Can I downscale a Spool Rocket? Will it back tumble like the full size CD spool rockets? Had to find out..
My Micro Spool consists of two 1-1/2" x .040" Clear Polycarbonate discs covered with adhesive backed Party pack metalflake mylar. core tube is standard T2+ with an outer sleeve of T2++ between the discs covered with silver adhesive backed mylar. epoxied the discs at the ends of the motor tube with the spacer sleeve epoxy mounted between the disc. 3/16" T2 motor stop allows the MMX-II motor to extend 1/8" for the 1/8" projecting T2+ motor tube allowing friction and external taping.
a simple .052" hole beside the OD of the core tube aligned in both disc's serve as Launch lugs. Total Ewt = 3.9g LOWt: 5grams. Max altitude 25feet and yep at apogee it flipps backwards, spinning wildly all the way to the ground. KEWL in any size
