Eu uso e funciona perfeitamente!!!! 3S 3300 mah45c esc 40a.

 kslum 12 points

I use in BD-5, 6 blade, 4s, 50A ESC, the motor seem like very load and the magnet cracked. I suggest to use 5 blade 64mm

 adrianc 20 points

Thanks kslum, I'll give it a go.

 Milan 14 points

you can buy it in a set with 45a brushless contoller and 64mm 5blade Impeller for around 40 dollars

 Lukasz 13 points

You cannot use a prop. This is made for jets weighing around the 25oz mark with 64mm ducted fans.

 Straight Up 754 points

You definitely CAN use a prop! I wouldn't go 4S though - the prop will be scary small. How much power do you want? An APC 4.1x4.1 will give 400W on 3S.

Hey I am going to use this with a 5 blade 64mm fan and a 4s 1800mah 65 to 130 c lipo and a 40 amp ESC. I am going to use this set up in a stinger 64. Does anyone think this will work well?

 nickoedff18 36 points

I used it in a f18, with a 5 blade on 4s 2200 nanotech, with 45a esc. Speed was great, but motor only lasted a handful of flights, installed a new motor which died after only 3 flights....good power but don't count on it for reliability!

 _Yuriy_ 13 points

I can only confirm the grievous results. Bench rests with 5 blade edf (ID: HKEDF64), esc plush 60, 4s. Gradually pushed the thrust control stick of my TX. At the edge of about 750g thrust and 45A sound suddenly changed accompanied with the burst of smell of something melted. After this incident it can still work but with greatly spoiled efficiency I think. Hardly doubt that it can be used any more. So this motor is not rubust. Using it on 4s is waste of money. While my friend uses the same kind of motor but 3500kv on 3s and get a lot of fun for many months without failures.

 _Yuriy_ 13 points

I have to correct myself: there was 35A, not 45 when my motor boasted about what an amazing smell it can produce!

 Newfly 12 points

Hey everyone. I'm hoping some of you may have some advice for me. I use this motor in my original Stinger 64 with a five blade unit and a 4s 1800 mah lipo. The following has happened to me a few times now with this jet and it is pilot error..... In mid turn It does a little flutter and nose dives into the ground. The first time it happened I was using the rudder only. The second time it happened I tried to bank and yank with the same sad result. It does not happen every time I turn but rather seems to be completely random. Just when I think I'm getting good disaster strikes. This is my only jet and my only plane that behaves this way. Thanks :-)

 Straight Up 754 points

It sounds like a high-speed stall. Most people think a wing can only stall at low speed. However, if you look at a lift vs angle-of-attack plot for ANY airfoil you will see the lift coefficient drop rapidly anywhere from 10-15deg AOA. It's too much AOA that causes a stall. Try not to pull too hard in turns and carry a bit more speed to reduce the AOA. All too often I see beginners pulling crazy hard during turns, and this is the typical result with a high performance plane. Well done for seeking help. Best of luck.

 Newfly 12 points

Thanks I'll try longer turns. This is supposed to be a very capable acrobatic model and I was doing rather large turns when this happened. I will keep your advice in mind the next time I fly the Stinger 64. Thanks Straight Up.

 nickoedff18 36 points

Sounds to me like a wing is warped or bent, maby glued on slightly at a different angle. I had a similar problem with a global hawk, every time I turned left, it went into a spiral straight into the ground!

 Newfly 12 points

Thanks man, I'll check the wing. I hope your global hawk is flying better (-:

 Milan 14 points

what ducted fan do you use?

 Giovani 11 points

64mm 5 blade

 nickoedff18 36 points

me too, seems like a good combo, i am using this motor with 45a turnigy trust esc in my f18 nice speed and good vertical, not breaking any speed reords, but it has been a relible motor so far

 Newfly 12 points

What battery are you using for this set up Nickoedff18?

 nickoedff18 36 points

2200 4s 35c nanotech, motor died just after I placed this comment, installed new motor which lasted only 3 flights. Amps/watts were under max recommended due to throttle restricted on tx, must have got 2 dodgy motors, good luck!

