I have 2 of the Commonwealth 29mm HPR upgrade kits for my next two Saturns.
Large HPR Chute, heavy plywood centering rings, heavy wall 29mm motor tube, Heavy duty SCALE resin fins.
No mamby pamby slip on clear fins either. You use a proper amount of genuine LEAD in the nose for stability.

Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, TURMOIL, FIASCOS, and HAVOC !
