My younger brother had that supposed 2-stage Apollo setup. He may still have it; I dunno.
Never could get it to fly nearly as well as the claims.
The cheap hand-held teardrop shaped ones most often flew better.

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, TURMOIL, FIASCOS, and HAVOC !