 _Yuriy_ 13 points

Maybe those lucky pilots use 3500kv motor with 5blade edf and 4s? Because my 3800kv motor died instantly at full throttle with 5blades and 4s.

 Kent 19 points

Yes! you can use 3 or 4 cell. I use 4 cell on my JeTiger.. Works fine :o)

 ATX10 30 points

Any one with this same set up or close? 50 Esc, 6 blade Edf and this hk2836 3800 kv motor, what battery would work well with out burning the motor? Thanks!

 bill987 11 points

I use a 1800 4s. Great

 nickoedff18 36 points

use 5 blade and a 2200 nano-tech

 papatt74 16 points

Hi, this motor can only bear 35A for 60 seconds. On 4S with a four blade 64mm fan, the motor is realy hot and pulls 35 amps, so I think a 40A is enough.

 rabba 17 points

Pretty much identical the higher the kv the higher the rpm

 blazer1 82 points

If you wanna run 4s..go with the 3500..I've had both and the 3500 does it well with a 5 blade fan..the 3800 I had burned out on the 4th flight.

 Discus2a 80 points

Thanks! What amount of watts did you get out of the 3500 using the 5 fan blade and 4S? Any idea of thrust in grams?

 blazer1 82 points

if I remember right, it was about 540 watts. Something like 38 amps or so. I had it in my maxjet f/a-18 and it was just about unlimited, but have since gone with the aluminum unit. A buddy of mine now has the 3500 setup..

 Discus2a 80 points

Alright thanks! I'm still thinking of what to do. I've got a couple of options* Stock 64mm 5 blade EDF Turnigy 2815 EDF Outrunner 4800kv for 55/64mm at 3S. Orrrrrrr the Cyclone Power Turbojet 64 CS450-4500-30EDF (pw-rc ****) at 3S or 4S. Last option is way more expensive of course, even more expensive than the plane originally was. LOL!

 -MLG- 393 points

I use 7 blade HK EDF with 3s lipo And it works on the limit if you have on the full throttle.

 blazer1 82 points

Limit the amps drawn..I've burned one of these up with a 6 blade 64mm fan on 4s..3800 kv on 3s is going to have you running full throttle and pulling high amps on a 70mm fan just to stay airborn. The can length is a little too short to give good numbers for that app. sorta like running a .40 engine on a .46 plane...it'll do it, just not as well.

 jesusvillaa 67 points

I use at t-45 edf 65mm, esc 60 apm, 6 blade propeller, lipo 4s 30c and it is burn.

 Pepeprida 7 points

this is a ****, i put 4s batery and burn, hk have to change the info, because it say perfect for 4s an loose money!!

 rabba 17 points

I use a 7 blade in my stinger on 4 s ensure timing is set to low, also adjust throttle 80 pcnt

 -MLG- 393 points

Use 7 blade EDF so you maximise thrust, if you use less than 7 bladed EDF the flow of ail wil be too low, Because this mottor has 3800kv If you want to use 5 blade EDF than use HK 4200kv motor.

 blazer1 82 points

I use this motor on 5 blade freewing fan in my 64mm F/A-18..4s 40c 2200mah lipo..the model is unlimited and fast. about 850 grams.

 Superelectric 279 points

it will run ok on both. better on 4S. becarefull. if you running hot. in short time the stator get loose and ended breaking motor

 Pepeprida 7 points

never in 4s, i burn 2 in a second, only 3s, 11,1v

 Superelectric 279 points

estan usando mucho jugo de bateria para mover 7palas..yo tengo el mismo motor el EDF PRODUCT ID: HKEDF64..es la misma marca de tu motor y le va perfecto pero solo conseguiras de medio a un minuto mas..o compras una bateria zippy compacta PRODUCT ID: ZC.2700.4S.25..pesa casi lo mismo y mide hasta menos..son las nuevas..ojala te sirva

 Rednut 59 points

depending on the fan housing some are different i used one supplyed with plane,the seven blade fan housing doesnt work. i used one of these motors for replacment and found i had grind away the inner housing where the motor housing slots in and bolts up but dont grind away tooo much because you still want the motor housing to sit level and centre just anoth to sit flush in the fan housing with some plate groves still left job done works sweet

 Vito 5 points

if it is a 64 mm edf will not have problems is superb. I use it on a t-45 edf with 7 blades. no problem.

