Turnigy 450 H2218 Brushless outrunner 2500KV

I'm using mine on mid timing, on a 4s setup in my 450, and it gives plenty of power - better than a Typhoon 2218H on 3s, and only gets warm.

I've never actually bothered to change that function - I'm guessing the only need to alter is for smoother throttle response and is really only necessary for quadcopters

Use this formula. PWM = (KV x Poles x Voltage)/20. This motor has 8 poles. Therefore the best PWM will be 14.8Khz. The closest is 16khz!

As far as I understand is this the current specified for the max. voltage, which is 4S. this means that you can go with a 60A esc, but even a 50A esc is sufficient. I use it in a HK450 heli with 3S setup with a 40A HK blue series controller. But anyway, you can use the 70A esc as well, it only has a little bit more weight.

On 4s, you won't be pulling so many amps. I'm running this with a Hobbywing Platinum Pro 40A ESC in a 4s setup on an HK 450 Pro, and everything is staying really cool. (<40c) Seems to give a bit more power than a Typhoon 2215H that I've also used in both 3s and 4s setups on my 450 Pros.

Alguem sabe se fica bom esse motor ne uma zagi de combate de 90cm ou 80 cm com helice 5x5e esc 40 tgs Lipo de 2200 3s ?

Anyone know if this engine is good ne a Zagi combat 90cm or 80 cm with helice 5x5e TGS 40 esc 2200 3s Lipo?

tenho um motor deste em uma zai de 1 metro com helice 5x5, bateria 3s2200. Muito barulho e pouca velocidade mas talveiz em uma zagi menor va melhor.

To mount it u have to make simple plywood firewall and use prop saver or spinner

 Funprise 415 points

This motor can be used on heli 480 size with 4s setup i think if you do use this for fixed wing it would be a heck of a fast fixed wing with small prop

 bob shark 18 points

It's not a problem to install the engine on the firewall. On the front cover M3 screw holes. I use it with 3.17 mm. prop saiver and 7x6E prop and 50-65A. SSESC

in mijn aoto op 2s loopt ie heel hard en dan rij ik driekwartier op 3s gaat ie nog veel harder aleen veel minder zuinig 4s moet ik nog broberen het is egt een top motor en ook heel sterk

 bob shark 18 points

Your question is not so clear.
You can load this motor up to 500W.
Now about the rotation speed-3S=2500x12.4V=31000rpm
3S (10-12.4V)2500x10V=25000rpm.
4S (13.2-16.5V) 2500x13.2=33000rpm, 16.5Vx2500=41250rpm.
Good luck.

The pictures are dark but it appears the wires come out the back. Which works in my funjet pusher but my easy start mount holds the can.

Thank brutus315

 danikronos 660 points

this motor for the helicopters, too high speed ,enough for you to 1400kv

 jaiheat 38 points

I had reverse the saft some weeks ago. It is working fine...but now nothing keep the rotor and the stator together* only the magnetism of the magnets and the pressure of the propeller. If the propeller is installed in the wrong way or the saft turn reverse the can and the propeller will go backwards. Thanks

I'm putting this motor on a flat wing foamy F-22 pusher jet. With a 50 amp speed control and an apc 6-5.5 prop. With an all up weight,with a 2200 3 cell battery, of 24 oz. it has the high rpm to spin a small prop. Reversing the black and red wires between the speed control and motor will reverse the motor rotation.

 Brutus315 26 points

danikronos, I run a 2200 kv in my foamy easy star and 2700kv in my fun jet. I'm putting a Turnigy Typhoon model 2218 with appx. 3450 kv in my HK450GT,same as in my other 400 size heli. For the most part I think a lot of motors work well in different applications. I am no Electrical Engineer.They know best. Funny my Typhoon had a similar part Also notice that Turnigy has a series of 450 H2218 all the way to 3550kv

 Brutus315 26 points

jailheat, you asked this a while ago. I don't want to insult your intelligence but did you put the "C" clip back on the new end. They are super small and if you blink you miss it. It goes in a groove right above the bearing on the original shaft side. There are acctually you tubes and tools. I assume you got the grub screw on opposite side. RC cars have dozens of C clips ugg

 jaiheat 38 points

To put the C clip at the end of the shaft I should make a a groove. But, as the shaft is milled from 4 mm (for fitting in the two 4mm bearing) to 3.17mm I don't have enough place in the shatf to do this modification. The grub screw cannot be installed at the end of the shsft: here is a bearing

 Brutus315 26 points

Some people completely remove the shaft and install reversed so they can use C clip and grub. Thought maybe that was a possibility. Cheers good flyin

 o1hoegetter 1614 points

brutus315 what funjet are you running this in and how fast does it push it with what set up if you dont mind me asking im thinking about getting a real funjet from a diff. supplier and was wondering what set up to go with

 Dongskie 227 points

Sorry I didn'y see the bottom Line: "Recommended ESC" lol

My mistake :p

 Wilhelm 255 points

The Amps of the ESC depend on what you will do with the motor. If you just pull 20A you don't need a 40A ESC. Pulling 40A constant you might be in need of a 50A ESC. Wilhelm

 Pichi_Arg 24 points

I be waiting for one of this motor, suposse that in a few days arrive to my house and will can tell you if it possible....

 cleansurf2 388 points

Any success in reversing the shaft to make this a pusher ?

 Wilhelm 255 points

They put the shaft in there so you must be able to put it 10mm wider in. Unlock the grubscrew an push it through. But you might need a small ring with grub screws on the back to hold the shaft. Wilhelm

I was reading where the 2233-2900 at 16v puts out 2100kv and the 2233-2500 at 16v puts out 41,000. Ok, which motor would be best for a rc boat at 22" on 3S. They say the 2900 is really a 2100kv and the 2500 puts out 2600kv. I run 3S lipos. Power on 2500 is 500 watts and the 2900 is 600 but at 4S, so which would be BEST. Best to read the 2900 review. I generally run lower kv and higher voltage to keep things cooler and efficient.Oh yes, thanks.
