The motor arrived in a rather plain black box inside a shipping box. It had no instruction manual or pictures.

The pictures showing the disassembled motor are from their Website which is linked in the box to the right of here.

Included Items

Features:

  • First-class mold design,ensure the blades have perfect dynamic balance,the blade fits nicely in the duct, sound effect and efficiency value are comparable to all metal duct units on the market.
  • FMS pioneering thermal design,in does not affect the efficiency of the case,ensure the motor's normal working,no need to worry that the motor heating will affect the life and performance.
  • Reasonable structure design,you can arbitrarily choose different manufacturers motor,this item can e assembled to all the 90 ducted airplane,no need to make too many manual changes to the aircraft.

Assembly

No assembly was required as the motor came fully mounted into the ducted fan unit. The fan consists of 12 blades that are composite and rigid. The unit should mount into a plane designed for a 90mm ducted fan without much difficulty but that was not actually tested at this time. I was able to connect the motor to a High Voltage 120A Castle ESC that I have from the plane previously intended for this review.

Bench Test

I was able to bench test this motor and fan combination by mounting the motor to a board that served as the bench mount. I was safely able to run the motor up to about 3/4's throttle using the Castle ESC, a Spectrum receiver and Spectrum DX-9 transmitter and a 6-cell Roaring Top 2700mAh 35C battery pack and a 6-cell 5,000 40C battery pack. the motor ran smoothly but I didn't trust my homemade motor mount to continue to work if I supplied full throttle. the operation of the motor and fans was smooth and indoors in a small room it sounded very jet like. Outdoors the sound will still be nice but not as powerful as it was in a small room. The price of the motor is very reasonable and I was very pleased with the unit in the limited testing I was able to perform. I ran both batteries through the motor at half throttle and 3/4's throttle several times. When my weighted down homemade mounting bench on the floor started to move I ended the testing.

Conclusion

I have been pleased with my limited results and I look forward to further testing with an actual plane. the combination looks clean on visual inspection. The blades spun nicely from low to 3/4's throttle and I have no reason to believe they won't work well at full throttle. Since it doesn't look like I will be able to afford a new 90mm EDF before this summer I wanted to share this mini review and let pilots know about this new motor/fan combination for 90mm planes.

That is a pretty thirsty set up for 6S, price sounds fantastic if you believe 3.5kg thrust with that tiny motor. It should sell like a hot cake, I like to get one just to check it up in one of my foamy test bed prototypes.

Quite.

No thrust measurement either.

It's not a 'review', it's an advert. As so often.
