Customer Reviews

Blades rubbing shroud? Review by Henry
After some research, I found that the blades rubbing the shroud is actually normal. The factory tests these and the reason they rub is that at high speed the plastic blades stretch and rub the shroud! It's advised to simply break in the EDF by starting slowly then increasing eventually to full throttle, doing this several times, and by doing so the blades will rub until they no longer make contact so sanding isn't necessary.

Very good combo! Review by Hawk
Bought this combo several years ago for my Exceed RC Mig 15. Have not tested the fan unit because, like another post mentioned, the shroud has rub marks from the blades. I torture tested the servos with a 6 volt Rx pack and YTV servo tester and was pleasantly surprised at the results. All four servos were very accurate and centering was perfect! At no time did the servos overheat, in fact, they remained cool to the touch. I used 6 volts, although the recommended voltage is 4.8, because if they were going to fail they would do so with the higher voltage. All passed with flying colors! When the day comes where I can sit down and get the fan shroud sanded I will post the results. (Posted on 12/6/2017)

Good Review by Thomas Novotnak
Only problem, loose screws in box, stuck to motor magnets. (Posted on 5/5/2017)
Great but needed sanding Review by Nolan featherstun
For this price it produces almost unbelievable thrust but the housing needs a TON of sanding otherwise the turbine will rub or even jam. Great performance but be prepared to watch a movie while you sand down the housing because it needs a ton of work. (Posted on 4/20/2017)
