Mercury Alloy 12 Blade 90mm 1900kv EDF Unit (6s)

Mercury Alloy 12 Blade 90mm 1900kv EDF Unit (6s)
Mercury Alloy 12 Blade 90mm 1900kv EDF Unit (6s)

A result of 3 years in research and development these Taiwanese manufactured 90mm EDF units are on the cutting edge of EDF design.

The duct unit is made from aircraft grade high tensile Aluminum alloy to improve performance and help reduce deformity of the duct during installation. The 12 fan blade is the first in the world to use high tensile aluminum alloy, A result of 18 months of wind-tunnel tests and Computer Aided Evaluation. The fan unit reduces high speed deformation by 90%, compared to a conventional ABS or plastic fan.  
All Moto-turbine parts are manufactured using precision CNC machine tools in Taiwan. CNC machining enables a high level of acuaracy in the manufacturing proccess and ensures strict tolerances can be maintained. Each fan is also factory dynamically balanced.

In conventional ducted fan design, the motor is secured to the stator hub while the fan secured to the motor shaft.  During operation, any imperfection in either the motor or fan will cause both the fan and motor to vibrate at a certain resonance frequency.  The oscillation can cause the blade tip to rub against the shroud of the duct.  Moto-turbine’s 3-bearing system reduces resonance vibration by 90%.

1 thumbs up!
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.

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!

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.

Dieser EDF ist wunderschön verarbeitet. Er ist nur schon zum anschauen und anfassen ein wunderschönes Schmuckstück. Er ist perfekt ausgewuchtet, und er tönt mit seinen 12 Blättern 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.

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