Turnigy 2815 EDF Outrunner 4800kv for 55/64mm

 EffinA 1509 points

45A is what you need for the motor, and your 2", 7 blade should work fine. The battery depends on your plane, but a 3s LiPo will do it, with at least a 50c burst discharge and 35c constant.

 Cody f86saber 921 points

Agreed. I use the 2815 4800kv motor in the 10 blade Dr Mad Thrust 50mm EDF, and it pulls over 33A on an old 50% storage charged 1250mAh 11.1V pack. I also have the Hoaye 51mm 7 blade fan but I haven't put a motor in it yet. I suspect that these are not very far apart in the power department. Use the lightest ESC you can get to offset this motor's weight. I used a Turnigy Trust 45A, which is a bit too heavy, and due to the tight space, the main power-in wires run along side my receiver and I had to wrap the receiver in aluminum foil to block the interference when the motor starts. I've never had interference before this speed controller. I have used Mystery ESCs with good results. If you ever find that your motor startup or throttle advancement results in momentary shuddering, adjust your timing and switching frequency settings and try it a few times. If did it again I would go with a Castle Creations ESC, and while they are expensive, they weight very little and are efficient enough that they often do not need heatsinks. I'm going to see if I can upload a pic of the motor in the 10 blade fan. Hope this helps.

42 Amps steady on a fresh 3S 1300mAh 45-90C pack today with the 10-blade 50mm EDF.

i think its not ok for 70mm. SK3 Fandrive - 3516-3300kv is better.

 EffinA 1509 points

No problem! I am using it on a 5 blade, 64mm EDF, and I think it should do the trick.

 EffinA 1509 points

Nope, you need a 40A (minimum) ESC for this one. I would recommend 45A, for the headroom. 700g of thrust is no problem for this motor with a 65mm 5 blade fan, and a 3s 1850 should push it 5 minutes on a good jet plane.

 Cody f86saber 921 points

This motor paired with the EDO five blade fan produces 700g thrust at full throttle, drawing 34.5 amps for a total of 420W.

 Arxangel 971 points

You're welcome. :)

 Arxangel 971 points

I haven't really tested it that extensively yet. I have another motor in my 64mm T-45 and this one I got so I can test it, rewind it with a higher quality and purity, Bulgarian made, copper wire and compare the results. If you put too much strain on it with a higher blade count impeller, you could end up with even less thrust at 40 or more amp draw. Best case scenario is you have a well make EDF thrust stand for 64mm EDFs, and you have 64mm impellers ranging from a 3 blade to a 10 blade, and to test this motor with all of them.

 flatspin 264 points

Den Yusuf, This is a high Kv motor which works well with a 5 blade or 6 blade fan on a 3S LiPo, where it draws close to its maximum current. An 8 blade 64mm fan will draw too much current from this motor when you use a good 3S LiPo and its life will probably be reduced

 Arxangel 971 points

This combo will be good for the motor, the ESC and the battery, they will survive for a long time. However, as for the 800 gram model, I wouldn't count on this motor to do wonders with a plane of that weight. You will have to give a strong throw to take off, and it will NOT have vertical.

 _Yuriy_ 13 points

Your setup is reasonable, combine it with ID: HKEDF64 and I'd suggest to take not so heavy battery I fly the same setup on my jetiger with 1300mah battery and total weight 600g. It climbs vertical easily! While with 1800mah battery it cannot. This setup with discussed motor gives 600g thrust pulling 39A. This motor is great at this edge! But if you will try to get more of it you're definitely are going to kill this device.

 Arxangel 971 points

You can use it with any li-po up to 3S, although using with less than 3S would give very weak thrust. Also, since the motor draws 40 amps, make sure your ESC is rated at least at 40 amps constant current to avoid burning it mid-flight.

 XRMF1 62 points

Ah I read a bit below and saw the answer, *FPV pro, comment and I will credit you lol

 Arxangel 971 points

I have ordered the 8 blade impeller, and will test it on this motor, so I will be able to tell you what the results are once I get the impeller. :)

 XRMF1 62 points

Thanks! I'm also hoping to use this on the T-45 so let me know how it flys with it :)

 Arxangel 971 points

If test are good, I will be flying it on a T-45 as well. :)

This motor will work well on 64mm 3s and 4s, although using 4s will limit the lifespan. also, you might want to look into getting a 2200mAh battery, as it will provide a much longer flight for not much more money

 FPV pro 19 points

The 35-70c rating will limit the lifespan of the ESC/motor, as the coils/capacitors will be burnt out. Using 35-70c will more than half the life of each.

