LeadSled, as things now stand that US Spitfire look alike is an Experimental Amateur built, not a warbird, just because it looks like one.
I'm well aware of CASA's antipathy to Experimental. Please pm me.
Also well aware of how the organisations like SAAA, RAAus, GFA etc love getting CASA to force people to join the organisation and give it money. For example the stupid SAAA maintenance course which teaches nothing about maintenance but is all about paperwork. If paperwork is what is wanted a written checklist of what is required will suffice.
Just as the SAAA business model was a brake on amateur building the GFA model is a brake on soaring. Lovely activity but GFA has made everything in it compulsory or prohibited.
