Thanks everyone, but I'm going to drop this idea for now. The Virus on a BMAA permit, limited to 472.5 kg, is a complete non-starter because not being able to use its full load potential would be a complete waste of money. As I've already indicated, an EASA permit isn't an option for me.
Years ago I considered the MCR-01 and reached the conclusion that it's too "delicate". Read through the LAA TADS and look at the comments on the flap mechanism as well as other mandatory items to see what I mean. I would also want a VP/CS propeller and the Arplast isn't my "cup of tea".
So I'll bow out and spend time thinking about other options. Thanks again.
