This is the new version of the 90mm Alloy Dynamic Power Series EDF unit.
The construction of this ready to fit and fly 12 blade unit offers a distortion free Alloy housing, correctly profiled stators, aerodynamic motor shroud/heatsink and an efficient pre-balanced 12 blade impeller. Resulting in a combination of huge power, with reliability and efficiency. The unit is factory dynamically balanced resulting in a turbine-like smoothness.......And THAT turbine sound!
This superb EDF is totally pre-assembled complete with motor, simply fit to your model, set the ESC motor timing to high and tear up the sky!

Dieser Impeller wiegt DOPPELT so viel wie vergleichbare 90mm EDF.
Ansonsten luft er sauber und hat ein angenehmes Rauschen.
In meiner Mirage leider nicht zu gebrauchen.this fan is great..cool sound but could only get 1700kilogram thrust not the 3kg as stated with a 6s 4000mah..
put the fan in a cmp/hobbyking T-45/hawk without the intake duct on ,flying weight 3300kilograms flies greatyes this is a DR.Mad Thrust EDF as confirmed by mail by HobbyKing.
So HobbyKing you have to change the pictures and the description, because a DPS(Dynamic Power Series ) means it is an RC Lander EDF !!!I used this EDF setup on a stryker. I had paired it with the Redbrick 100amp esc, and used a 6cell lipo 5000mah. I know over kill. This setup had so much power it split the plane in twoTerribly heavy and only turns low 30k on 6 cell.. Lousy thrust! Buy a good plastic fan instead.. Looks cool setting on the bench though! Best stay away from this..Aprs montage sur un mirage 2000 en 6s enfin le premier vol et la puissance est au rendez vous fonctionnement nickel!!!!!!!!!!!! Super produit .......I received this unit a couple of weeks ago and installed in a 90mm viper. The dynamic balance that is claimed for this fan unit must be true because this fan runs with no vibration at all, extremely smooth. I do have a couple of issues with it though. One of the stator blades was cracked where the bolts go through it. Doesn't appear that it will go anywhere. Also, I was unable to get the 3.1 kg of thrust that is claimed. The max thrust that I got was 2.1 kg, however, it was mounted in the viper when I checked it and the reduction in thrust could be due to the ductwork of the jet. Still, a little disappointing. The ducts are rather large and should not have reduced thrust by 1 kg. I was using a HK 120 amp speed control with a 4500 mah nano tech battery. So, it appears to be a nice unit, fairly well made, but somewhat disappointing in the thrust output and a little heavy as well. I wouldn't have minded the weight penalty if the thrust claimed was there. As it is, I have a heavy fan with little thrust, not the best combination.Super produit j ai effectu les essais en statique rsultat 6s 84 A 1754 w avec 75 pcnt de gaz tant limite par mon variateur
