I’ve got at least one and possibly 2 RRC2X altimeters I’d be willing to part with for an appropriate deal.Warren

I agree with you Adrian. I’m waiting for them to come up with certification standards for altimeters – when they do, I’m putting money down that yours returns more accurate altitudes.Warren

Word is TRA records committee will not be accepting any altitude records over 25K without GPS including the full raw stream data capture. Baro or Accel derieved altitudes will not be accepted.Warren

Now Doctor J, we should discuss. What I really want is an N1100. I bought (and still have) an M795 for my L3 cert, but ended up flying an AT load because I wanted to keep the altitude down. What…   Read more»

#1 – typically folks use 4F Black Powder, the stuff they use for flintlock priming pans.#2 – Yes, but a limited number of stores stock 4F. It’s a lot easier to find 3F and 2F and Pyrodex.#3 – I use…   Read more»

Join the club Mike. My sympathies. That prairie has eaten a number of my rockets. Occasionally it gives back the dead, but usually gone without a trace… RIP.WPS: There are still 3 of my altimeters out there on the prairie,…   Read more»

Yes, I’ve personally felt that Total Impulse is a better contest than AP weight. Jeremiah and I will meet later this week to discuss.Warren

Jeremiah and I have been talking about this for over a year. It will involve changes in the launch logs and launch log cards we use as well as some substantive database changes on our site. On the other hand,…   Read more»

As I understand it, thrustcurve.org supports remote queries. Might be interesting to look at the idea of dumping our database completely and using the thrustcurve database. All we need to mine from it are the motor code, manufacturer, total impluse,…   Read more»

Unfortunately, the old code from the website I took over computes AP bonfire by total propellant weight and not by type of propellant. BP is also added in. We are working on a fix to this as manually tabulating the…   Read more»

True James – didn’t even notice that. I’m waiting until Deb sends me the card. Sent everything off on Monday after O’fest. Should have it in a week or so.Warren

I’ll look into it, but I’ve never heard of PhpBB doing that (PhpBB is the forum module here within the site). As the forum software has to be adapted to PhpNuke, the site content manager, it’s not as simple as…   Read more»

It worked fantastic for me. (DC20 in my case). The button was pushed and we were back to the pad within 30 minutes. If Chris had driven faster, we might have been able to do it within 10 or 15…   Read more»

I probably shouldn’t be lazy and should go search for the old thread about Mike’s travails with on-pad deployment, but I seem to recall it was a completely different, home brew transmitter IN the e-bay with the altimeters that caused…   Read more»

Absolutely a pleasure to meet Dr. J and for him to come out and spend 3 days hanging out with us. Cesaroni definitely supports this hobby.Warren

My wife, Lea, and I discussed doing food at O’fest (she has cooked for the annual meeting for the last 2 years) but we didn’t want to step on anyone else and Kandy had come twice before so we just…   Read more»

Fin flutter is a real interesting problem. If you’d like, come by my EZ-Up (probably next to the admin EZ-Up on the flight line) and I’ll show you some fins meant to handle Mach 2 or better.Warren

There are a LOT of variables to that question – first two would be the size and shape of the fins. The larger the semi-span, the more prone to fracture due to flexing. Conversely, the shorter the semi-span, the more…   Read more»

Tim,I just want to remind you I need to borrow the AT 98/7680 case for that M1419 reload you sold me. I’m planning on flying Friday afternoon.Warren
