hey all ive been reading ya comments for weeks i have got a few planes nitro and electric i bought this motor for my f-18 jet from hobby king i have had 4200kv and 5000kv wit 30 amp hk and 7 blade fan speedy blows the motor in first 30 secs now i have got a turnigy trust 45 amp speedy 5 blade turnigy blades and running it on 1800 4s is this good setup or am i wrong cheers guys
I would take this motor into my Pylonracer with 710mm wingspan and 600gr flying weight.
I want to handle this one with a 4,75x4,75 prop and a 40 Amp Esc.
Does somebody know that the motor dont want burn the 40 amp Esc?
Sorry for bad English, im from Germany *)
Can someone tell me how to fit this motor in a 70 mm changesun fan I can't get the motor wires thru the mount part to screw in the motor . Why do some motors have the wires come out the bottom and some the top.with the top the wires will run thru the back of fan
jhova1717, The wires always come out of the stator part of outrunner motors like these. The bell side is the one that spins. With these type motors, you must consider the size (2836) 28mm wide x 36mm long. If 28mm is too wide for your housing and/or has no place for the wires to exit, you may have to consider an inrunner motor where the entire motor is stationary and the rotor inside spins. This way the wires (as far as I know) are always are out the back. Hope this helps and Happy flying!
Thanks I figured it out the wires fit thru the holes on the mount you just have to slip one wire thru the hole you pic at a time . It's only a little bending. Someone told me you can also punch the shaft thru on these turnigy motors if you want.
Hi John, Try starting a new question to get a reply. You have inadvertantly posted your question as a reply. Although I don't think this motor will work because of cooling issues. It's impossible to mount a heatsink on an outrunner bell.
Glaydson, I would say easily. My F-22 had a 3S 1300mAh 45C, a 6x5.5 prop, and a 50A ESC and this setup did fine (with the exception of tearing control horns out of the depron). I plan on building a stronger airframe for this setup. Loads of power! Hope this helps and Happy flying!
Yes go to (headsup rc) get the 60mm shaft if nessary cut slight protruding shaft down 4mmin back of motor perfect fit.Or leave as is works fine too. YOU might have too extend key way on shaft with dremal tool for grub locking screw to line up it should be easy to acomplish if you have a dremal tool good luck.
You will burn the motor up if you exceed the stated 520w max only can acomplish more watts with more cooling and you are very limited with this motor aplication for that. I would say 470w would be a safe wattage to run this motor at. This motor does not handle heat very well and will smoke if you exceed its rateing. Good luck
Brian, are you talking about the funjet ultra? Then the 4.75 x 4.75. I have no idea about the amps but used a 75amp speedy that i purchased for another project. And WOW it will honk. I used a similar motor with less 2800kv in mine.
Great! I'm quite sure I had in excess of 100mph on a few passes. But, I'm going to build a new plane just for this motor. My old one keeps tearing control horns out of the depron. Ha ha! Just bought another one of these motors when they came back in stock. When the plane is done, I'll be sure to post some video. Take care and Happy flying!
you can definetly use the motor on the changesun 70mm 10 blade EDF. Although, with a 3s lipo it wont produce as much thrust as a 4s would or use a 5s this motor can handle up to 5s acording to the specs.
edfman, i think that the motor NTM Prop Drive 28-36 3000KV / 755W is better for this edf. i think that you can use it on 3s and on 4s becouse it is only 3000kv and can produse 755W and can handle more amperes . more than the Turnigy 2836 (650W). i think that i will buy this motor for this edf but i dont know if it fits. what is your opinion?
harstat,it will fit.I thought that motor looked very intresting also I have not used that motor though so I could not give any feedback to you on it.I have three of the edf versions and they are good motors I can't tell the differance between them and the freewing 3000kv motor I have.I think 3000kv will give very good performance for you on 4s it will run at44400rpm and the max rpm on that fan is 45000 so you will be at peak performance plus making that cool turbine like jetwhistle sound that I think your after.good luck on the motor you decide on
NTM Prop Drive 3536B Series Replacement Shaft. It will give you a 4mm shaft on both ends of the motor. Perfect for a Stryker-Q with 4.75x4.75 APC. Had to carve (jigsaw) a piece of aluminum to make a mounting plate.
