LOC/Percision Forte fin Question...

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.

If you have not put on the rear centering ring yet, you can put a puddle of
epoxy on the internal fin tabs. I constructed my Forte that way, with an extra
CR for a baffle. Rocket has flown several times on an H180 and once on an I200.

Triple the shock cord! Use more epoxy! Always fly straight up- you need the
exercise anyway.
