So much Hype if true on the P-40.
Also, Holy crap that jet is HUGE! You really enjoy seeing just how far you can push foamboard! I'd have to imagine after a certain amount of size and power, you'd start running into issues with foam-board simply not being strong enough to handle the stress loads, Do you have a method of maddness to calculate the loads the foamboard can take to determine when and where to reinforce and with how much, or just run on pure skill, practice, and experience when building out models at this size!?