Motor is still cold after a flight.
yes u can run two motors on the one plane u will need a Y splitter to join both ESC's together than plug it into your receiver u can either run both ESC ** to the same battery or run one ESC to each battery if u run duel batteries
Here is a video showing it clocking 88mph. When I put my Nanotech 45-90C in it, thats when things get real interesting!! I need to put more limits on the throws and more expo so it will smooth out a bit. Ha ha! Depron keeps breaking around the control horns.
Sorry, this video was the KD 3200kv motor with a 6x5.5 prop. I have not gotten any video of this with the Turnigy 2836 3200kv motor yet. When I took it out for testing (6x5.5 prop), it blew out the elevons in a quick turn and crashed. After repairing, I put a GWS 6x4 3blade prop the prop exploded! This broke the end of the motor shaft flush with the motor, and caused another crash.. Ha ha! I'm quite sure it was in excess of 100mph. WAY fast.
Oh, BTW, do NOT try to run the MAS 6x4x3 blade prop with this motor. That's what I should have posted above but I mistakenly said GWS. Anyway, this motor turns the MAS props into C4! It EXPLODED during flight into 3 different directions. I patched the plane back up and put the old 2840kv motor back in. Now it's back to a 60mph plane. I intend to build a Cat plane for this motor and will post video when done. Take care and Happy flying!
I would think a 6x5.5 prop with a 3200kv motor on 3s like this one would be an overload...Unless you have a good 60amp esc,some 40c batteries and a very low drag light plane...I would prop down to a 5x4 or 5x5 and monitor performance and heat...Things can catch fire or get fried pretty quick sometimes...
I had a 50A ESC, 1300mAh 3S 45-90C and the scratch built F-22 all up weight was only 10oz. It was spooky fast with this motor. The control horns kept tearing out of the depron if I pulled too hard. I plan on building another with smaller control surfaces and shorter throws. Not sure of the speed with this setup but it seemed to be 100 plus easily. Low flybys were next to impossible so I had to keep it 20 to 30ft AGL.
I was using a 6x5.5 APC prop. The points changes your status but I think after you get 100 or something like that you get a discount on just about everything. Plus when someone gives you credit for an answer, not only do you receive points but a few cents toward a purchase from Hobby King. I made most of my points and a little change by answering the same questions over and over.. Ha ha! Kinda fun to help others out and even better if they show video of their wares when they complete a project. Take care and Happy flying!
Oh, your screen name, well, I never crash! Ha. Some landings are just a little harder than others or not in a designated area. I've had many touch and goes where the second touch was in several different locations.. Ha ha!
Thax for the info...Yes i think a 6x5.5 would put a load on that motor and actually lower rpms...i bet you would have gotten better speeds with 6x4 or even a 5x4 or 5x5...i learned a lot when using various pitched props on my rc electric boats...i fried esc's and blew up batteries,but i learned a lot in the process..
Still have the motor, ESC, and plane. I did plan on using this setup again but with a 6x4 stryker prop. I've heard they do an outstanding job. So when I get around to building another propjet (too many other projects now.. ha ha), I'll try the 6x4. If that doesn't give me the results I want, I'll go back to the 6x5.5. The setup I had handled it nicely with no heat on ESC or motor. The battery only got warm but not hot. This motor is rated at 54A with 12V and the ESC is 50A with a burst to 80A. However, I am thinking of going 4S next time. Take care and Happy flying!
Okay,Its either a ****py prop or a not so good airfoil...I bet that motor on a radjet with a good apc 6x4,45amp esc and 40c 1300mah 3s would do no less then 110mph...actually more like 120 or 125mph IMO...I have my radjet doing 85 plus mph with a cheap 5.5x4 25amp esc,2200kv grayson microjet,1300 20c 3s...
Has anyone tried to turn a 6x5.5 prop with this motor? Just burned up my KD KA450H 3200kv motor. It looked cool though! traveling at just under 90mph and then a smoke trail across the sky! But sadly, that was the motor saying goodbye.
Yep! I've got a scratch built F-22 and it has an open fuselage to keep ESC and motor cool. My fault about the KD 3200kv. I ran two 2200mAh 40C 3S back to back... having too much fun. The saw white smoke as I did a high speed fly over. Looked cool but I knew something fried. LOL. I turned the nose to the air and gained altitude just gliding and brought it in to find black windings.
