The reason we disallowed tracking for this particular contest was that several folks indicated that they felt those of us who used tracking had an unfair advantage. (Disclaimer – Many of you know that I use tracking on 90%+ of…   Read more»

When we rolled over to the new website, we lost some stuff… one of the things we had SOMEWHERE on the old site — in the club charter or FAQ — was a notice that you could not claim a…   Read more»

Well you kicked John’s butt with that altitude… nIndeed he did… that said, as I noted in the forums earlier this year, I wasn’t going for shear altitude — I placed a lot of emphasis on recovery. I remember posting…   Read more»

Elvis has had his problems w/ HyperTEK, as have others. The stem issue has been a booger. I have heard TCO has had issues as well.Doug Pratt sells igniter grains for the RATTs, which are conveniently just a hair under…   Read more»

The RATT is more of a bitch to prep and light, but the Hypertek has more GSE to deal with.WarrenBoy, with all due respect, I have to totally disagree. We’ve had 100% success with lighting the RATT, except once when…   Read more»

We have had great luck w/ RATT and Sky Ripper. I’m very much looking forward to Edward’s system. It is very fair to say that we have had less luck w/ HyperTEKs. It is true that they have flown at…   Read more»

Tripoli rules preclude darts for single motor altitude events. My comment was more along the lines of the SSS rules, which don’t specifically preclude darts (IIRC). You are correct, TRA rules do rule out darts… But I don’t know that…   Read more»

I would guess that darts are OK? I don’t think the rules preclude them….

Warren, how much is in the respective SSS and SSSS kitties?

I, like many, have taken much for granted. We have a lot of excellent volunteers — Dale and Patty are right at the top of the list. Our prefect and prez does an incredible, tireless job as well……….

John with your H record you did at heartsal were you hitting mach 2 ? Nope… that was quite a blast, but IIRC the sims said something like 1200mph. That said, to my eye that boost looked faster than my…   Read more»

Kyle, I had the rocket you mentioned in my hands this week – your dad showed it to me. The work you did was FANTASTIC!!!!!!! and I mean that with all my heart. That said, it is my opinion that…   Read more»

The problem with a fit that is too loose is that the very wispy, thin parachute material could theoretically get pinched between the wall of the airframe and the piston — which could indeed cause it to jam. Too much…   Read more»

Never once have I had a piston jam. I’ve had ~200 High Powered flights, and off the cuff I’d say 90% of them had at least one piston and 80% of them had two pistons. I also fly almost exclusively…   Read more»

Pistons work ideal in filament wound glass tubing. The tubes are slick, don’t get dinged (which can cause a piston to hang up), etc. I use pistons whenever possible, and almost always in glass rockets. I’ve gone up to 5″,…   Read more»

….with my volume, so I’ll start with 2 grams and no chute.Bruce, I have found **PROFOUND** differences in ground testing w/ and w/o the chute! In other words, if 2g works w/o the chute, that doesn’t mean it will work…   Read more»

Thats interesting on the ematch differences there. Any Idea why? Has anyone used the quickburst ematches yet?The reason is because some of the ematches have differing amounts of pyrogen. IIRC, the difference between a 28B and a 28BR is that…   Read more»

Doug, that is solid advice. The online calculators are a decent STARTING point, but that is it. I’d never dream of flying a bird w/o a ground test first — unless I had a very, very similar rocket that I…   Read more»

Also heard, or read in Canepa’s second book, that attaching (how? your choice) Blue Thunder propellant to the igniter helps get things hot enough quickly…I’ve seen guys put Blue Thunder shavings into the corner of a baggie, and then run…   Read more»

It is often advantageous to sand AMW grains to expose raw AP. IIRC this is in their instructions? When flying the old Kosdon loads, we always sanded with ~150 grit or a bit more coarse.I’ve never sanded AT grains, unless…   Read more»
