An eventual goal would be to create a landing map based on altitude. That way we could identify trends that would allow us to be better able to make the call about when to fly to higher altitudes and ...

Over the years flying at the North Site I've had the privilege to roam and learn a lot about the prairie. I've also had some great recovery trips with good friends that I wouldn't trade for anything....

What about epoxying in a piece of all thread, 5/16", and stacking washers on this. Then you can tailor your nose weight to what you need, and be able to have a way to do tracking in the future. You w...

I have ten (10) 96" Toroidal Parachutes that I'm selling. I had a contract to make them for a local company and then their contract got cancelled. These chutes are not yet made, but I have them all cu...

Jack, If you'd like to talk over altimeters, e-bay, etc and see some of my designs in person I'd be happy to help you! Edward

Very nice! How is the condition of the pipe stubs in the concrete. I see the tee fitting I put on them a while back is still there. I think I also put a coupler on one to help keep them in shape. P...

You'll get a rocket that has some nice coning action. I had a rocket like that once also. Fin was leaning. About 5 seconds into a 8 second burn the rocket was coning in about 5 foot diameter circle...

When I flew I had everything shielded, and wrapped the ejection charge wires in aluminum foil. I would do this before you drop the altimeter - backups are good to have. Edward

Did you have your electronics shielded? Edward

Maybe it would be good to contact the membership via the NCR e-mail to let them know of the changes to MHM and solicit input. Seems like these forums are pretty slow. Edward

With NSL over MHM weekend it seems very unlikely to me to be able to have our launch that weekend. It would split the participants and vendors. Would it be possible to schedule MHM 2013 For May 31 th...

So this year between the launch site conditions and then the weather this weekend, we'd have never had a successful launch. I was looking over my rocket schedule for next year and noticed that Oktobe...

Nitrous doesn't have a shelf life that I know of. I generally go through about 150# in a year so it doesn't sit around long. I have had a 20# tank sit around for 6-9 months. Still works fine as lon...

I have extra o-rings that will fit 54mm and 75mm - let me know and I can get them to you before your flight. Usually white crystals appear on the surface of the propellant. You sand that off and you ...

Most propellants will swell slightly and pick up moisture. Replacing the o-rings is just cheap insurance against them swelling or becoming deformed during storage - especially if the grease used is n...
