Angus, do you mean Christoph Jaquard?
I know he owns a Spit XIX. It flew with a dual prop, but this was changed to a 5 bladed one this year.
If yes, he is also the first guy whos FW190A8/N has ended its flighttests and is now displaying it on airshows. He was in La Ferté-Alais and Duxford this yeas and i will hopefully see it on the Hahnweide in September.
About the different ailerons. I reviewed a lot of pictures, but it was hard to find any that really showed the aileron to flap changeover. I found a few good ones along the leading edge for the earlier versions, which showed that there was straight line, only the trim tab extending past the leading edge. For the third type with the new trim tab postion there was no real good picture, but the medicore ones showed no significient extending of the aileron leading edge.
