HK2627 EDF Outrunner 4300kv for 64mm

 Wojciech 11 points

Yes u can. It will work like a charm. Before first flight u can take load measurements. I use it with 7 blade fan and everything is ok.

 Wojciech 11 points

Hi, I don't and I think it's not a good idea. It is up to 11.1V so 3s.

 Wojciech 11 points

Yes, you should use 40A (or more) ESC. For example: Hobbyking SS Series 40-50A ESC

 Gary 2988 points

It sounds like the ESC is in programme mode,try reversing the throttle function on the transmitter and try again,also make sure the throttle trim is all the way down to low throttle.If you have travel adjust on your transmitter try increasing the throw in the closed throttle position.

 jetz03 29 points

how do i reverse the throttle function? i have this transmitter : HobbyKing HK6S 2.4Ghz FHSS 6Ch Tx & Rx (Mode 2)

 Gary 2988 points

On the front of the transmitter you have a row of switches,2nd in from the right is one maked "THR",slide this switch to the opposite of where it is now and try again,make sure everything is switched off when you do this.

11.1v 2200mAh is what i use, it all depends on weight of your plane

 jetz03 29 points

um...lets just say my plane is about 550-600 grams of weight, then i use 2 of these 'edf motors' would that be enough? and also with 2 of these motors whats the total thrust?

 Jase73 282 points

Google search for fancalc use vesa 65 for the fan type that seems to be an average for a 5 blade fan. then go for a turnigy motor, then change it back to custom and type 4300 in the kv section... play with the numbers so see what thrust you get amps etc...

 Jase73 282 points

Yes, but only if they are spinning the same direction. You would also need a big esc as these are rated 36amp 70amp red brick should do the trick

 jetz03 29 points

2 of that esc? for each motor?

 Jase73 282 points

What I mean is, if they are going to be turning the same direction, you can run both motors off 1 esc, pref at least 70amp probably higher, depending on how you prop them... if you need them to run in different directions, ie to counteract tourque roll, then you will need 2 esc's upwards of 50amp each.

 jetz03 29 points

what would be the consequences if the ducted fans spin in the same direction?

 Jase73 282 points

it rolls in the opposite direction.

 Jase73 282 points

3s I use the 2815 4800kv and it's $12.79 www.link a 5 blade fan, www.link with a 70amp hk red brick to run it. Servo's, I have only used 9g servo's I've started useing the metal gear servo's, peace of mind that they won't strip gears if the worst happens in flight...

 jetz03 29 points

lets just say im trying to build a f-22 raptor about 400- 500 grams and i use two of these motors would that be enough?

 Jase73 282 points

the battery is 180-200g 2 of these motors are another 160g, so that leaves you 260g for your hardware and airframe...

 Jase73 282 points

Have a look at this for hints on a f-22 build... http :// www . rcpowers . com / community / threads / f-22-easybuild-v2.6006/ take out the spaces for the link...

 Dongskie 228 points

Yes you can, but flight time will be sacrificed in half as compared to a single EDF set-up.

 Dongskie 228 points

Funny how did that attachment get in there?

 jetz03 29 points

not quite, you need a 3-cell battery but higher 'mah'

 Jase73 282 points

You would need a 40c battery as I'm puffing my 20c a bit with one of these... make sure you turn brake off on your esc or you will kill it...

 yongteck78 11 points

yes u can if it is using 64mm fan.

 flybug111 24 points

The ring before the bell is a bit too big and the mount on the fan is a bit too deep. You would have to grind some of both off then it would slip right in. I hope this helps.

 Nin3rsAllDay 5 points

I've ordered this motor and in a 64mm jet running on a 3S pack it seemed to do the same as the stock motor I would think if you are running on a 4S pack it should work well and provide plenty of thrust. Do you happen to know the kv rating of the motor that came with the F-5e?