 ATX10 30 points

Mar11 this motor will fit without any modification. I have that same f-117 kit,I fitted with this motor and a 50 amp ESC.

 GDV68 20 points

yes it will work? but you must check mounting holes - Mounting Hole Bolt Circle: 18mm you can make new holes

 marzvt 6 points

Nope totally doesnt. I bought 2 of these for the f-14 kit and They dont even come close to fitting. The EDF units that some with the F-14 are really designed for inrunner motors. I didnt see any information about that when I bought everything so I hope this helps I ordered some motors from Don's RC that had some extentions to work. I also ordered HXT 2445 (370L) 3790kv Brushless Inrunner which totally work. I just got impatient waiting for them to come in.

 international 8 points

yes and this motor work with EDF Ducted Fan Unit 7 Blade 3inch very good and i tested torque it's about 1kg with edf 3inch :) *)

 Jose 23 points

Well, I might be wrong, but this is my 2cent: - Electrical power doesn't mean mechanical power. So, when they say 520 watts, I guess that's just the maximum intake ELECTRICAL power that it can consume, and not necessarily the true power that comes out of it in means of thrust. - Also, the drawn electrical power depends on the load applied from whatever you plug in into the axle. What kind of fan are you using? I use this motor into a VASA EDF 65mm on 4S A123, and it never got over 350Watts.

 GDV68 20 points

You should use 4s pack instead3s. The consumed power depends on current(A) and volts(V). 3s pack is 11.1V, 4s pack - 14.8V , so with 4s you get more power.

 flatspin 265 points

The current drawn by a motor depends on the mechanical load that it is driving. A motor that free runs draws very little current! If your motor draws less power from the battery than the stated power it is because your fan does not require any more power. It might have a smaller pitch fan or it might only have four blades etc. When a manufacturer quotes the power, it is either the maximum power allowed, or it is the power that the motor drew from the battery on their fan.

 marzvt 6 points

Be careful with 4s. I blew one of these up of the first flight with a 4s 50amp setup. 3s 40amp worked great with it though.

 Andres 15 points

Yes, but I recommend you buy this www.link

 Ruslan 1 points

Perhaps there was a connection between the turns of the winding. It's not scary. You just need to rewind the motor and everything. I'm rewinding. Time took about 2 hours.

 reini1755 27 points

i have the same problem and i think the sparks were produset by the scrathing magnets. i think this motor is very ***r quality. if you are looking for a 64mm fan try motorturbine 640 PRODUCT ID: D64102 this one works very well and it is dynamicly balanced

 Ingles 12 points

Check the magnets in the motor

 spanky1 12 points

I had the same sparking problem, i changed the timing from low to high and this fixed the problem.

 DK-Flyer 61 points

Amps and voltage drop would also be nice to know actually...

 Ruslan 1 points

I would not advise to neglect the factory recommendations. Since the use of 3 cans instead of 4, entails not only the loss of power, but also increase the amperage and load control, lower the flight speed and shorter time of flight.

 reini1755 27 points

i would not recomand this engine. if you like a 64mm edf take motorturbine 640, it works fine and is also well balanced

 Sawdust 1632 points

Not moved into boats yet myself but these motors are designed to work in an environment with a very high airflow and I'm pretty sure they'd overheat and demagnetize the magnets if not make that magic smoke. If you real want to use outrunners in your boat I'd be looking at some of the helli motors. Most if not all of them have some sort of turbine or impellor arangement built into them to create their own cooling airflow.

 Bloodywolf 3 points

All the motors i look at are to heavy an will flip my boat if i use the four i need for it so do you know a small motor i can use

 Sawdust 1632 points

If you click on brushless motors in the menue up further on the left of the page it opens up a list of sub categories and you'll see helli motors have their own group. Not knowing your power or rpm needs and weight limits makes it hard to recomend a particular one as best but an example would be Turnigy Typhoon 450H 2215H Heli Motor 3550kv (450 class)
This is close to the revs of the one you're looking at with probably similar power that will cool itself in a low airflow situation and is 34grams lighter.

