in my opinion , it is the best turbine when used with 8s 5000, but with 6s 5000 make the basics fly only.

Dieser EDF ist wunderschn verarbeitet. Er ist nur schon zum anschauen und anfassen ein wunderschnes Schmuckstck. Er ist perfekt ausgewuchtet, und er tnt mit seinen 12 Blttern richtig gut. Bei mir bringt er die Werte die oben angegeben sind nicht ganz.
Ich habe ihn mit einem 4000er 6s 60C Lipo getestet. Bei 115amp bringt er 3Kg Schub.
Ich kann diesen Fan nur weiterempfehlen. Ist mein lieblings-Fan.

Hi,
I didn't Maiden it yet, but here the first Static Test on this Item on my Aermacchi MB339 FlyFly with 6S 5000mAh 40C and SkyWing ESC 150A
with a fully charged Lipo i got:
Peak Amp: 100,51
Peak Watt: 2154,65
Sound is Amazing, and Balance is the Perfection.
I struggled a little in order to FIt the Fan in my MB339, it's big and I had to sand a lof of foam, and re-build the Thrust Tube.

Beautiful workmanship. Only one very minor flaw in all 3 units I bought. If you remove the tail cone, there is a small edge of flash (sharp) on the leading edge of the guide vane. Easy to remove with light sanding, but was present on all 3 units I bought, suspect it is some sort of tooling mark. Otherwise, 100pcnt.... Worth buying just to admire the workmanship and for display. But mine will be going into an L59!

Runs great but not with the Hobbyking SS Series 190-200A ESC as you can see on the video.
The EDF ist great but you need the proper ESC. I think i will replace this ESC with the Hawk BL 120A OPTO ESC.

Excellent workmanship and engineering. Comes extremely well balanced. All one has to do is to apply some threadlock on the front motor cap and the back screw-on housing half and solder the bullets on the motor leads. No need to spend time and effort in balancing. It runs smooth as silk. The metallic resonance sound goes away at high throtle settings.

My thrust stand test of this (1900kv 6s Version) on 6S brought somewhat unexpected results.... The amps were higher than expected. I first tried without an inlet lip to have a baseline with the manufacturer's spec. Used a 5000mah 6S 65-130C nano-tech with a 100amp DLUX ESC.

Peak readings from the watt meter....
22.16Vm
127.87Ap
2967.8Wp
3.1 Kg

I believe that it is likely that the thrust measurement is understated on my stand. I had to make some quick mods to the stand to accomodate this long and wider than normal housing.

It settles down to about 22.5V and 117Amps for 3Kg of thrust.
Obviously, with less capable batteries the amps will go down to the 95amp spec.

Thumbs up even at the relatively high price.

I have uploaded a video of the test in the "VIDEOS" Tab.
