I was reading the Aeroworks flight results on the new version of their 29% Edge 540 with a Brison 3.2 and they used the Menz 20x10 standard. They seemed to like this prop so I think I'll get one and see.
I also have a BME with a Mez. 22x8 on the flat tail Aeroworks Edge and it works well also and quiet which I like. I may try this prop also and compare.
Got some good replies and I thank all for the suggestions.
