I like the chrome-mylar wrapped, pre-finished main tube of the Centuri better than the Estes re-issue.
Also, it makes no sense to me that the Estes kit ONLY recommends the E30-4 engine.
It will surely fly on the Estes D12-3, RMS 24 E28-4 and RMS24 F24-4.

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 !
