Could someone give me a synopsis of Richard Johnson's test and opinion of
the Sparrowhawk from his presentation at the 2005 SSA Convention?

Raved in particular about smoothness of wing skins (smoothest he's ever
measured, and this one was several years old). Laminar flow nearly all
the way to the trailing edge, top and bottom. Measured performance less
than expected (~29:1 LD), taped on his trademark sheet aluminum wing
fillets, performance noticeably better (~31.5:1), figures more
improvement with properly designed fillets. Very impressed overall.
