I am tempted to buy one just to support Gary's willingness to make such instrumentation available to experimenters.

I wonder if there is any software. I suppose the data sheet says.

I couldn't find it. Anyone? AnyOne?

Wondering how it compares to:

I wonder what the market will be now that all EX guys need a LEUP. And possibly a LEMP.

And why would 'you' think ALL EX guys need an LEUP?

HSA effectivly removed the instate loophole. Thats why the previously quiet ARSA suddenly became very vocal.

Of course you can still make motors under 62.5grams.

Then again I am not sure if it applies to raw AP, anyone know where to buy

62.5g batches of AP? ;-)

ONLY for non-exempt explosives.

It most certainly does not. In fact, more often than not it does not mean APCP.

What makes you think EX = APCP?

WRONG.

I can make as big a motor as I wish.

Do you see AP on the explosives list? I didn't think so. Maybe it's time to read up on the law.

In the UK it usually means Hybrids. Several groups building their own hybrids, including this lot...

Not directly, though I heard from a UK based member that everything was going well.

Bingo. EX is all encompassing, including water propulsion. ieas.org

Joel, Can you inlighten us as to how much EX work is done without APCP? I have just never seen the figures. And I don't mean hybrid or liquid. But composit motors. I know there are other oxidizers but I thought they were harder to work with. If not someone should tell NASA they figured it wrong. Oh and all the motor vendors too.

My name is not Joel. However I probably have a better overall feel.

  1. Sorbitol (ie sugar motors)
  2. APCP
  3. ANCP
  4. Zn-S
  5. KPCP
  6. Black Powder (but #1 in the pyrotechnic field).

You know, I don't know either. I'll go out on a limb and say not all EX'ers want to be counted. But then I'm not implying that "everyone" uses APCP (by stating the HSA killed EX). Actually, all "I" have to show is that a single EX'r plays with something besides APCP. Here's 2:

How do you back up your assertion that "all" EX is APCP?

Oh please. Harder than the mixture using the "common oxidizer" which has killed 'at least one' worker and completely destroyed a commercial facility?

NASA uses liquid oxidizers, what did they figure wrong? They have a very specific goal, and it's not the same as 'all' EX.

Just because NASA uses APCP in boosters, and motor manufactures use it for plugNshoot, "everyone" has to? Does everyone have to launch the type of rockets that NASA built and kit manufactures produce?

I hear your bridge calling you.

NOS/hybrids/ liquid/hypergolic fit in there somewhere as well. APCP is just a percent of EX/Amateur. Lets not forget H20 and steam either.

  1. LOX/Alcohol
  2. N2O/plastic
  3. LOX/HTPB
  4. H2O2
  5. steam
  6. water

remember "consumers" are excluded from this list or water and hybrids would be higher.
