Thanks for getting it started. I sent out the site today. I plan on being there and even entering SSSS.Doug

Thanks Warren, I’ll hold off writing them until its up.Doug

BTW, darts are NOT allowed by TRA for altitude attempts. Don’t know why, but they are specifically precluded from the record books.

Makes sense to me. Its a rocket altitude record not a dart altitude record.

I have orderd directly from L L Electronics and you can save a few bucks. Also I specified the 219 MHz band since that’s the receiver I had and they had not problem building what I need. Here is their…   Read more»

No problem after the flight. Warren, for some reason I cannot find these pages anywhere except when you posted the link from the previous SSSS thread.Single Shot Sweepstakes rules http://www.ncrocketry.org/modules.php?name=Content&pa=showpage&pid=5Super Single Shot Sweepstakes Rules…[Read more]

Warren, I still have a few questions about the SSSS. Procedurally is there anything different about checking in with the RSO? In particular, will I have to remove the motor prior to flying? What about the electronics? I would have…   Read more»

I agree about the switches Jim sells. They are highly reliable and have minimum protusion ouside the rocket. Here is the link http://www.missileworks.com/Merchant2/merchant.mv?Screen=PROD&Store_Code=MWC&Product_Code=MWC-SW-2&Category_Code=cat103020He also sells them in 5 and 10 packs with some savings.Doug

please tell me you masked those rail guides before painting! I can’t tell from the photo’s.Doug

I’ve pulled it into Excel, but the baro data is really noisy for pulling derivatives for velocity and accel. Anyone got a spreadsheet with some good smoothing or curve-fitting algorithms in it?Excel does curve fitting. After you plot your raw…   Read more»

Warren,For those of us not at the annual meeting, do you have more info about your project? Do you have a web page?Doug

It’s really not hard but it does depend what it is you want to vacuum bag. I don’t know what technique Conway is referring to but I would be happy to help you out with the vacuum bagging if you…   Read more»

how is this current arrangement stacked against you (or any of us?)Since the gist of the single shot contest is that you only have one attempt, then why provide the opportunity to make that attempt last the entire year? It…   Read more»

I personally like everyone using the same motor.As far as getting several guys to flyin the same day… to date, we haven’t been able to get five guys to fly in the same *season*Although I would probably prefer a greater…   Read more»

There is the basic rules posted under contests but not the details. I guess I could compete but there is a big difference if you local guys could pick and choose any month for the perfect conditions to fly in…   Read more»

You can enter until the first shot goes up.Ends at the end of the year, prize will be awarded… at the annual meeting

That eliminates me from competing…Doug

Could I get some clarification on the rules for SSSS. The site states- Highest altitude on a J350 motor.- One shot, one try.- Electronic tracking allowed.What is the entry fee?What is the prize?When does it run? (All year?, once per…   Read more»

I would go with option 1 because you should have more than enough oomph to worry about weight. The H242 is a pretty kick butt motor and should get you cert 1. Build strong and go with option 1. Good…   Read more»

It sort of depends on how long the runs are but I have used about 1/4″ ID tube for 30″ long runs for a single e-match wires with no problems. I would think for short runs (I guessing you have…   Read more»

Ken,Since you are still doing construction, I recommend running small tubes from the forward compartment to the aft of the motors. There are several different ways to airstart motors but if you have a tube to pass ignitors through, it…   Read more»

we found a way to deal with that without me having to deal with them.

OK, I’ll play. What’s the deal?
