Forget WHO is flying (friend, rival, countryman, flier from other nation) Forget WHAT is flying (2-stroke, 4-stroke, electric, turbine, rubber-power) LOOK ONLY AT LINES DESCRIBED IN THE SKY! (and the precision, smoothness, positioning, and size) Bob Skinner 2006 Thank you! Peter Uhlig, January 2008
