The Drifter flies almost as high as the Astron Sprint due to the thin fins and boat-tail. If it used the elliptical fins it would go as high as the Sprint on the same power.
You will be very surprised how high it goes on an A8-5.
For flight use upper stage engines-it needs the extra coast time.
1/2A6-4, A8-5, B4-6, B6-6, B8-7, B14-6, B14-7, C6-7.

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 !
