I have build a H9 showtime 4d 90 and installed a saito 125 on it. Now i am thinking about what spinner and prop to use on it .
Any help and suggestions please.

Spinner diameter is determined by the airplane's cowl. As far as prop, 16X8 is what I'm swinging on an Extra 300. For 3D, you might want to go bigger diameter, lower pitch.

Thank you. I mesured the cowl and it is 65 mm and bought 65 mm aleminium spinner. For the prop i will stay with the saitos recommendations for 125 which is 15x8 apc .
Thank you for your input.