 Bloodywolf 3 points

Thank you for the help sawdust :) Your a great person

 nicolas 7 points

pour ce genre de moteur il vaut mieux tester l'amprage en charge si cest un aroglisseur utilisation de la turbine verifier l'amperage et prener une batterie costaud

 Bloodywolf 3 points

No hable español Arrepentido

 abletowinginc 209 points

yes i have it handles it no problem on 3 cells

 MODLAR 331 points

For slow flying will be 3s ok. Better is 4 s !

 nicolas 7 points

je recois le mien la semaine prochaine je pense qu il peut fonctionn en 3s , l'amprage sera minime ainsi que le nombre de tour mais si on le prend pour une sur propulsion il pourra remplir ses fonction avec une 3s qui reviendrai a une configuration normal d'un jet

 CrashinDutchman 284 points

Try to change the timing of your esc

 GDV007 43 points

Check if all three cables make contact correctly. You can simply test them by putting them on a AA or AAA battery for a second.

 pierrehu 37 points

Maybe set ESC timer to high

 wippo76 108 points

tried all settings on the esc the best settings where high timing but still not good
tried another esc no its running smooth
but this one is only 40A and thats not enough
which one do you all recommend?
thanks for all the answers

 JelleB 478 points

change you timing setting to something a little less advanced.

 Harttvboy04 27 points

I think you need to check the PWM settings on the ESC and then also the timing settings. If the ESC's being used are not able to adjust these settings then that can be your issue. I hope it works out! Chris

 the1builder 29 points

Try reprograming your ESC. Set the timing on high. I had the same issue with a couple of big outrunners. Worked for me. Good luck.

 Phetalasy 17 points

You need to re-program your ESC to disable soft start.

 nicolas 7 points

ton controleur c'est suremen mis en securité , quel alimentation a tu utiliser, combien de C merci

 wippo76 108 points

als we gewoon engels blijven praten snappen we het allemaal ok

 GDV007 43 points

Of Nederlands dus :P Werkt de motor wél met een andere regelaar?

 wippo76 108 points

iam using this at my arttech F18 and it flys over 120KM/u it makes wonderfull sound with 64MM edf
only thing you have to use it with 4S
great motor and nice quality
tip: use good ESC because of high RPM and arround 500 watts

 Sfakias 146 points

Output Power: 520w also: Max Current (A) 35 Max Voltage (V) 15 Kv- 3800 Thrust: 1100g(38.8oz.) Recommended model weight: 600-800g Recommended model fans: 64mm Fans All of the above are listed on this item's page, and they should be more than enough to give you the answer to your question.

 Nigha 45 points

Stand by man... Mines coming... Im shoe-horning it into the Blue Angels F35 jet HK sells which BTW is AWESOME... Though up the ESC to 45Aw/BEC and run a 4S Li-Po. Only reason Im getting this baby as it ticks the boxes as far as stats go and IF HK are on their money then 1.1kg of thrust will not hurt one bit !!

 jostafew 37 points

Looks like they updated the specs (if it weren't there before). 520w at 14.8v (4S).

 nicolas 7 points

il a une poussee de 1100g avec une 4s

 davidoff 260 points

Holes are M2,5mm and 16mm between.

Only 3,5mm gold connectors in box, nothing else.

 Charlesd 746 points

Hey the Diameter is 18mm and 20mm on the other axis. This Motor would fit perfectly in the GWS EDF unit perfectly.(64mm setup)

 bongofly 93 points

hey charlesd you don't want to put this motor in a gws fan unit. The gws fan blades are soft and flimsy. It will just use mass power and give no thrust belive me I have done this. I like gws stuff but keep it small and light, like the gws stock brushless 2030 3900kv that gws sales with the 64mm fan unit. anythig too big will just suck Amps, weigh it down and will not fly well. Good Winds to all.

 mirceacul 169 points

You should try a run on the ground with smoke so that you can see the air flow and compare with a normal one...
I guess it's better for the airflow. Due to the Coanda effect which says that at high speeds the fluids including air tend to stick to the surface in proximity, there should be a good, clean, center focused airflow going out with this kind of motors.
