The hellcat is actually the 1000 series blown to roughly 90"... (300%)
The P-40 above it in the photo is a 500 series blown up to around 80"... (400-500%)
Both of those planes were built all balsa, and were EXPENSIVE... Learned me a lesson... (later planes were built with 1/4" pine plywood... I can now build em blown up cheaper than I can buy the kits...)
