It begins, these are the test cutting patterns (with some alternate sheet width choices) for a 14 inch span F22 Raptor with a 1/8th balsa wing and the rest mostly 1/16th sheet balsa for TSP L2 or L3 depending how the weight turns out. Progress getting the drawings in shape has been very slow of late with the holidays and visitors. There are still some main elements yet to be decided but I need to start building something soon or I will procrastinate for ever!

Wing core sections joined up, the edging and then sanding to section comes later, that's it for today.

Mark Digby designed a very tasy and sophisticated semi-profile 'YF-22' in 2007.









When it flew it really looked the part, but it was quite 'twitchy' and I don't think either Mark, his father John, or me (I had a go too) could trim it out to our satisfaction.
A study of the plan shows that the wings and tailplane are essentially '0-0' with some 'up' elevator. Adding a bit of proper 'decalage' could eeasily solve the model's unpredictability and would be an interesting experiment. :) B)

If you would like to build Mark's YF-22, given the caveat above) please ask me for the plan pack.

Howard's 'take' on the F-22' will of course be different, and I look forward to developments!

Just a thought: if Howard is building an F-22, how about one of us builing a Su-57?





I've been searching for a 'proper' 3-view to build from .... no luck yet, but I'm sure it will make for an interesting model. The build should not be that dissimilar to the F-22. :huh:
