Great modification to any 12 blade 90mm FW jet

I have now modified approximately 8-10 of my planes with these motor and have found to be at least 20% more powerful. They give to the plane an authority of which was not with the 1550KV. I have not found any that needs any type of adjustment or return. They just "WORK'.

Excellent motor!

I have now about 10 of these motors and all have been a step above the average. They are reliable and powerful. They really make a difference in the way the 90mm FW planes fly. I would recommend highly if you want the performance and reliability over the factory norm.

Good Power

This is my second motor. The first one worked great until an 80% throttle pass down runway and motor fried in less than 3 seconds. It over amped and over heated the ESC and fried it too. I am running it on a Castle 130 amp ESC with a HET 9305 fan with 5 blades 8s. It usually pulls about 95 amps full throttle.
