Spring in the Air 2022
Day Two was promised to be better but by 12:30PM, the fog still hadn't burned off. Oddly, if you went 15 miles in any direction, the weather was nearly perfect: rising temps and puffy clouds.

Lanzo Airfoils (Bomber & R/C Stick)
Confusion persists about Lanzo Airfoils. E.g: The Puss Moth has been published with a flat bottomed and an undercambered airfoil. When the Bomber was approved by SAM in the early eighties, it was assumed to have the same airofoil as the Record Breaker because the Long-Center Section version has the same wing planform. This was not the case. The R/C Stick did not specify an airfoil and variations abound.
I found this blueprint in a box of tissue scraps left by the late Bucky Walter who worked with Chester Lanzo at NASA. I never met Mr. Hoffman but I'm guessing he was also a colleague or, at least, a fellow member of SAM Chapter 39.
