Mark, fear not!! The graduator with just some very modest mods will take almost
anything you can dish out!! Use 1/8th inch dowels epoxied to both side of the
fin tab inside the airframe, then use two part foam from the top centering ring
all the way to the bottom of the rocket. Once it hardens, sand the foam down
far enough into the airframe so that the rear CR will fit in. My buddy built
his graduator stock then added the dowels to the fin roots. He didn't even use
the foam, and he flies it Kosdon I-800's. 200lbs of thrust, 430Ns, .6 second
burn time. These motors are incredible, and in the Graduator, the rocket just
vanishes from the pad. It's truly AWESOME!!! In a nutshell, the Graduator will
stand up to a lot of abuse if mildly modified.
