I had built both the Centuri Magnum Sprint and Magnum Hornet kits back when released in the early 80's. They both had plastic nose cones. The Sprint used the same cone as Vigilante/Skybolt/ Cobra 1500; PNC55AO. The Hornet used the Cherokee-D/Nike-X cone; PNC55AC.
My Sprint POWR-PRANGED on it's second flight in ~1986 due to an offset thrust D11-9.
Incidentally, every time I flew a Cherokee-D or Skybolt on a D12-5 or D11-9 I got them back. Every launch on a D12-7 I lost them. 6 Cherokee-D's and 2 Skybolts.
Actually got a Cherokee-D back from an old E-kaboom15-8 flight but replaced the idiotic 18" chute with a streamer.

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, and HAVOC !
