I used AeroPoxy a year ago on my minimum diameter “M” shot, and I used heat lamps to cure it. AeroPoxy is wunnerful stuff. This year, I used ProLine epoxy, as I had heard it was a bit better under…   Read more»

You would Joe…. I like the glue sticks better myself, less of a mess….Mike, if you want to use some mylar let me know, I have a roll I picked up from Conway last summer.I bought Aero and wish I…   Read more»

I still prefer Elmer’s School Glue and wheat paste – tastes better and is less fattening.

Personally I’m a West Systems guy, but I do consider the Aeropoxy resin to be a superior product in terms of its characteristics. I use West largely because I have very long experience with it in boat building and like…   Read more»

I just finished off my gallon of Aeropoxy I bought 3 years ago. Works really nice – just wish it would cure a little faster. I fiberglassed at least 8 x 98mm x 34″ tubes. 4 x 64mm x 34″…   Read more»

Mike, I love the stuff. While I think it’s the best on the market (get it from Tim Thomas), others may say that West is best. I’ve built two rockets with a quart of the structural and laminating adhesives this…   Read more»

I used AeroPoxy on my M1450 boost. I used convolute wound glass, so all I had to do was the tip-2-tip stuff. I did 5 layers of that. A quart (of mixed product?) should go quite a long way. The…   Read more»

That is odd – I can’t think of any possible causes. I’ve been slacking on getting the most recent version rolled to production – we’re still on a pretty old version of the forums code. Perhaps I’ll be able to…   Read more»

Thanks, Warren. It seems odd that BOTH of my computers would succumb to this? I’d toss my cookies (so to speak) 8)

I dunno… I haven’t had the problem so I would suggest you clear your cookies – if you know what I mean. It’s a browser thing. Call me and I can walk you through it.Warren

I’ve had great luck with them, I really like the fact that I can use 10.5v batteries with them and I like the dip switches. Never a problem with mine, and I have pushed one of them to 70+ gees…   Read more»

I would consider this a “flaw” – yes it is purposefully done, but it is ridiculous. Better it should read out 99,999 feet instead of an altitude within it’s ostensible range. Jason Chamberlin turned in a 20K flight a while…   Read more»

Warren,I don’t think that’s a bug in the firmware, but instead a programmed error code.In any event – you are correct -it’s not an altitude it’s beeping out.Ed

Bummer if you beat the J record and it happens to land on 20,000 feet and 4800 samples.

By the way, I looked back at the data and confirmed that the AGL for John’s flight was 24,724 feet, when calculated in the traditional way based on the standard atmosphere.

OK, more questions from a non-engineer Shocked the blue line seems to be essentially peaking at just below 25K, with some bigger spikes. The 25,724′ would seem to be such a spike. Isn’t that an anomaly (“noise”?) and if you…   Read more»

I put in a small (2 or 5, I don’t remember which) degree initial flight angle, mostly because there was some measured drag acceleration at apogee. You can see from the Cd plot that the assumed Cd shoots way up…   Read more»

Adrian, I’m curious why the velocity never got to ~0mph. I understand if there is a parabolic trajectory it may not ever stop completely, but as you saw it was a *very* straight boost… I’d have thought it nearly did…   Read more»

does not sound like a problem to me, why not
