So here is a question:
How is the 51% organised in the UK? Basically in Canada if you drill and rivet once on the wing that wing qualifies as home built. Some of the kits that qualify as 'Amateur built' in Canada (the equivalent of 'Experimental') have the wings and fuselage completely built except for one surface panel on each. Since nimble professional fingers (sometimes in the far East) can build things far, far quicker than your average amateur the 'Quick build' kit is very attractive.
I spent 850 hours building my plane from components (a kit) and it was painless, I'd happily build again, maybe an RV quickbuild or something very like it.
