Lots of flights, but appeared to have an overabundance of parachute deployment failures.

Hi, GH,
Yeah, three of the day's failures were mine. I've been plagued with that issue a lot recently.
I need to go back and assess my chute packing methods and correct this mess!

I think the main issue with the Citation Patriot flight was that I had partially prepped the bird about a month ago for a flight that never took place. I think I forgot that I already had wadding in the tube and, without checking first, stuffed more in for the Dec. 2nd flight. It was too much for the ejection charge to cough out.

Live and learn from dorky mistakes!

Nice launch! Y'all even had a mini FPOD (Flying Pyramid of Death). You had to be at LDRS XV to appreciate that one, right Earl?

Yeah, the pyramids were popular there for a while. Was that an M sparky motor flight at XV? Pretty decent sized one as I recall. Wow, what is that now, 25 years ago?? Hard to believe....

Yep, it was a big ole M to the best of my memory. It flew vertical about 30 ft and horizontal about 500 ft. IIRC, they were out of Florida. Nice guys. I was lucky to be working the range at the time so I got to see it fly up close and personal.

Twenty five! The mid to late 90's was my peak on HPR. The BATFE started making things miserable and we started having to buy AP by the drum from China. (IIRC the Pepcon explosion was late 80's) It became obvious to me that a hobby shouldn't make you go broke. I came back to LPR and haven't missed the big stuff a bit.

You can fly L1 HPR without breaking the bank, but not much more.
I just don't see any thrill in burning up multiple $100 bills per flight either.

I was doing L3 size EX. L and M motors and heading toward an N, 1/2 scale Aerobees over 12 ft tall, etc. Because it was EX, it was waaaaaaaay cheaper than commercial, but it was still expensive to drive to places with waivers, stay in hotels, take time off work, etc.

As for L1, I don't get any more of a thrill from a baby H than a triple cluster of C5's or C6's.

The price of commercial motors in any size in this hobby I find to be an outrageous ripoff with a captive audience.

Per flight time cost, R/C aircraft flying is far more economical be it glow, electric, or turbine.

Rocketry is more of a niche hobby than R/C. It's always going to be more expensive in comparison. But yeah, I think the 76mm L1000 that I flew at LDRS XV had about $25 worth of chemicals in the propellant (mid 90's cost) even with the titanium chunks for sparks. I think the 76mm M3000's we made had about $35 worth of chems. The stick of graphite for the nozzle and the aluminum slug to make the bulkhead each cost more than all the rest of the motor components and chems combined, iirc. At the bulk rates the commercial manufacturers were paying, they would probably have had less than $10 invested in the chems. Of course they had to pay for labor on the lathes and mixing chems where we were doing it for fun.
