Newly designed high efficiency little motor-23g,thrust 320g, hand winding


The ELE C20 motor is a newly designed high efficiency little motor by elemodel
company, it weighs 23g, thrust force is 320g, and have a good choice on KV
data, respectively are 2100KV, 2500KV and 2900kv, working current is 6-
8A,EP5030, the coil is specially hand winding, so I believe the new little motor will surely arouse intersting and
curiosity among the guys who eager to use lighter and higher efficiency
motor on their airplane.
In order to get more exact datas of the motor, we
welcome the guys who are interested in the motor to test the motor
professionally, the shipping fee is $9.9, the motor is for free,we need 5-10
professional and trusty members on RCGroups to post their test result on the
forum. guys who accept my offer, please feel free PM me.thanks
cheers! below are the photos of the motor

if someone needs propeller and propeller saver for the test, please add $2.9 to the $9.9,thanks

I'm up for it - but I'm still waiting for the 460FX to arrive!

Cheers, Phil

Edit: I hope I have enough tiny props - the 2100Kv might well run a 5x3 at <8A, but to keep the 2900Kv below 8A may need something a lot smaller, I imagine.

With a 4.5x4.1 an LS Park Jet (~2800Kv) I tested drew 7.40A @ 7.1v, and 14.15A @ 10.7v.

oh, im interested, I'm buiding a small airplane that needs a small brushless motor like this. this could be a nice fly-test platform. just as well, I could do bench testing for various props and accu combination's, timing settings and whatnot.

Dr Kiwi, I think the 460FX motor will arrive you soon, the hand winding motor will give you a surprise! thanks

I am willing to be impressed by it! It will make interesting comparison with the hand-wound 24g Komodos I'm getting for testing (though none of them are such high Kv!)

Cheers, Phil

I signed up to test one of these motors and sent my money by PayPal. I am going to try it out on an f-15 profile foamy. I am hoping to run a 5 or 6 inch prop, so I will need one of the lower kv motors I think. I hope it will work for my application.

Count me in...


Yours sincerely will do some testing of this little shiny minibell. (babybel... )

Thanks for the opportunity.

I've already stripper my aerocat, waiting for the babybell...
Or a Pushy-Galore, designed by Theo Coenen.

Put me on the list to try out a 2100 kv motor. I'm living at 2000 feet altitude, so I'll be able to provide a slightly different datapoint.

our Paypal account:[email protected] and if you need some other items
such as servo, ESC and accesssories on our website, but not too many,it depends on the weight,please feel free to PM
me, we will send them out with the test motor without adding shipping fee.
Please PM me your address, name and telephone number,
you will be the third person to whom we send out the motor.thanks

Hi thanks every guys here for their interest, support and enthusiasm on the
ELE C20 motor, I'm sorry that we can't send every PM a motor.
and also I must explain something clearly about the ELE C20 motor: first, the
data of 320g thrust is achieved from ELE C20 KV2500,3 cells Lipo, not from
KV2100,3 cells Lipo. second, three motor with different KV would be a totally
different test result. the third, I forgot to tell the largest advantage of the
motor, its work temperature is lower than any other motors when operating
on high speed. scalding hand will never happened with this motor. belows are new photos of the ELE C20 motorthanks! .

How much thrust do you expect the 2100 kv motor will generate?

Giving "thrust" with no reference to pitch speed is meaningless - I'll bet anyone could get 600g thrust out of any of these, using as a ridiculous example something like an 11x2 prop, but pitch speed would be so slow that no plane could be flown. Or you could get only 100g thrust, but at 80mph with a tiny high pitched prop!

Generally though, one would expect the maximum power output of the 2100Kv motor to be a bit less than that of the 2500Kv motor, since the latter should be able to cope with higher amp draw.

By the way, Hanks - nice neat windings with good size wire, though isn't there a LOT of space unfilled!
