• ---FOR 29mm MOTORS !!!---

Use of the Cyclone Power IR500 series motor requires the Cyclone Power Special metal fan to accommodate the larger diameter motor; They went from 28mm to 29.5mm for better performance.  If you have a Freewing Housing you can use that housing instead but with more blades there is more heat that’s why the other housings are metal.  There is less than 7 grams different in weight between plastic and SMF.
