Turnigy 1811 brushless Outrunner 2900kv

I've got two sugestions, First: Calibrate ESC, you can learn how to do it everywhere, but it goes like this, turn on transmitter, throttle to MAX, turn on receiver ESC, etc. Wait for the bips, throttle to min, turn of the receiver and ESC. Second check if your propeller is the right way around, prop spec numbers (5x4 5x5etc) must be facing forward. I do not know what airplane you've got, but check the CG.

checked it. doesnt make a difference. The plane i got is the playmobil 5215 comparable with the HK swift. My esc is 10 amp ( HKESC10A )

I think it would be abit overkill. I put this motor in my telemicro and it just bullies my poor tele to submission.

DGHallal, You may be overloading it with a prop that's too large for this motor to turn. 5x3 is optimal and no prop bigger than 5in. Hope this helps and Happy flying!

Andriyan, This is the program card I use on practically all but a few ESCs. "PRODUCT ID: TR_PC". It works well with just about all programmable ESCs but was designed for the Plush.

Is 1811 not 1822

 RonRC 2113 points

Danos, It very much depends on your application of this motor... fixed wing, heli, multirotor? I use 3 of these on my little T-tricopter. Hope this helps and Happy flying!

 RonRC 2113 points

Here they are on my little tricopter.

 RonRC 2113 points

This was the maiden of this little tricopter.

RonRC, what props do you use?

 RonRC 2113 points

Drunya, I'm using 5x3x3 GemFan props. They are sold here as 5030 and 5030R props.

The grub screws are tiny so I think you'll find them difficult to replace. Thankfully the motor is small so you can glue the bits together with CA. It will hold.

 RonRC 2113 points

Terence, I've not done it on these "Yet", but on the little C10 motors I've replaced with larger screws by using a drill and tap. All can be done by hand using pliers. Hope this helps and Happy flying!

 aranfitz78 7 points

Yes, CA / loctite them in place.

Yeah, that'll work.

 Danos 17 points

Hi i have a 5x5 prop will fitting a 6x3 make much difference? Thanks

 __AD.. 18 points

I don't think you'll be needing too much power, I'd recommend the Turnigy Plush 6A ESCs

 RonRC 2113 points

I'm running 3 of these with 3 turnigy plush ESCs and my little soapbox tricopter flies wonderfully. I'm using a 1000mAh 2S 30C battery too.

 RonRC 2113 points

I took it outdoors for a maiden flight and crashed it... TWO times. Ha ha! It was easy to rebuild and it flies again.

 wesix 121 points

Yes, current draw on 5x3x3 is a tiny bit less than 6 amps at full throttle, thrust about 110 grams on a fresh 2s battery

The mounting holes are 17mm across (diameter)

Isso deve funcionar ok

You can try to put a flame under the wire to burn the coating and then use a sandpaper on the wire. Use flux or flux core wire when you solder.

Sometime you can try other kind of solder too like silver , it may work better.

 Tommy 11 points

i just got the wire soo short now i may have to splice it together.

 ohmgnohm 47 points

Burn the wires with fire....after take a sharp knife and scratch away the coating...after clean the wires with nitro..let it dry...now put flux on it an solder it again.....on this way i do it always and it works great

 mlp666 5 points

You could try using an active flux. Active flux uses an acid to clean and etch into the metal. Just make sure you clean the joint afterwards as the acid will still be active after you have soldered.

The motor to motor mount connection is fixed with 2 allen grub screws. They are ridiculously small and the size is for me still unclear (perhaps they're imperial). I bought a set of various tiny allen keys and I can tell you that the 0.75mm, 0.9mm, 1.2mm all don't fit. I ended up using a star drive which did the job. My advice, buy a kit with many different tiny drivers and just use the one that fits the best. You can't use much force (torque) otherwise you'll break them, so just nip them up, a good fitting flat head will also do the job. You need to use CA to fix them anyway.

