Paul,
So that means they were using normal APC props?
kamlooper,
Why don't you try Turbocad? They have a free version that you could download. And it will allow you to print full size plans into several pages.
Anyway, I decided to get some 9x4 and 10x4 APC props to test on my os15fp. According to one of the sites i visited, the 10x4 would produce 1.1kg of thrust and the 9x4 would produce 900grams thrust.
