Fellow AHPRA member Bruce Georgeson, (AKA: Kosdon Flyer Extraordinaire)
built a LOC Graduator, basically stock...he did fillet Shish-ka-bob skewers
to either side of the fin tab on the inside of the airframe....NO
fiberglass, ANYWHERE...it's been flown more than a dozen times on Kosdon
I800's...29mm...200lbs thrust for .6 of a second. He's had to replace a few
upper pieces of the airframe due to zippers and such, but the fins have
never come out.
