Con,And I have seen as many FWFG tubes shred at Mach 2+ as you mention surviving it–may be the vendor involved, wind shear, etc. who knows, certainly there are many variables. FWFG tubing is a great convenience and certainly more…   Read more»

Obviously just using composites is not enuf–I don’t know the details of Jim’s earlier attempts but my guess is that they began with FWFG tubing, a material many naively believe to be Mach 2+ capable. In fact I have heard…   Read more»

As I know about the flights at LDRS including the L3 cert (BTW to mention that guy that certed has tried several times before with a Minimum diameter N only to shred it a few of those times. Yes it…   Read more»

It’s hard to squeeze out a few extra hundred feet out of rockets. It takes the right launch site, weather, building techniques, motor and rocket to break an existing record. Precisely. Right now I have two boosts that have exceeded…   Read more»

Glad to have you here tony. Welcome aboard. Yes I know of the Q project you speak. The 100K+ flight I speak of was the OuR project. It was a full R motor. It was done by Paul Robinson, Ken…   Read more»

I’m new here…and have caught the end of this thread. One thing about altitude junkies is that they are not shy about showing you what they’ve come up with. It’s hard to squeeze out a few extra hundred feet out…   Read more»

No restrictions, Conway!

hmm. a free beer huh. I think I will just have to take you up on that JW… Does it matter engine or size of vehicle?

FWIW, I tried three times to break 20K before I finally succeeded. They were all really well thought out shots, or at least I thought they were. The rockets all cost several hundred $, and the motors were $250 and…   Read more»

I’m with Chris on this one, we,ve been flying sounding rockets way high since the 50’s. This is old technology and most of the info needed is in the public domain. most are staged. Its not the easiest, just more…   Read more»

let me clarify: when I said 35 to 40 taking no special talent–a min diam N will do it easily. Course the rocket has to be built with composite materials, and GPS or good beacon on board. Care has to…   Read more»

And if anyone from NCR could ever do it JW it would be you!!! I have the highest respect for doing High altitudes and doing good clean recovery. To me means nothing if I dont get it back. Anything over…   Read more»

100K? At this juncture, with our collective budgets (squared), I don’t think we could do it. Finding a waiver would also be a bit of a challenge. My suggestion is to try to get to 50K first, which is no…   Read more»

But be truthful. If your really gonna go for 100K think you will skimp and go cheap with the possibillity of not making it? nahh. I wouldnt. Let go for broke!!!

Oh – I agree. A 2 stager could possibly do it with a smaller rocket and less propellant though, and therefore be less expensive. That’s why I suggested it as an option.

Why do it on a couple of staged and/or P motors when 1 single R motor will do more then 100K. Its allready very tough to try and do. Just simplify a lil. To many things can go wrong in…   Read more»

Two stage max.

All carbon fiber, minimum diameter… how many hundred pounds of propellant? Now we’re talkin’! 😀

Alternatively, the right staged contraption and a pair of P’s could probably do it…
