That's BEAUTIFUL! Radial engine. (Would kind of look like a little Zero Fighter with different paint.)
Performance? What led you in that direction? How'd you do it? Was it (excessively) difficult? How'z about some video of her? I'd like to hear what she sounds like.
She's an award winner for SURE! (I'll bet we see a write-up in Sport Aviation.)
Congratulations! (BTW, I'm available for "ballast" if you need to test her at a heavier weight.)
Back in the stone ages ('98) when I started my 4 it was the coolest looking plane on the planet. I figured that i'd have her flying in about 6 months and that all who saw her would drool and beg for rides. Next thing I know guys start turning them into Rockets and suddenly my 4 is not the coolest plane.
And now this!!! That thing is the baddest airplane I've ever seen. Great job!
