You can't. If you are looking for a motor that only has 2 wires you need to look at Brushed motors. Search for Brushed and look through the results.

Have it in my Vampire mated to a 4-blade EDF unit (which is not sold anymore???!!!). Takes around 800W on 4S and gives good thrust and speed. But I wouldn't recommend running full throttle all the time, the motor does get quite hot.

 icourier19 3 points

Hi, it does not matter. Just connect them in any order. If the motor runs backwards when you do this just swap 2 of the wires, any 2 then it will run forwards. Hope this helps, Ian.

 dhruvafreak 530 points

yeah , you just need to connect all the three wires to the 3 motor wires and if you want to reverse the direction of the motor just take out 2 wires and interchange that connection and you are good to go

the bearings in this motor are worthless. dont waste your money.

 FireHawx 81 points

Mine burned on second flight. My 2836 2350kv is great though.

i used a 3mm adapter for the back and it was very secure

 Michele 3 points

4mm at the back end and 3.17mm at the front end

Thx guys, MUCH appreciated. Unfortunately again two opposing answers, 3mm or 4mm? Are there that different versions of this motor available? I would appreciate if more of those who recently purchased this motor could respond Thx a lot again!

 Funprise 415 points

I think this is similar to the typhoon motors its a step shaft where in the shaft were it is inserted unto the motor is 3mm and the shaft where it portrudes outside is 3.17 mm. They do this since most pinions for 450 size heli is 3.17 mm but its easier to get 3mm bearings for the case.

 StevenC 556 points

It really does not how you plug them. If the motor spins in the wrong direction, just swap 2 of them and your heli is ready to go.

1 for steven

 lembios 16 points

Connect occasion in any order. In the case of rotation in the opposite direction, any two wires are reversed.

 Vassili80 141 points

Yes,I use a hk 40amp esc and it is fine.

 StevenC 556 points

In my opinion 35A is not enough and the ESC might just fry. I think 40A is the minimum, but 45-50A would be best.

 Diximus 5 points

I use a turnigy 80amp esc with 4.7 x 4.7 is beautiful for plane!

 __BIMS 13 points

I used Turnigy AE-45A ESC rated for 45A but still the esc's temp cut of in flight. I crashed twice not knowing that. better to go for a higher amp ESC maybe 60A would do. This is a really good motor.

 MarceloMMY 93 points

I recomend you use at least 50A ESC. This motor is very strong.

 wildthawn 240 points

it really depends on your use of it i use a 90-100 amp esc but im using it in funjet and things of that nature so i need the extra ump to get blazing fast speeds with a small prop (4.75 x 4.75 or a 5x5) depending on your pinion and main gear i think a 50 amp would be good for a 450 size heli

 Daniel2000 50 points

I got this motor in my T-rex 450 2 years ago and it is still running great! I got 70 mph out of my 450 with this, I use a Kforce 40A ESC with a 11T pinion, and I got plenty of power, maybe not for hard 3D but I haven't reach the level to fly hard 3D anyway

 Vassili80 141 points

hi. Use 3mm screws,but ceck for the lenght or them will destroy the winding inside the motor. Also you have to enlarge the slots of the motor mount.(hk450pro)

 psguardian 33 points

3mm x what? What is thread pitch & count? If used with hk450 motor mount plate how long do the screws need to be?

 Vassili80 141 points

metric m3 . 6-7 mm long but ceck for the right lenght,if too long will damage the motor.

 Vassili80 141 points

Thank you for the credit.

 icourier19 3 points

I have this motor and I used the stock screws from a Belt CPX, they fit perfect and no need to widen the mounting holes.

 StevenC 556 points

Yes it is compatible with 450V2. The pinion size you need will depend on your type of flying. If you are still learning you would need a 10 or 11T. For sport flying 12T, and for 3D you will need 13T.

 johndoe81 21 points

Great motor I have in a HK 450 pro. The motor is perfect.

 Rothmans 1377 points

Yes, it is enough strong and suit for 450.

 rcflyertim 124 points

You have to watch the temp on this motor. It does not like to go over 550 watts or it starts getting hot.

 StevenC 556 points

It's a powerful motor and perfect for 3D. Must be used with strong blades like glass fibre or carbon.

 Javier 1 points

No Tony! This fits perfecto for 450 Heli!