 CrashAce 810 points

they are 17mm across the hole diameter looks like 1.5mm. 2.5mm will not work there is not enough material to enlarge them that much. I used some spare servo mounting screws for mine.

 aranfitz78 7 points

Thanks anyway CrashAce, but I bought M2.5 bolts and they definitely fit, M3 however would not fit. M2 would also fit fine. Perhaps there are different versions... but I have a mix of new and old and they are the same.

 wesix 121 points

mount holes definitely are M2.5

 CrashAce 810 points

I purchased mine more than a year ago, must be using a different mounting plate now.

 wesix 121 points

i'm wrong, these wholes are in fact m2 size.

 CrashAce 810 points

Everything (or just about) you buy from HK is metric. You need a 1mm hex for this one.

 FrankPo 9 points

On my engine their are two different size screws. The big one is 1.3 mm Hex the small one in 0.9 mm Hex.

 robopony 19 points

The bigger set screw (holding the motor in the mount) is SAE .050 and the smaller one (holding the bell to the shaft) is SAE .035.

 CrashAce 810 points

Are you using the spinner that came with the motor? It's surprising that a 5x3 doesn't fit. You could try to find a different 2mm prop adapter with a longer threaded length, or (against better advice)if the propeller hub is wide enough you could counter sink the hub or just sand it down a bit just enough to thread it about 3 turns.

 Joao 13 points

Hello Ender22, advise you to use a 1.8mm-2mm drill to open the 5030 props axis and then force the prop into the shaft, WHITHOUT the hub. You save weight and complication. You can ever over those drills/mills here. Regards,

 CrashAce 810 points

I responded to you question with quite a bit of detail but for some reason my answer was deleted. Yes, This motor should workout well. The Bonzai calls for a 5x3 prop and this motor can handle up to 6x3. Your fine to use the Bonzai recommend 5X3 or for additional speed HobbyKing has a 5x5 that should work. For additional thrust you could try a 5x3x3 (three blade, but currently out-of-stock). stick with the Bonzai recommended battery size to avoid CoG or wing loading issues.

 Ramon 9 points

Thank you for uploading that, but do you also have a comparison between props (specifically the 3 bladed vs 2 bladed 5030's)

 avi@tor 29 points

Dear HK, why does this motor comes without electrical specifications? Do you actually realise that it is impossible to make any calculations without knowing Resistance and No-load current of this motor? Also specifying magnet pole count would be very nice. You have done so much since I first attend this store, don't stop now, be professional.

 CrashAce 810 points

It's a 2mm shaft. I bought a prop adapter separate but found that it is included with the motor. So now I have an extra. Yes! The prop adapter comes with it!

 Matias 5 points

I ordered one.. it' s beautifully made and safely boxed (which is great: here in Italy they tend to BEND and TWIST fragile packages easily) and i had a nice surprise!! It comes with everything to connect it!! (connectors, prop adapter,even shrink tube!!) you only need to add a prop of your choice!!

 Fannaticc 6 points

has anyone used these motors with a 3s pack? I currently am using a 2s pack, they do get a bit warm, but I am needing a bit more punch. A little expensive, fragile bearings

 TechnoFinder 126 points

i tryed on the quadCopter...lmy experience is it s getting too hot for 3s.

 ohmgnohm 47 points

I use them in my 2 micro Quads..... 5x3 Prop...and 3s 1000mA Lipo. The motors get normal temperature :-D so nooo problem at all. I just change the motorplate support. Just drill out the hohle in the support...and change the motor to the other side.....so u get less fibrations on the motor.

 BrianB192 1298 points

it is the larger of the smaller ,,but very well made ..do you want a measurement with vernier ,i can give you that ,,but i do see its well made large enough ,and good size not to large to out balance it .

 TechnoFinder 126 points

1.5 mm ?

 Syamil17 24 points

If thats the size then i will need to buy a hexdriver. Thanks. I needed to know that because i was thinking of pushing the shaft the other end for my lama v4.