 KaosKane 1429 points

yes the number of blades is inportant for motor loading more blades = more load at same kv (rpm)i used P2627l and the fan in the recomended section for my stinger with HK 35A esc and 2200 4cell 30 c bat went very fast. using this motor less amps and heat so will be slightly slower but have less heat so it lasts longer.. with throttle controll u will be fine with this motor and the related fan. ps this will still be 2 fast for a beginner :}

 Napstr 686 points

I think you will have to be more specific as there are other factors indicating the suitability of this motor to any fan. Factors like the pitch and chord of the blades affects current draw as does the number of blades. I have only tried it in the gas 6 blade 64mm fans and they are great so for 7 blades you will probably need less pitch and/or less combined chord to work.

www.link this 7 blade edf,.. thx

 Jase73 282 points

on 3s it should be fine, 37000 rpm ish according to fancalc but Get a 60 amp esc to be on the safe side... *-)

 Napstr 686 points

Hi it isn't mentioned that it can run 4s in the specs but I know some who have done so with no problems with over a years flying- the secret appears to be keeping the blade count down on 4s.

 eckman69 20 points

Yes, it works very well on 4S. I used a 5-blade EDF, not sure if this will work on 4S on a 6-blade EDF.

 theSelf 45 points

this seems to be the motor used in the stock PNP version of the 64mm Stinger sport jet- some people said they tried with 4S but only lasted so long- are saying use a 4 or 5 blades EDF unit for this to be safe with 4S? thank you for your reply

 KaosKane 1429 points

it is not the same as the stock motor in my s64

 Adam. 2 points

I'm looking to run this on 3s w/ the HK 6 and or 7 blade. Anyone have a thrust calculator?

Thanks

 Jase73 282 points

www .s4a .ch /eflight /fancalc_e.htm works quite well and tells you what is just a bonkers combination...

 Adam. 2 points

I am a relative noob. I can't figure out what to use for FSA, should it be 80%?

 Jase73 282 points

simple, keep it at 100%, anything else it drops off. just use this thing so you can match motor to blade count and esc.

 Adam. 2 points

Am I missing something? How do I customize the # of blades? Looks like the only 64/65 mm is the VESA and that is a 6 blade fan.

 Jase73 282 points

just for giggles, use one of the 69mm fan profiles... it's a rough guide... it's really just to help you size up your motor and esc to a fan, tell you if you need more cells, then a bigger esc, then a lower kv motor etc...

 Napstr 686 points

The motor can be used as a pusher but the mounting will be the same so there is no cavity for the screws as it is not required

 remauled 26 points

Thanks, I meant I need the motor to have screw mountings both in front(to EDF housing) and at the back (to fan blade) so that it can operate as a pusher. Is there mounting points at the back of the motor? The pic doesn't show.

 Napstr 686 points

Hi I have just checked and the motor can be reverse mounted as you described - the back of the can has 3 tapped holes equispaced around the can and it appears to be 2.5mm thread so it is possible to mount the fan direct to the can.

 eckman69 20 points

It works great as a pusher. Some of the GWS motor mounts (the black ones) that act as stick adapter are excellent for this motor. Use a 5.5x5 prop

 Jase73 282 points

 Napstr 686 points

The answer to your question is not straightforward as it depends on many factors - the number of blades and the chord of the blades - also the pitch of the blades has an effect - the only true way to answer your question would be to use a wattmeter to check the amount of current draw in your situation and some form of scales to measure the thrust

 Skanda 2 points

Thank you Napstr. But can we atleast like gauge what might be the change. As in out of experience can someone say like yes around 10A excess current will flow. something like that. The 70mm EDF which i have bought is www.link Thank you all

 Vito 5 points

hello Skanda, this engine is not for a 70mm FES because EDF mounting holes do not match those of the motor and the power is not enough. buy a motor for 70mm not to make changes unnecessary.

 Jase73 282 points

it's going to be too much I'm afraid. its more a 5 blade, 64mm edf motor, possibly going to 4S for bursts. but 70mm will be too much... have a play with this... http :// www . s4a . ch / eflight / fancalc_e . htm you will find it very usefull in picking a motor for fan's before you spend any more moeny... *-)

 Napstr 686 points

Yeah this would give the F-117 a bit more go - I would try smoothing all the fan ducting first to ensure the airflow isn't disrupted - but for more power this is a good bet.

 Mar11 1990 points

yeah but i mean will this motor fit in place of the stock one ? in same size duct ?