 NICOMONI 7 points

This is the best option

 Eva 6 points

This engine is strong, but needs the hard-pol and a good ESC that you get the most from it

 rcflyertim 124 points

Any of the Axi shafts will work or you can also make one if you have a lathe.

 wildthawn 240 points

i make mine outta harden nails or a car antena that is solid steel i have found its a common size and a lot of things can be reperposed to make one

 Rothmans 1377 points

This is a High Power and High KV motor. So you have to select the maximum 26.25 degree to get the high performance of you motor.
Anyway after changing the timing setting ,please tesr your RC model on ground perior to flight.

 pigeon 4 points

Thank you. This is for maximum performance. What is the timing value set if I want to get the minimum noise and vibration?

 Rothmans 1377 points

Where do you install this motor(heli or plane)? what prop are you using? I'm not sure what mean you noise and vibration come from..

 pigeon 4 points

I use this motor on my T-Rex 450 heli with 3S Li-Po and ESC Hobbywing Platinum-40A-PRO.

 MarceloMMY 93 points

Yes it has a 3mm shaft.

 Rothmans 1377 points

The diameter of shaft is 3.17mm.

 Aleksei 7 points

I have the same motor. Shaft is 3.17 mm.

 mad jay 184 points

cheerz guys

 morphine 407 points

What ESC will you be using? This makes 88A on my skyfun and I run the HK 90-100A ESC at its default timing setting whatever that is.

 fireman77 1 points

I'm using that motor in my 450GT, and run it at 16KHz

 Vassil 13 points

I'm using Turnigy SuperBrain 60A on my HK 450. I know the frequency should be set depending on the motor impedance, does it?

 fireman77 1 points

I'm using 40A HK BESC and acording to the manual outrunners should be set to 16KHz. Timing is set to Auto. Using the Turnigy 2.2 battery

 Brheli 158 points

qith a 40A ESC 12Hz, Medium, moore than it the motos will vibrate

 StevenC 556 points

You can determine the best frequency by using this formula, PWM = KV x Voltage x Poles / 20. Since this motor has 6 poles, PWM = 3700*11.1*6/20 = 12Khz

 Vassil 13 points

Why it is dividing on 20?

 StevenC 556 points

The 20 is just a constant.

 Vassil 13 points

What is the meaning of this constant?

 StevenC 556 points

I'm not sure but it is just a constant value, and it does not depend on the hardware characteristics. At least for us users www.link

 Vassil 13 points

Okay, let's think. KV x Voltage is the maximal RPM for that voltage. => Max. RPM x Poles / 20* If the switching frequency of each pole is Max. RPM [Hz] - the rotor will rotate with that speed, because the motor is a synchronous motor. So each impulse per pole is cut internally on Poles/20 pieces. I think Poles/20 is a good ratio to cut each impulse for smooth enough rotation. But higher is better I think, except the resistance of the motor. I think dynamic resistance is the way to choose good frequency.

 2Doggs 186 points

I've found that using 16kHz gives smoother running at part throttle than 12 or 8kHz, with a Turnigy SB 40A and Typhoon 2218H & 2215H motors. (both 6 pole motors)The downside is supposed to be slightly higher ESC temperature.

 aka 11 18 points

no not come with esc

 maq007 9 points

The 2836 is a nice motor with plenty of power. It works well with the HK450's and requires a 40a ESC. Several are available at HobbyKing that will be appropriate. Maq

 Sergey 2 points

no its not com with esc you have to bay separaete. motor is perfect

 Heartstarter 18 points

You'll need a couple of screw similar to those in computer DVD drive mounts. You'll also need to file the motor mount in the Pro kit as the slots are not wide enough for the larger diamter screws.

 l0lz3r 11 points

It is your choise. But for me best is Mystery 40A Brushless Speed Controller (Blue Series) .

 Carlos Baroni 3 points

Para helicoptero 40A é o suficiente Para Asa ou funjet tem que usar acima de 70A para não esquentar.

 morphine 407 points

depends on your application. I am running it on a skyfunjet on 4s with a 4.1x4.1 prop pulling 88A at WOT.

 Heartstarter 18 points

Turnigy 40A Plush works fine. Never gets hots with 13 tooth pinion.

 Budai 1 points

it seems that the distances between the center of the holes are 16x19 mm. Beware though you need two types of screws 2,5/3 mm thick and 6 mm long.

