half throttle. Judging by my experience with this motor, it will around 1/4 throttle to fly. They are VERY powerful. If its loaded down, sure it will take more, but unloaded...No way.

 RattleSnake 392 points

Your assumptions on the power draw are all wrong. just because it is rated to 40amps max has NOTHING to do with how much it will draw in a setup. It has EVERYTHING to do with the battery and prop you use. This motor would easily handle more than 40 amps anyway.