 Napstr 686 points

Yep it will fit inside the same duct as it is much the same size (length and width) as the stock motor.

 eckman69 20 points

This is a great little motor. If the fan has 5 blades and takes 3mm shaft adapters, then it should be perfect. I would recommend getting fan unit HKEDF64 to go with this motor, it delivers great trust with modest power consumption. The motor fits perfectly in that fan, screws align well and the adapter fits snug. It's less than 4$.

 david alfasi 2 points

Do you I can use it with 6s. ?? I have turnigy 60 amp esc

 Mar11 1990 points

No dont u will burn it !!

 mksubaru 56 points

i am sorry i mean 4.1x4.1

 Kevin 8 points

How about try a 4.5 by 4.5 Safe way is to go with the 4.1x4.1 and use a little bigger speed control to be safe.

 coptor 35 points

4.1 x 4.1 on a 3000kv will draw 20 amps. On a 4300kv that could easily shoot up. Get a watt meter to be sure.

 e_lm_70 421 points

Yes, but you should not exceed the 36amp :) Honestly you put this little motor on the edge on 4S, maybe with a 3 blade fun is possible. I'm going to use it on 3S set up, it will have more then enough power. For 4S, you need less KV, and a bigger size motor.

 e_lm_70 421 points

It come naked, so you need an adaptor. Some EDF unit (without motor) come with adaptor.

 AeroEscolaFly 86 points

This outrunner motor comes without adaptor. If you buy the 64mm EDF system it will come with an adaptor.

 H-KING_SCOTT 5161 points

40 to 50A would be best.

 Uberfest 31 points

ok, 50A the best!!!!

 e_lm_70 421 points

It does use around 30amps on 3S on my 64mm EDF ... For 3S 40A ESC is very safe ... for 4S, you need 50A or more

 mksubaru 56 points

how many blades on your EDF ? will this motor handle the 7 blade 64mm sold here in HK ?

 Francisco 41 points

En lo personal, ningun EDF 64mm es rapido. Pero sin duda es la mejor opcion este motor, ya que manejandolo con un ESC de 40A no tendras problema, pero si necesitaras una lipo de 2200 mAh www.link the personnel, no EDF 64mm is fast. But without a doubt it is the best motor east option, since handling it with a ESC of 40A there is no problem, but you would need one lipo 2200 mAh 3s.

sometimes a small metal shaving inside or a sticky bearing a loose or crooked magnet even a little blob of epoxy could cause it

 Whiskers 108 points

Check the end-play in the tight motor. Slacken the grub-screws and see if you can give it a small amount of end-float

 Marcio 7 points

dear friend it is important that you have the correct amperage ditribuido times with the same engine working corretes deferens and is always impotant have a multimeter, careful you can burn your engine ...

 KaosKane 1429 points

many people say to put a vsmall bead of cf around the base of magnets to hold better then just run em until they snoke :}

 k.smith459 52 points

try rewindind it

 Prego 52 points

NO!!! You should use a 60A at least... because the 40A is indicate only fo 3S

 MrEpoxy 42 points

Even with 60A ESC, will this motor hold up on 4S when the Amps goes over the 36A max current rating as stated? This is more of a question than comment. Appreciate someone knowledgeable who can answer. Thanks.

 2stroke 83 points

reply to mr epoxy, i should think not, it WILL burnout, it may go to 40A burst but its a guess, simple just get a bigger motor, with higher amp rating.

 sorenlaf 92 points

In general, motors are limitted by current, not voltage. For a given rotor (or prop), more voltage means more rpm and more current.

What this means is that without knowing the fan you're using, and without knowing how much current that fan requires on a 3 cell, we really can't say if a 4 cell would be okay.

ESC's do have a voltage limit, because the mosfets in them have a voltage limit. Motors (within reason) only have a current limit. The insulation on the wire in the motor will eventually fail from excess voltage, but probably not until a couple hundred volts.

All I can suggest is that you try this motor out in your fan and see how much current it draws on a 3 cell. The motor has a 36amp burst rating. I'd try to keep it around 25-30amps continuous (depending on how brave I felt, and how hot it gets), and let that dictate the battery voltage.

I'm buying one to use in the HK F14 edf jet. When I know how much current it draws in that, I'll post a note.

 Ben-ya-min 35 points

yes this motor does fit into the GWS 64mm fan

 Flyitall 613 points

No sir! Those are promised soon. First sizes available should be for large helis. More sizes to be developed later, if SMC stators are found to be cost effective.(price increase vs. performance increase)

 2Robotguy 10 points

How many ball bearings are in this motor and what is the runout of the shaft? Looking to use this motor in a project and limited runout is import with small horizontal loads are applied.