 Brheli 158 points

HEy they are good enough to 3d but you shold buy something better if you wante a safe heli

 keronc 53 points

Hello, When I used the 2836 3700 on my HK450 heli wit 11t pinion it was so powerful that I had to limit my throttle to 60pcnt or the vibration would make the heli unstable.

 maq007 9 points

Funprise, go to forum and type HK450 and look for post from Ivan. He uses this motor and has a lot of videos. In fact they are all he uses. One of his threads is building a 8.95 3d heli. He does all sorts of things with them and is very nice and easy to ask questions of. Send him a PM for the best recommend on this motor. I'm sure you'll get the answers you need. He says he files a flat spot, and I think he is using a 12 pinion. But watch the videos and ask him! HOpe this helps... Maq

30?- 3cell, current 400 watt. 700 watt- 4cell.

 Brheli 158 points

For a 450 Heli you need a 40 A esc with a 30 A esc you will use this motor in a 250 with out problems

 morphine 407 points

1100 watts 88A on 4s with 4.1X4.1 prop on my skyfun. Its a great little motor. Stupid power!

 Michael 28 points

I'm looking at this motor for a HK parkjet delta pusher...specs on this motor are 30a...how is it that you're not blowing the motor apart pushing 88a?

 morphine 407 points

Michael I dont know why this motor holds up so well. It is a very good motor and I have abused mine over and over and over. It is very robust and the specs are definately wrong. Buy it before the Chinese New Year chokes Hobbyking and delays orders. You will not be disappointed in this motor at all. If you intend to put it in the RadJet or the SkyFun (delta)it is an excellent choice.

 Michael 28 points

Sounds good, I take it you're running 40c batteries, I have Zippy 2200 4s 40c batteries (50c) burst...what's your opinion on these puffing under these draws?

 morphine 407 points

I ran a Blue Lipo 2650 4s and 45C (Still have that battery and still use it.). I had a run of bad luck with Zippy lipos and Blue Lipos and abandoned those brands for Sky Lipo and GensAce, but everybody has their favorites, and eventually all my batteries get puffy no matter the brand, but the GensAce are outperforming everything else I have tried. I am running my first Turnigy Nano Tech with high C ratings this season and will see how they perform. In a nutshell Michael, always run more battery than your system will draw. If I had a draw of 80A I would consider a battery like this. 2200 50C (Not the burst rating)or higher C rating to safely draw those kind of Amps and have a nice cushion to keep my battery safe.

 Brheli 158 points

It isn't a airplane motor this is a heli motor but if you want to adapt it's up to you

 ariete 5 points

It is offered as combo price by HK in the pylon model (see product ESPPEED25EPKIT at sport ... model airplane section)

Tenho esse motor em 01 skyfun e 01 Spyner Cat,ficou excelente nos 02 avioes,motor nervoso e rapido,estou pensando em colocar tambem em 01 Falcon. Recomendo com certeza Luiz

 morphine 407 points

4.1 X 4.1 I use it on my SkyFun.

 morphine 407 points

Thanks for the credit. I recommend the BEC Opto HK 90-100A ESC. I think my skyfun pulls 88A at WOT.

 morphine 407 points

Turnigy AerodriveXp 28-36 SK Series Shaft This is what I ordered for this exact motor so I could go to 4mm for strength. It should come as no surprise to you that it is not in stock right now.

 RattleSnake 357 points

I replaced mine with a shaft from a Turnigy SK 3536. Worked fine, I prefer it with a 4mm shaft.

Im pretty sure that any 4m shaft will work as long as its long enough.

 morphine 407 points

Its WARNING...........

 Brheli 158 points

You can report it to the suport.v and they may send you the missing items, for free.. don't worry it happens

 ekkeric 22 points

i did try both of the motor , and both of them was use it on the v2 mini titan , i still prefer this motor , after testing both of them , motor will get warm on each motor , but one of mine of the typhoon motor , the air vent was break after a few normal flight .

 Brheli 158 points

this one is berret, on it`s shape there is more space to the air courrent so it don`t get hotter as the others...and this one comes with the connectors that helps a lot

 o1hoegetter 1614 points

you guys speak english please so everyone know what your saying.. bueno?

 Meinschein 13 points

é compativel.

 GLEYDSON 2 points

sim, ele suporta mas nao aconselho, prefiro os de 50A tem menor risco de queima.

 Brheli 158 points

yes, it work`s but you should try with a 50 Ampers EESC because this mortor is to strong for it

 o1hoegetter 1614 points

this motor will burn up a 40a esc you should run a 60a or better.. i run a 90/100 hk esc just for the insurance
