12 blade edf
Wonderful company! Never have any
Wonderful company! Never have any issues or complaints! Way to go guys!
Bought this to help me hand launch a Freewing F9 Panther I couldn't get in the air. At 5000 feet it is not enough. I did get it to fly after many unsuccessful attempts but it wanted to stall if I turned too fast or climbed to quickly. I wish I had gone with a 4s set-up. My next project is a bungee launcher.
bolt holding cap on fan
bolt holding cap on fan blade was lose. could have caused a problem. otherwise fan and motor seem well matched
Nice power unit
I actually bought this for an experiment not related to RC airplanes, although I do also fly RC. What I was really happy with was how well balanced it was right out of the box. It ran silky smooth...draws about 55A at full power. I actually just retrofitted two of the same 12 blade fans only into a new Dynam Turbojet, reusing the stock motors. Ducted fans are a pain to balance without fancy equipment, and I did not get either of them as good as this one came from the factory. The motors look nicer than the stock Dynam motors and have a nice streamlining cone on the back. At this price, I think I'll just buy these power units rather than having to fit up the fan only to stock motors and balance next time. The thing has insane amounts of thrust in testing. I would probably set a maximum throttle limit on the Turbojet, as these push more appropriately for a fighter jet. You pay for it in amps, though on 3 cell. A twin engine setup probably ought to go with 4 cell if you want to use at full power. My experience is that it is really hard to find a battery in the 2100 mAh range that will support much over 60A without a lot of voltage sag and excessive battery heating. These things would definitely be the way to go in a fighter jet type model. Only con...they come with the inlet cone glued to the unit, where it is separate if you buy just the fan without the motor assembled as a unit. That was important for the Turbojet, as I had about a 1/2" space between the inlet cone installed on the front of the nacelles and the fan unit in the stock location. I filled with spackling, but would probably have to modify the nacelles to accommodate the fan units more forward if I had used these.
High Performing 3S EDF Motor
Significantly better performing motor over stock 3S motor. This motor does affect flight time. Only expect 3.5 minutes on a 3S 2200mah battery. Also recommend something higher than 35C 3S batteries as the amp draw on this motor tends to puff out 30 and 35C batteries. I've used Admiral 3S 35C 2200mah and they can handle the draw however they still get quite hot and do puff some after each flight. Overall very glad with this purchase.

What an Upgrade!
This 64MM fan is a great improvement to any of the 64MM Freewing models! It changes the sound from the "whine" of an EDF to a more pleasing and realistic "whoosh" very similar to an actual turbine, and the thrust output is much increased. Now I'm looking at other brands of my 64MM models to modify as well! Great product!
