Stumbled across this thread today and brought back many, ahem, childhood memories! I recall Perrin as a hangar rat at Sportair, learning his aerobatic craft in the RF4s. Flew some pairs displays with me dad, who was then the CFI (kind of precurser to the infamous & fabulous Unipart displays).
Many ex Sportair names cropping up in this thread! Though sadly some departed...
Merry crimbles to all
