Mike Arnold has a couple of very efficient airplane designs to his credit, and since the Cassutt racer started this trend (it's ALL Carl's fault!), let's stay with race planes for one more month.
I remember seeing drawings years ago for a super sleek racer designed to meet the rules for Formula One--specifically racing with an engine displacement of no more than 200 cubic inches. This is his vision brought to life.
"Endeavor," is a Formula One racer with fantastic lines and impeccable finish. If you look at the reflections in her skin, you'll see just how smooth a surface was achieved. I shudder to think of the hours spent making the aircraft this perfect, but that's what racing is all about--getting the most out of the air while disturbing it as little as possible.
The LOOTM for September--the Arnold AR-6 "Endeavor." Enjoy!
