Hi Noflaps, I am using a YS-140 Sport with a Hyde Soft Mount purchased from Central Hobbies. I would like to try a Graupner 3 blade which has a little better reputation than the Master Airscrew props. I think I found a plastic 3½ inch spinner on Skyshark web site. I have always use APC 2 blade but want to try a 3 blade.

Best of luck,
Arnold
