Dave,
I have been thinking on the top cowl part.Was thinking a hinged piece where you see the deflector in from of engine. I am the type whos always working on engine and with pump mounted low with belt drive and poppet or two at the shut off I will have to have fairly quick access to that area.
I've been up in the air on wing few times,but I like the look.My first design way back had a wing but was more laid back mounted low and was up and back from cockpit. I hat low wings they hurt when you ram your head into spill plates.Yea been there cpl times.
