If I’m free on that day, and I can do anything to help, I’m game.Looks like my SSS shot may be pushed back to oktoberfest, as the fireban continues…

I’ll also be working on another project this summer – no guarantees about it’s readiness for oktoberfest.Teaser specs:2 motors7 feet tall20lbs

Well, that is likely to be the next flight of my Black Brant X.It will go up on another 54/1706 load like it did at Mayhem (not sure which one though – possibly a long burn, or maybe redline). If…   Read more»

I think it’s a perdy thing too, but it’s not a rocket :)Take your pick from the following two:Massive Ordinance Air BlastMother Of All Bombs

The orange one ain’t a rocket – it’s a MOAB

Yeah – although it’s nowhere near as stiff as the carbon honeycomb :)Either material is great for fins – I doubt I’ll use G10 ever again.

I have to agree with john about the CF honeycomb. I have some 1/8″ thick, and it feels about as stiff as 1/8″ G10, but weighs less than 2oz/ft^2. Incredible stuff, and practically indestructible.

I prefer tempered (AKA spring) steel. Stiff, and the reason I like it is that if it does bend, it springs back easily (it doesn’t stay bent), so that overall, it maintains a straighter launch rod over time. If you…   Read more»

Not a problem. Actually, the implication was kind of funny to me – that you would imply that the $2 worth of materials was instead a high quality PML component worth a LOT more money I will change it around…   Read more»

Actually, I jerry-rigged the remove before flight pole with $2 of steel rod from lowes and $.80 worth of switches from radio shack Still, it is a decent alt bay, but all of them should have many of the same…   Read more»

Very nice altimeter choice :DI use one, and it hasn’t failed me yet. Very easy, very reliable. I can’t be there on June 10, but good luck with your altimeter adventures 8)

I’ll be down at hartsel for EX day, but I won’t be flying much. I’m saving up for LDRS 8)I can’t make the June 10 launch unfortunately – ACT

BP is easy – sulfur, charcoal, saltpeter.Some others are a little harder, but honestly, it’s amazing how easy it is to make many dangerous things. Nitroglycerine is a piece of cake, all you need is nitric and hydrochloric acids IIRC…   Read more»

OK, put my foot in my mouth there…What I meant to say was that for HPR, that was the only major differences. THe LPR contests the NAR holds however are definitely unique, and a great way to learn to build…   Read more»

There are really not that many differences. The major one is EX – tripoli L2 and above members can do experimental rocketry, while NAR has no procedures or regulations for EX. Other than that, the differences are trivial.

Not a problem – we don’t really care (Actually, standard is better in many ways for our purposes). I too will have an almost full 1lb can of 4F – if you need any, just ask.

Only if it is FFFFg (4F). 3F works too, but 4F is preferred. IIRC, flintlocks only use this for the tiny primer charge. If you have some, bring it though – great if you drop an ejection charge, or something…   Read more»

There’s a store called the blunderbuss, specializes in BP stuff. I can’t recall the exact location, hopefuly someone will remember. If you can’t find any by the launch, then lots of people up there should have it.

Again, like I posted on TRF, maybe try a gelcoat finish rather than straight epoxy? It’s designed as a finish layer, and as such should not bubble.

For that rocket, you should be fine. My dad uses the full charge (and no more) with his PML endeavour, and it works fine (4″ with no piston, loose fit).
