One could not pay me enough to even consider living in California.
WAAAAAAAYYYYYY too many laws/regs and liberals. I'd probably spend time in jails just for voicing my ultra conservative views. The closest I have ever gotten and will get to that state by choice is Las Vegas, NV.

Tell me about it. I am located 2-3 miles south of the boundary for the Witch Creek fire in San Diego. Not good. Bob |

I deal with fire safety every day, I'm a fire protection engineer. You'd be surprised what fire can and cannot do. I always keep a small extinguisher with me whenever doing any flying, and would encourage everybody else to do the same. I've seen so many clubs that don't fly with some sort of fire suppression and I'd hate to think what happens if/when a small fire does happen. a $50 extinguisher is a lot cheaper than jail time, property damage or lives lost.
Just my nickel's worth....

D11-9
On a related topic, whatever happened to the Estes D11-9. It was great in my Skybolt and other lightweight D-powered rockets. Why did they discontinue it and when?

Strongly agreed!! The D11-9's were one of my favorites back in those days (loved them on my Goblin). The extra long nine second delay always gave those size models an impressive flight profile. They still make the D11-P's, and I may very well find some use for them (that's a topic in another thread I've posted....).

The D11-9 was a good motor for the Skybolt and the Cherokee-D.
Th only downfall was they were less total impulse than the D12 series in order to fit that 9 second delay in the same casing. I think those are nominally around 15 n-sec whereas the D12 is around 17-18 n-sec. The D11-P supposedly is the only full 20 n-sec D that Estes produces....my understanding is that it contains more propellant than any of the D12's. Why Estes does not fill the D12-0 almost to the top with propellant and make it a full 20 n-sec booster engine is beyond me. What happened to the D11-9 is like all the other discontinued Estes motors....no warning, it just disappeared from the lineup. That one actually had one of the shortest production runs (lasted less than 5 years) of any Estes motors but the B8-7 and B8-0; the B8-5 lasted for MANY years, but the B8-7 and B8-0 were produced only one year which was the same year that saw introduction of the B8-5 and D11-9 at Estes as well as the B8-3 with a Centuri label. This same year saw the discontinuation of all B14 motors from the Estes and Centuri lines. Why the B8-3 was only produced with a Centuri label and not an Estes one is a mystery as well. The C5-0 was never produced with an Estes label either, even though it was produced exclusively on Estes machinery. The only 18mm commonly produced booster engine that was any better than a C5-0 was the B14-0 (although the Cox D8-0 was arguably better than both, but was produced in much smaller quantities and only until about 1978) For a real screamin flight clone a 3-stage Astron Farside and fly it full-stack C5-0 to C5-0 to C6-7 and try to recover it from well over 3000'. A D8-0 to D8-0 to D8-3 (the 3 sec delay was the only ejection charged Cox D) would go to almost 4000' in that rocket.

I still have 18 or so C5-0 engines that I use for high altitude staged flights. I certainly wish Estes would make them again. Much better than the C6-0.

The average American consumer thinks that a bigger number is a more powerful motor, so they bought the D11-9 and pu it in their Maxi V-2 because they "knew" the 9 was more powerful than the 3 in a D12-3, so their rocket would fly higher. After enough crashes, someone decided to stop selling the crash generators.
