karl, I loaned a guy my Dayton 1400 watt focused-heat gun once without knowing what he needed it for. He used it on one of those model planes, and destroyed about $50 worth of materials. Just curious, what do the smart modelers use for heat-shrinking that medium? My field only ever heat-shrinks electricals.
gegkorp, 20 mph really is flying if they're the foils they used to race near my house then, they drive knelt down on their knees on top of them, in front of 15-20 hp. outboard motors. Foils about 6' long, 2.5' wide, 35-40 mph top end but nobody that brave and stupid.
Denny, I like the 10-pennys up through the seat in lieu of side bolsters, mechanically very sound. I would recommend not straightening the bent nails for that, blubber-butts a little too squishy to hold snug onto straight ones.
