That is super cool! Now I see where the screen name comes from. I actually saw quite a few EJ powered RVs at Oshkosh last time I was there, and have followed the various companies who have produced conversion kits for airplane use. And I have actually flown an RV6 as well as a pitts S2 and I have ridden in a family friends skybolt. I would love to build a subaru powered airplane one day, but I don't know that I would ever have the time or money. That looks like a lot of fun! How does the acrosport 2 compare to a pitts? Is the visibility better? Is it easier to fly?
