Correct Sir

Well tried the 2S lipo with this setup. Hover at 80% throttle so no good! Use 3S lipo now and all oke!

3 cell this motor screams !!!!!!!!

I have mine on a home built flying wing and it will do 90mph easy !!!!!

What size and make prop?

 Alistair 22 points

Yes. It flys very good with this motor.

 somchai6813 170 points

Yes, confirmed...It suite really great. Great choice for walkera master cp.

 somchai6813 170 points

Best fit. Using the pinion fromoriginal brushed motor. Work well, Fly fun don't worry sbout the pitch pump.Superb.

The timing mode should normally be "high" since this is an outrunner. Try that one first, if the motor or ESC gets hot then try "low" or "automatic" (don't run it too long). I mainly use two throttle/pitch setups: Normal, where throttle is 0-25-50-60-70, pitch 47-48-50-60-70 (for take-off and landing). Idle up 1, where throttle is 80-75-70-75-80 and pitch is 20-35-50-65-80 for 3D/inverted flight (50 is zero pitch). Your observation is correct, the motor must run for the tail to run. If you lose power while in the air, only the main rotor will continue spinning (provided that the bearing friction is low enough). In general, this size heli is not really up for auto-rotation (but there is a guy on you-tube that does it with a t r e x 250). But this heli has no drive of the tail rotor when auto-rotating, which makes it even trickier I guess (haven't tried it). HTH

Thanks for taking the time to answer the questions. Much apprieciated.

I have this motor in both my HK-250GT, and I love it. I'm using it with Turnigy Plush 25A ESC, Gaui 15T pinion (for 2.3mm shaft) and Turnigy nano-tech 3S 850mAh batteries. The battery gets a little warm, but nothing to worry about. Hope this helps..

it ill handle any esc 15 to 30 amp appropreat battery is 2 to 3 cell lipo 7.4 to 11.1 volt up to 2600 mah and no mor than 30c what elce do you need to know all the info is writen with the description such as size its desighned for small load especialy if you choos a high powerd esc to run it

 450 trex 103 points

theres nothing we can do about how long it takes for HK to restock contact the support center

 Sebastian_Hely 45 points

Yes, I remember 2 pinions, one 12T and one 15T. I recomend the 12T.

 Dubsounds 14 points

Between the two pinions I actually recommend the 15T but don't forget to use a good set of blades like carbon fibre ones... never plastic ones... I think that greater headspeed gives a better hover on a small heli *)

 oyvindbjo 7 points

No. The pinions don't fit HK250, the spacing between the teeth is to large. And the pinions supplied with the HK250 does not fit this motor. The shaft diameter is 2.3mm(not 2mm as stated above), while pinion of HK250 is 2.5mm.

 Dubsounds 14 points

Exactly the pinions that came with this motor can NOT be used with a HK250 because they are too tall. But you should use the 2.3mm pinion (0.4MOD) not the 2.5mm(0.4M). That would cause unbalance and vibration. Check the firefox section for 2.3mm pinions for hk250.

 christian 41 points

Hello new to helis can you link the item number for the pinion :) thanks.

 Dubsounds 14 points

No man... search... because links are not allowed, go to the slide bar, helis, firefox and pinions with 2.3mm hole and 0.4M and your done

brushless motors are measued in KV meaning RPM PER 1VOLT thay dont have an armature with turns in this dase the sharft is the magnet and its turned by alternating current in coils of wire mounted to the can of the motor thats just a simple way of explaning it so in this case the motor has a top KV rate of 3800 and lets say you run it on 6 volts for example youll get 3800x6=22800 RPM also in respect to these motors KV dose not mean killervolts its a common mistake to beleave this it simply means

 RCswe 14 points

kv * volt = rpm (turns)

example if you run this motor(3800kv)on a 2s battery (7.4v) you get

3800 * 7.4 = 28120 turns

Haven't used in funjet but I am running it in my homemade F-4 pusher jet, using GWS motor mount, 1300mah 3s, 25A ESC, APC 4.1X4.1 prop. AUW ~420g (15oz), lot of power, good vertical and speed. Well made motor for pusher jet.

 solentlife 117 points

This will be going into my Parkjet replacing the heavier 450 heli motor I have. For Funjet should be a blast !

