A wonderful thread, I'm sure many people like me read it and feel too humble to comment but I would just like to pass on my thanks, for what it's worth to you guys who walked the walk and took the war to the enemy. I don't know Cliff but best wishes are sent.
Danny we have a two seat Spit at my flying club and the CG problem was solved by moving the front cockpit forward by around 19 inches if memory serves me correctly and making the fuel tank smaller.
