Mark, you're not wrong about the development time on Steve Arnold's diesel RV-9A, but as you know about to fly so it wil be worth it in the end.
Vans are developing a 2-seat aircraft with a Rotax for the US LSA category, namely the RV-12. I imagine in the fullness of time we will see it over here on a UK PFA permit.

Mark 1's RV-4 is Red and looks a total nutter. I imagine it's very easy to have a "Mr Toad" moment with. Poooop poop!