 450 trex 103 points

with an 11.1volt battery and the motor running full potential the total rpm is*42180 the formula for brushless motor rpm is kv x voltage so 3800kv or rpm per volt x 11.1 volt battery gives you the anser above if you use a smaller or larger voltage youll get different rpm this motor can handle up to 6cell battery with the appropriate esc of 60-80amp

if possible it would be best to write in english that way we can all help you my computer dose not have a good translater sorry

 Turbobeaver 1336 points

Google Translation: What is the final speed of the motor, an aza zaggi 90cm?

 450 trex 103 points

iv also bent the sharft in one of these motors whats requierd is to remove the E clip and grub screw anseperate the motor case and rotor than position the can over a vice an with a light hammer and small punch tap the sharft out of the can though must be carefull not to dammage anything its probably a better idea to get a new motor LOL

 VirtualCowboy 20 points

Where can I get another shaft for it? I tried local hobby shop, but they said it would have to come from motor manufacturer. I tried ordering a similar shaft from HK also, but may be a backorder holding things up.

 450 trex 103 points

This motor dose seem to be an unfortunant topic lol iv tryed ebay and my hobby shop with no luck what you could try is buy a length or steel rod/shaft from your local hobby shop or hardwear stor maybe a local metal shop or bearing shop i bought a new motor when i stuffed mine but sometimes i just make my own parts

 solentlife 117 points

 EDWARD 71 points

Yes it comes with 3.5mm connectors for both ESC and motor.

 Aureo 18 points

What another motor to use in heli hk 250, or this is good? I intend higher time of fly, Í* don´*t fly 3d, I´*m learning to fly yet. Is there any motor that cames with pinion that fit at maingear of heli hk 250? What?

 some12love 8 points

use the pinion that come with the 250 kit because i used that with the same motor and it working fine...but this motor will running on a 3s battery and you want to run on 2s battery then you have to a motor from firefox part page on hk...hope this will help you..

 LasseK 564 points

Hi Aureo! I use this motor: T2627-3800, and I use this pinion: E2.3-0.4-14T. You have to cut off a few millimeters of the motor shaft but that's easy. Look under the Files section here for "HK250GT FBL Build and setup" for details.

 EDWARD 71 points

The 3mm shaft is the same as many other motors in HK. According to my experience, any 3mm shaft should work fine with this motor* but I am having hard time pushing the shaft out of the bell, whereas many other 3mm, 3.17, or 4mm shaft are fairly straightforward to get out. Think this motor might work best as the bell hanging at the opposite side to the prop* you need a motor mount like the GWS type (HK product ID: GWEMM28TS) to mount the motor. Hope this helps!

 EDWARD 71 points

Your setup sounds good. Of course higher C rating battery would be better and 30A ESC would suffice. Motor shaft can be loosened with allen's wrench and repositioned as you desire. make sure to use or make a flat spot on the shaft where you tighten the set screw, lightly filing would be enough. I routinely replace shaft when I received a new motor.

 Dimitris 11 points

go to a hardware store with the shaft an tell them to give you a bolt same size i thing it is M3 it works

 adlers83 295 points

I think it don`t work. The shaft has on the one end 3mm and on the other end 2,3mm. Why Hobbyking don`t have replacement shafts for this motor?

 Dimitris 11 points

yes for most trex clones

 Dimitris 11 points

yes ok

 Dimitris 11 points

yes i does

 emirian 5 points

yes but use 4 x 4 prop not more

 Trexter67 1 points

Ok thank you and I am using this set up for the NQD jet boat upgrade

 mmela1 2 points

Yes You can , as you can check from motor spec ,the max Power value is 260 W , this means that if you use a 3s battery you can have at maximum value of current (I=W/V) aprox 260/11.1 = 23,4 Amper MAX. So you ca use the 30A ESC whit no problem BY
