Hmmmmmmm...
Saw said ultralights in YPTN overnight last week and know the two guys you are talking about! Funny this thread should appear cos the one guy (accent) was hitting me up for a cordless drill to tinker with his lil one cylinder engine as it was having a few hiccups.... Now dunno if this occurred before or after the encounter this thread is based on BUT their attempts at "Pilot Approved Maintenance" really made my day!!!
Obviously they never found the drill they wanted....
