Very interesting, Dane...'clockwise'. Back in the '40s, there may have been more guys flying CW than had caught onto CCW.
Anyone recall why the 'switch'?
When I started flying 'sport', I'd get inverted...chickening out halfway thru an outside loop...A voice inside my head repeated, "Down is up, down is up..." Very unnatural.
BTW, are these Perkys built with the .15 size limit? Looks like some larger engines here...
