Lament for the C11-0

It must be assumed that Estes withdrew the C11-0 due to lack of demand.
But that doesn't stop me from being frustrated.  It is a perfect booster
for mid-sized model rockets (BT-55, BT-60).  It has plenty of thrust to
get things moving with authority, but it stages at a "fun" altitude, low
enough to see what's happening.  It's sort of today's B14-0.

I have several rockets I use it in.  Yes, they can all be flown with
D12-0's instead, but I find the combos of C11-0:C11, C11-0:D12 and
C11-0:E9 to be fantastic staging flights.  Yesterday, I flew my Tuber on
a C11:E9 combo, and it was awesome.

Maybe if there's enough demand, Estes will bring them back.

Everyone should fly something staged this week...

Doug,

Go out and pick up every one you can find. Stock up as much as possible and
you'll be able to enjoy them for a while yet. I did that with A8-0's and
still have about 60 or so I use for special flights.

Insert standard comment about not using no longer certified motors at NAR or
TRA launches, or where prohibited by state law...

       The problem with governments is that citizens need to keep
       them on a short leash; unfortunately the nature of the beast
       is such that governments can usually arrange it so that only
       they hold their own leash.

Add new standard comment about lobbying NAR to change the rules to allow
such motors to be used unless a reasonable, rational explanation is
provided...

Has anyone approached the proper NAR people - probably either S&T or the NFPA
rep - in a positive and helpful context to discuss such changes?

I started a previous thread trying to gauge people's feelings about it.  
I also plan on talking to folks at NSL.  I then plan on submitting a
proposal to NAR.

Yes, more than once IIRC.

Someone should bring it to the floor during the next association meeting.

This would probably require a change to NFPA 1125 (It might not, I have never
read anything about this document other than what is posted in the ROP and ROC
documents.) which is currently in the middle of its 5 year revision process. I
just noticed that the Report on Proposals document is now on the NFPA web site.
If you want to see what was proposed, and what survived the ROP stage, go to:

http://www.nfpa.org/Assets/Files/PDF/ROP/1125-06-ROP.pdf

If you want to make some other change, you have to wait five years for the next
revision cycle.

Doug, will my Tuber look exactly like that when it is built?  Not bloody
likely  :-)

Hi, Tad,

NO.  In all likelihood yours will have the correct nosecone :)

When I lawndarted Tuber2 last fall in Windom (on its maiden flight no less), it destroyed the only thing salvaged from the original Tuber - the oft dinged nosecone.  Hence I made this new one, but kinda got carried away on the lathe and ended up with a decidedly different looking nosecone.  Don gave me a new one, but I didn't get it finished in time for this weekend's launch.  

I'm sure you'll enjoy your Tuber.  Everyone who gets one receives good fortune :)

Doug

How big a fortune are we talking about?
