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.
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.
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...
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.
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...
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?
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- will the number of blades in the EDF unit make a difference and if so how many blades (eg. 4 or 5) would be safe with 4S? thank you for your reply
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 :}
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.
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
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...
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.
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.
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
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
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... *-)
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$.
helo everyone, i know this motor its not suposed to use a propeller but a EDF, i just tryed it, with the folling setup, 5x5 prop. 1300mah 3s 20c bat. and a 30amp esc, well the esc started to burn , it actually got on fire as i went to 1/2 trothle, so i tryed it with 55amp esc, it was ok, but esc is getting hot, maybe because it was not guething any fresh air. i dont have a wats metter, so should i low the prop to 4.4x4.1? thanks
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.
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.
I recently bought two of these motors to run on a twin. One spins freely by hand, the other spins, but not nearly as freely as the first. On the bench it doesn't seem to run quite as smoothly. Is there something wrong with one of my motors? At this price I have no problem buying another one, but if I don't have to I won't. What will cause one motor to spin freely and another to not?
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 ...
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.
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.
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)
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.
1 thumbs up!
Bought 2 of these &one has a slight vibration(hence 4stars). These seem comparable to the the blue Turnigy EDF motors but I prefer these. Comes with all screws & 3.5mm connectors, heatshrink etc & 3mm shaft. They fit perfectly with these HK fans www.link to give 351W WITHOUT intake ring & 380W WITH intake ring on 3S static peak & I'd say roughly 500g thrust, more with a thrust tube :)
