Transatlanticflight,

What are you designing or building? There is a very knowledgeable group out there that could probably help but with all the variable you need to narrow it down. I have some examples I build my heavy iron WWII warbirds with typically 1 deg. right and 1 deg. down thrust. My WWI dawn patrol stuff has 1 deg. right and 2 deg. down thrust. However, my Pietenpol Aircamper has 1 deg. right and 7 deg. down thrust. So it shows you how dramatic you can go. The Piet with that 7 deg. down thrust is scale by the way and the airplane needs it. Every Piper Cub I have flown, which is a similar configuration to the Piet, could have used a lot more down thrust. I just never thought that any of the designers knew what they were doing to make a more power neutral airplane that didn't climb like crazy when you poured the coals to it. Leo
