why e744? what formula are you going to start with?

Thanks James.Yes, I do need AP, R45, although I was going to go with E744 curative. I’m working with Matt B. who I know has been in touch with you. Incidentally, I’m the guy that was bugging you to call…   Read more»

I have used AMW, ProX and some customer made ones. As Tony said, the trick is paper. If you want off the shelf look at AMW and Loki. AT has Everything you need as well but you will have to…   Read more»

So Tony, you have not developed a favorite, you just do “whatever works” is what I am hearing.As to wall thickness, I think its pretty substantial. Loki is apparently (in 54mm) 0.095, versus Aerotech might be as little as 0.058?…   Read more»

The trick is finding liners and casting tubes. I’m not sure if you have an ooops in Ex..that a case with .005 more wall thickness is going to help.Were’s the easiest place for you to get liners and casting tubes…   Read more»

I have mostly AT hardware on hand right now, just starting out in EX. Somewhat worried about ruining casings during early static tests. I guess I am looking for a flight-worthy alternative that costs quite a bit less and maybe…   Read more»

I use AT, Kosdon, CTI and stuff I make. It can all be used for Ex.What hardware do you use now?Tony

Can’t add anything to what Bear says and I’m certainly no expert, but have an example of how ‘not simple’ it can get. I built a little Estes kit with ‘enhancements’ – shock cord upgrade, reinforced payload bay, etc. Without…   Read more»

I read an interesting article about the lack of total success with the Falcon 9 launch. You can read it here//www.theregister.co.uk/2012/10/09/falcon_9_flameout_leaves_sat_low/

FYI, CATO is not an acronym for anything. There’s a nut over on TRF who just goes ballistic on anyone trying to use it as such. It’s just a shortened version of catastrophic failure (which could be at any time…   Read more»

I used the word CATO here simply to mean that an engine appeared to have exploded. In our hobby, of course, an engine explosion pretty much always results in destruction of the rocket. (as an aside, I’ve seen some hobby…   Read more»

I have some confusion about the useage of the term CATO. I am under the impression that CATO means something like Catastrophe At Take-Off. If that is correct, and it was over a minute into it’s flight, then it would…   Read more»
