I used a clear payload section similar to the Astron Constellation on top for "normal" flying of my Astron Delta.
I also had a large "Farside X" type payload that got flown as well.
Apparently Estes thought they needed those huge fins with the large un-aerodynamic Camroc on top in order for it to fly decently.
This was obviously disproven with the very small elliptical fins found on the single-stage Astron Camroc Carrier, which looked as though it fell at least 50 feet out of the UGLY TREE, but flew well.
Those huge fins on the Astron Delta make it a NASTY weather-cocker in anything but very light winds.

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 !
