Hey Mike...
You know... I didnt see any thing about this in the rules, but I have two kits I was given several years ago as gifts, A Spad VIII and a Fokker DVII in what I would consider to be roughly 1/32nd scale. What I'm a bit hestant about is that both are balsa and tissue model kits. They are models, and IMO more in line with how the actual air craft were made, but is it acceptable for this GB? If not, I could look around for a styrene kit, and yes the WingNut kits are Sweet! Very nice and well engineered kits. I'm not the best with balsa, but have made some advances (skill wise) after buying and practicing some tips in a book I found on the subject. Not that I'm into the balsa that big, but would like to try to improve my over all skills as a well rounded modeler! (grin).
That was my thoughts as per now.