 Arxangel 971 points

What is the logic behind the battery's high C rating, and the ESC and motor having reduced life?!?! The two things are not related, the high C rating on the battery shows that it could deliver more amps IF the motor can draw them!!! A high C rating is a good thing in every situation, because it INCREASES the life of your battery, especially in high load applications. What could limit the life of your ESC/motor is if the battery is 4S, i.e. higher voltage than the ESC and/or motor can take. This can fry both of them if they are not meant to be ran on a 4S, otherwise if the above battery is a 3S you can absolutely use it.

 Cody f86saber 921 points

You certainly can, and that sounds like a good component compliment. These type of motors are typically excellent at staying cool in 50-64mm EDFs because the magnet and coil assembly are in the direct path of the airflow. If this was used in a gearbox, I would try to ensure it had plenty of ventilation. I hope this helps, best wishes.

 FPV pro 19 points

nano tech lipo battery 2200mAh 35-70c - right mAh rating but max 25-30c...... 30a esc - need 40-50a ESC (you can use 30 amp, but it will not last for very long...... EDF Ducted Fan Unit 8 Blade 2.5inch 64mm - yes, works great in my plane...... plane weight 500gr - yes, my plane manages with 655gr take off weigh on the same motor.

 Arxangel 971 points

OMG, first, Den!!! state the battery pack cell count, the C rating is not relevant. This battery is fine for this motor as long as its not more than 3S, however you might want to change the ESC because the motor draws 40amps max, while your ESC can handle 30 amps, but this has nothing to do with the C rating of the battery. FPV pro, stop misleading people!!!

 FPV pro 19 points

This motor will work in any 64mm fan system provided the weight is less the 850 ish grams (I am not familiar with the Dynam F-16, but this motor works great on all my other edf planes)

 KaosKane 1442 points

Imo a 7 blade EDF is far to torquey for this motor with a 4 blade i draws 40A a 7 blade fan would be roughtly 2 and a half times the amps so over 80A which will fuse this motor instantly..
Ps even with my 4cell lipo i keep the max amps to 40 bu restricting throttle % to 80% HTH

 mikec@aloha.net 228 points

it was recommended to use this motor with a 7 blade fan. i have and i get tremendous thrust at not even half throttle. i never go full throttle though since none is needed. and i use Rhino 40c 3s battery. battery is warm and does not puff. so you can use higher blade but not consistently at full throttle. the fan has a nice sound too with 7 blades.

 Cirodi 2 points

Hi Mikec, you bet. In the meantime I got a powermeter* with 3s * full throttle the A is below 35, the EDF has a nice thrust and the motor doesn't get hot. The important thing is to remove the EDF motor cover and let the motor rotor to get the air flow. Best.

 __bare 721 points

Buy and Use the 3500 KV version motor with the Haoye 7 blade EDF for 4S. Why fit a motor that you cannot use full rpm on?? More than pointless.

 Daniel 66 points

Running THIS Motor (4800kv) an OK-Model 7 Blade 55mm fan on 3S (nano tech 45-90C). Measured several time on a RCLAnder 60A ESC and on a HK Plush 40A ESC it always draws about 30 - 31 Amps (measured with HK G.T.Power). So nothing of 80 or 100 Amps...

 mikec@aloha.net 228 points

i like keeping the amps low

 Leandro 22 points

No maximo 3s.

 DOUX 4 points

Yes you can use it with 4S but with a 55 mm fan only, be carefull with amps (better to use a 40A ESC and high discharge battery packs). I use this motor in the 50mm 6 blades from HK and my mini F18 is a rocket (but I only have 2min30s flight time). Very good motor for that price, I bought 3 units!

 KaosKane 1442 points

i use this with a 4 cell 2200 35c lipo and a 64mm edf i limot my throttle travel to 80% to keep the amp draw at the max HTH
Ps i have this setup x2 in my A-10 kit Very fast

 KaosKane 1442 points

if u meen this one. T-45RTF T-45 Goshawk R/C 64mm EDF Jet EPO Plug-n-Fly 1 Reserved it haa this motor. Motor: B3830 Brushless Outrunner 4300kv
so this motor at 28mm is smaller than the 38mm stock..
you could use it but u would be better off choosing a 38mm motor to suit

 herropreeze 27 points

Ok thanks - sadly I have already bought this motor as i couldnt find the same size - but confirm i can still use it, in terms of performance?

 KaosKane 1442 points

yes try an find a collar to fit between the motor and the edf shroud or some washers if u can't find anyhting else mounting it dead centre will be the hardest thing and dont rely on two bolts for edf to shroud mount drill more HTH

 herropreeze 27 points

well its academic now cos I have destroyed my edf - sucked a stone in while taxi ing and shredded the fan!

I ahev ordered two replacements one 5 blade and one six blade (both 64mm from HK) I hope they work!

 herropreeze 27 points

This motor fits perfectly into the stock shroud, i have mounted a five blade fan on it and it is sounding good. I have a six blade fan but am wondering if it will cope with six blades?

 KaosKane 1442 points

use a 3.00mm drill bit ot get 3mm piano wire HTH
ps both these items r cheaper than the postage cost of a tailor made shaft

 steven5 16 points

load current means with an edf how much is the maximum Amp that it can be efficient. if you want this motor then you should buy a 40A ESC (with ubec) and a 3S battery that can give more than 40-45A (= Ah * C rating) that means your battery might be any of the following batteries: 4Ah*10C-or-15C, 3Ah*15C, 2.65Ah*20C, 2Ah*25C, 1.8Ah*30C, 1.3Ah*35C.

 steven5 16 points

correction the esc without ubec 40A if you have your own ubec. With ubec 45A Esc.

Not that powerful on 3S? How many watts? Any idea of thrust in grams?

 azeez 6 points

cannot specify, speed is ok but not that high, I dont think my 3s2200 is heavy for it, could try 1800 MA. but worried of using 4s, specs does not say its supported

 KaosKane 1442 points

Most likley Ur lipo can not supply the amps needed. upgrade to 65c or above
example 3s2200 30c =66A PEAK. Amps drop off and lipos heats up in seconds if PEAK load is maintained

 Discus2a 80 points

Well that's quite normal as there is no airflow around the motor. When you'd put it in your EDF it will cool down enough. Also it might not be a really good idea to run it at full power with no load. It could be having a too high RPM, with excessive wear at the bearings? LOL * the f*cking Ethan guy btw!

 Ethan 102 points

its normal i also have the same motor for my yak 55 i just let it cool down after something like 5 minutes..
hope i helped you:D

 KaosKane 1442 points

ur batt is prob 20 or 25c not enough amps geta 1300-2200** 3c 35c lipo and it will even go faster as well i use a 2200 4cell 35plus c batt on my upgraded jettiger i have crashed 20 times as this was my first edf i call it the splodge as this describes it shape lol *}

 flatspin 264 points

I use the same fan and motor configuration on the HK Mig 15 (64mm fan) and it is very good. The motor is very reliable and is still going well after a hundred flights. I use the Turnigy plush 60A speed controller (as the motor draws in excess of 40 amps) and this is why your 3S 800 LiPo is getting hot. You need a 3S 2200, 30C or 40C LiPo. I am pretty sure that the Jetiger was designed to take 3S 2200. Do not use a 4S 2200, the motor is too hot for 4S.

 Cirodi 2 points

Hi, I'm interested in using it with a EDF Ducted Fan Unit 7Blades 2.5inch 64mm (item OR003-00108-7B) driven by 3s (11,1V). Any idea about the compatibility of this configuration? Current load? Thrust? really appreciated. Thanks. S

 KaosKane 1442 points

hard to say fer sure try setting the timing on ur esc to and bench test first *} ls buy a wattmeter.. hk have them for like 20 bucks so if it saves u 1 esc ur even HTH:} if all ok go to 6 blade efd or sand the impellers to increase the gap between impellers and edf housing wall :}

 flatspin 264 points

Does your motor speed controller combo still work? If not, it's probably your speed controller! Speed controllers generally work harder at mid throttle than at high throttle.

 Sugna 189 points

The ESC is still working fine. So I don't think that's the source.

 Greenfuelboy 163 points

This motor is supposed to be ran on low timing. Maybe the ESC is set wrong and creating heat.

 Greenfuelboy 163 points

I have used this motor with a 55mm fan and a 64mm fan. I never checked out the 55mm it never gave me any trouble. My 55mm fan would only pull about 27 amps. It was a cheap 5 blade from a Electrifly jet. I soldered longer wires of equal lengths to my esc. I put the ESC in the air duct so it will get full air over it at all times. I have another one of these motors in my F16 with a 64mm fan. I had a fan with seven blades and it pulled too may amps on the watt meter. That does not mean that all seven blade fans are bad. Some have less pitch. After testing my motor with a different 7 blade and a six blade I am pulling 32 amps and the motor runs very good. If you put the ESC in the air duct it will never get hot. Use a watt meter you will not have any trouble. I am using a Turnigy plush 40 amp esc.

 Brain 112 points

They were prob using the 64mm 6 blade fan.

Forgot to mention planes used.eurofighter typhoon,f18,and airfeild f15.all planes have been around for two years now and still perform pretty close to my 70mm jets.hope the info helps

 flatspin 264 points

This is a superb motor on a 64mm 6 blade fan. However, it will draw about 50A on a 3S LiPo
