Bei 3S wird der Motor nach 3 min über 130 Grad Celsius heiß und zwar ohne irgendweine Last. Mit 2S habe ichs nich probiert.
I tried this one with 3S and it´s getting really hot. More than 130 degree celcius without any fan or somthing else.
Hello, i dont recomend use it on e-revo VXL. have toasted the original velineon ESC using 2s lipo. it pulls to much amps. other thing is to be carrefull with the connectors, they tend to lose with time.
Yes the diameter of the screw is 2.5mm but i use theese motors in various models and you must make sure that the screw length does not exceed 1/2 an inch or 12.5mm because it begins to rub on the internal part of the motor.
Got a problem!
I bought this to be used with the 3 inch 7 blade fan. It seems that the load gets too high. On full throttle I get 116A and 1133W with Zippy Flightmax 5000mAh. Is the fan too big for this motor or what?? Fortunately I noticed this in just seconds and with the wattmeter attached, so no apparent harm done so far.
I have the same motor, and yes, that fan is too much for this Amp-hungry baby.
I'll try "High-Speed EDF Ducted Fan Unit 3Blade 2.75inch 70mm" ($8.12, currently out of stock), and HET 6904 - 4 blades (not available in this site).
Try also changing the ESC timing setup, I did some tests using a 5*2 prop and got significant differences in amp readings.
In the product description it states the max the motor can take is 50 amp. I always give myself some headroom so 60 amp is the minimum I would use. Turnigy Plush 60 amp is one I own. It has a switching BEC so it can also handle multiple servos. The Hobby King SS series 60-70amp ESC is a good budget servo. You will need to buy a BEC.
It would really depend on how many cells you want too use and what prop you want to run. That will determine how many peak amps you will be pulling, so choose an ESC form there. You'll need one with a built in BEC, if you only want to use one battery, or buy an external BEC and wire it into the ESC battery leads.
Thanks for ALL the input, it is much appreciated!!
Now Mattias makes an interesting point here as I was intending to use these motors with their 7 blade EDF 2.5/3.0".
Now what to do?? I am looking for a high speed motor for the unique sound it makes in an EDF also power for fast flight. I realise that there are many other expensive options if I was to use "Name Brand" stuff but I have bought a bunch of stuff from HK and overall am very satisfied. I have kit forms, the F14 and F16 and want to power these. What have you used to good effect in these planes?
Again thanks for all your help Guys.

P.S. One of these days I will fly my A380!
I just tried it out before sealing up the jet. I had trouble first around with the hobbyking 40A ESC sbec(mystery ice) and it stuttered at first, so I changed it to hard start, and then it jumped to 58 amps just before full throttle and stuttered so I shut it down and put in an Align 60A esc I have. Tried out 2S 5000 40C lipo and it ran smooth right up to full throttle, screaming! So I then tried a 3s 3600 35c and it was smooth up to about 3/4 throttle where it stuttered and was very loud so I shut it down.
2s 5000 lipo, static test- full throttle
3s 3600 , static - throttle – motor stutters at various points in throttle:
I am going to use the 2s lipos until fan and motor are broke-in and tested in flight, and will try 3s after!
Should be OK if kept around 50A.
a friend of mine took this motor with 2,5" EDF + 70A esc + 2.200mah 25C 14.4V battery. he would like to use these in a Mirage but during the test on the ground, after 3 minutes with throttle in the middle, the motor was too hot and it lost rpm. i would suggest you to buy a motor that works below 3700rpm with 4S battery
How many battery cells do you want to run ? this dictates size of prop to stay under 50 amps.
36 thumbs up!
I put this Motor on an Multiplex Funjet with an 80A Esc from hobbycity an an 3200 mah 3s Lipo of hextronik!(Also purchased here) This is an extrem Setup for Multiplex Funjet. I think he is faster than 200 kmh. Aplus

Tested on a bench with a WM400 velocity RC Fan with 3S 3700mA 20C. Max power is above 800W !!!! but probably not suitable for motor's life..... I just tested a few seconds. Will now try on an HET F20 jet with first a limitation to 600W and see on higher power what happens....I will give you information as soon as... Philippe France

I used this motor with self-made water cooling on boat FSR ECO expert with 5000 2s lipo. The result has surpassed expectations. The modern case of a boat has appeared improper for that speed which was given by this motor. On full gas to float it has appeared it is impossible. I am glad to this acquisition and took 2 more that my friends did not lag behind me. Fine purchase.

I use this motor in combination with the following setup: KB28-47-08S plus ZIPPY-H 5000mAh 3S1P 20-30C Lipoly, Haoye 2.5" 70mm EDF fan and fitted this setup into my SAPAC Goshawk foam EDF. It immediately turned that underpowered jet into a speed monster. But the motor shaft is soft, got a lil bent when i fitted it into the EDF fan casing and I also noticed that there is no ventilation hole for motor either. Results? The EDF was scrubbing the side and was making loud noises. Everything else is okay I guess, 5 minutes of full throttle just makes this motor warm, not too hot like other motor I've used, or worse burnt hehe. The supplier should have spare motor shaft's available, in my opinion, too soft! Either make it stronger or sell the extra shaft. Everything else is okay I guess.

This motor is good. Has no cooling and gets hot fast. Not suitable for 2.5 fan on 3S. Melted fan. Crashed. Zippy 3S2P 4400, turnigy 80, 2.5 inch five blade hoaye fan, 2.5 lbs thrust, maybe 100 mph after a dive in a home built 36 inch span twin boom jet. Veeeeeery hot motor. This was just too much load for the higher kv so pick your hobby city motor wisely. It was fun while it lasted though, I may try 4S with lower kv, 4000 range.