Motor and plane performans strongly depends on design of the prop, not only on size. I examined 5x5 HK APC-style and 4.75x4.75 (some black one from HK) on MPX funjet. 5x5 gives strong vibrations and hot battery (2600 3S, 35C) but no speed and acceleraration. Black 4.75x4.74 the same picture. Best prop which I tested was MPX 5x4 from brushed easy star combo! Maximum speed unlimited vertical performance and no vibrations and heat!
Sky guy, Need to know how many blades on your EDF to calculate the thrust. On an EDF the Static thrust will be greater than the prop stall thrust, so you must go with the lesser one. I'm purchasing this to use with a 6x4x3 blade prop. This setup full throttle should be 92oz. thrust with a pitch speed of 135mph. I'm sold on 3 blades after using them on my quads. I hope to get 100mph from my all up weight, 11oz. 24" wing span F-22.
Ron, exactly what i'm looking for, i have 3 edf unit to set with my 3 jets, all 70mm F22, 5 blades, 6 blades and 3 blades. So far the 3 blade gives the highest static thrust and a faster flyer compare to the other 2, and the 3 blade has a far more solid sound. except i dont have any scale or apparatus to measure the thrust. Thanks for your www.link
Sky, I calculated this with 2200mAh 3S 40c, a 50A ESC and this 3200kv motor. Not knowing the pitch speed of the EDFs I calculated it the same as the diameter.. 70mm. With this, for the 5 blade it yields 7oz. thrust* the 6 blade is 7.12oz. thrust* and the 3 blade 4oz. thrust. With the pitch speed equal to the diameter of the fan, the pitch speed is 93mph. With a 70mm fan, you can go all the way up to a 5000kv motor on 4S. Hope this helps!
Sky, Woops! Don't try to use a Master Air Screw (MAS) 6x4x3 with this motor!! My plane flew quite fast for about 30 seconds until I opened the throttle all the way. Then It flew only a few seconds and the prop exploded. Half went through the lower left side fuse and the other half through the right vertical stab (cookie cutter style! Ha ha!). It also broke the motor shaft flush with the face of the motor. It sounded pretty cool for a moment! All repaired and re-installed the little FC 2840kv motor for a 60mph bird. I'm getting more of these and making a FAST propjet or two.
RonRC i think u are giving false information under 200 grams of thrust using a 70mm EDF? are u kidding? please do actual testing i tested this motor in a ChangeSun 70mm EDF 4 blade 1500mah 4S i got 37.5amps 479watts on 3000mah 4S i got 43amps 616watts
on the first measurement i have about 1-1 maybe a little under 1-1 thrust to weight in a 1kg jet
As I said, without knowing the pitch speed of the blades and number of blades, I factored it in using the same pitch speed as the diameter. Props are much easier to calculate and I've used 6x5.5 with 3S battery and 50A ESC with phenomenal results.
I guess to fit this in the change sun 4 blAde you have to reverse the shaft ? I thaught since it said edf motor it would fit rite in this was my first edf fan and motor purchase.but when I tried to fit it after soldering the bullet connectors it wouldn't fit thru so I figure it has to be reversed! Can someone help ? Thanks
I bought two of these and hooked them up to two 80 amp escs, battery is a 4000 6cell lipo. Also bought two of those 10 blade 70mm edf fans you guys have been talking about. sounded great but on the first flight, had to bring it down after one flight cuz one of the motors started smoking. So now im down to trying the 6 blade and possibly buying another one of these or getting a motor with a lower kv like a 2700kv with 500 watts power. Any opinions/ other options?
I picked this motor (based on the product video) for my Electric Pylon Racer.At the same time I also ordered the "Alloy e-Prop Spinner D30xH30/3.17mm Shaft" (wasn't comfortable spinning these RMPs with the supplied PLASTIC spinner assembly). In setting up the plane, I've run into an issue (well first one was having a 25-35K spinning outrunner enclosed inside the plane). Motor mounts from inside the plane so only the shaft sticks out - no "mount", no adjustment. The shaft on the motor is too long for the collet - it bottoms out with about 3/8" left leaving a BIG gap between the spinner backplate and the nose. My question is, is it normal in ANY way to CUT the shaft down? Also, how to you keep the shaft from spinning as you tighten the collet down??
