in full size aerodynamics for the V tail to be as effective as the usual Fin and Rudder, and Horizontal Stabiliser and elevator the V surfaces need to be about 1 and a half times bigger so overall there is no advantage.
if you want a really frisky, really frisky, homebuilt have a look at the Davis DA2a.
the only homebuilt aeroplane I've encountered that I would rate as harder to fly than a W8 Tailwind.