Yeah, that's how I USUALLY do it, but never worked with a "slip-fit" collet before. The collet slips on the shaft, spinner backplate, prop, prop washer then nut. Once the nut is finger-tight, turning the wrench just turns the collet and shaft, going nowhere.
I don't think it's possible to hold the motor after you put it inside the plane and you have to put it inside before installing the propeller... I know it's not an answer but my only idea is to use a different kind of spinner like a grub screw type.
Yah - that's what I thought...need to get a new one anyways. The threads on the alum. shaft that came with this spinner (from HK ) stripped almost as soon as it met any resistance - as in tightening against the collet.
i have this motor as well for my Funjet and use a collet type shaft prop adapter, what i did was file the shaft a bit so it has a flat side, so far the prop adapter never slips. Even on EDF fan with collet type also never slips.
GhiaMonster, I put a little lube on the threads and bevel of the collet adapter. I know it's tough to tighten when you can't hold the motor. This way, when you tighten while holding the prop, and feel it start to slip, back off a little and give it a quick quarter turn. It should start to tighten then. Then you can tighten it the rest of the way up. Just make sure you don't get any lube on the shaft or inside the collet.
foysekis the power is only a little different. On will spin faster per volt put to it (ie: 3700). So it does depend what it is spining. Everything being equal and assume you do not over load or over heat the motor the 3700kv will give more power. I hope this helps
Can someone please tell me why i keep blowing up these motors in my funjet. Funning 85A ESC, 4C 1800 mah batt, 5.5 x 5.5 prob. Last one make it to full throttle for 3 seconds. Any help would be appreciated.
en 4s 2650 40c le moteur résiste avec une 4.75*4.75, par contre avec une 5*5 le moteur explose, la conso mesurée avec la 5*5 est de 85a et 1150w a ne pas refaire par contre avec la 4.75*4.75 la conso est de 65a et 900 w a ne pas dépasser !!!!!
Could this motor be fitted to the skyfun jets stock motor mount as a direct fit? If not could someone please give me a link to a good mount compatible with this motor and the skyfun jet. Thanks guys :-)
all engines in this category are arranged that way, there are some commercial adapters, dde difficult to get, so I recommend investing is simple you just have to put a collars in the back a prisoner. I've done in my Canadair CL-415 and work perfectly.
Using 4.75 x 4.75 prop will gave you static peak current around 88Amps, 1080Watts with 740grams of static thrust. You should not run the motor at fullspeed no more than 10sec on the ground without proper ventilation this will overload the motor. Though this motor was design for 70mm EDF 3-5 blades, using 2 blade will surely overheat the motor. Hope this helps.
My motor 2836-3200 has jut arrived. Checked kv and other specification. Mine is a 3200kv-motor !! May be different from Peter's. Good Motor measurement data is on my web www.link S400 4.1x4.1 10.13V 22.51A 28350rpm APC S400 4.75x4.75 10.07V 27.43A 23940rpm APC S400 5x5 10.50V 34.61A 24570rpm (High volt) APC E 6x5.5 10.68V 66.47A 21900rpm ALP2200HP3S(22-40C LiPo)

Tested this motor on a 70mm airpower fan on 3700mah 4s1p Holding the fan(not recommnded) when the wattsmeter hit 840 watts i killed the throttle. Seems a lot hotter than 3200kv,checked to see if perhaps i wasnt sent the 3700kv by mistake but sealed box said 3200 so is correct motor, if they genuine figures and the motor can handle 60plusamps then this motor is serious value for money. Will test again in a model where its safer and give more detailed results, but have bought 15 now for stock and if they as good as i think they will be the next best thing edf motor wise, testing will tell

Ubelievable speed in the F-27 Stryker. Turnigy Plush 40A, Rhino 1750 4S 25C, APC 4,75 x 4,75 gave static WattsUp peaks at 88 A, 1080 W and 740 grams static thrust (better in flight). Short periods <10 sek at full speed have worked without overloading the motor, ESC or battery for many flights now. Even at 1/2 throttle it is quite fast.

I paired this up with my Wemo 70mm DF, 4s Zippy 2100 and I was pulling around 750watts(Initial Burst) and settled around 690ish :-O
