This sounds like a lot of fun. Time to start building - I have a lot of ideas to try 😀

My dad will have his endeavour converted for dd by then - it's 6.5lbs right now - probably more like 7 after the dd conversion. He could definitely fly that. What does the most recent data on the J sh...

For dual deploy, I would go with a Rocket Rage RRQS15 as a main. It's rated for 15lbs, so it'll come in soft, but that's my preference for dual. For single, a 54"-72" parachute would be great (it'll f...

If that's the case, I have a design for a 14 motor monster 😀 Sure, it'll cost an arm and a leg, but hey...

I'm still waiting for my (backordered, of course) components to come in (especially some fabric)... I'll fly before Oktoberfest though. No November flight for me this year 🙄

I'll bring some 29mm cases. I think I only have one of that one, but I might have 2. (I'll definitely have at least one though). I also have the 29/360 😉 😆 😯

The year expiration states that if you let your membership lapse for more than a year, your cert vanishes. Other than that, it is permanent.

Here's a more detailed thrust curve:

True - I was thinking about the I405 nozzle when I wrote that. It's a hair smaller than the nozzle on the AT H268 IIRC.

Just was looking at the aerotech site, and there is an announcement there of the introduction of the J825 redline for the 38/1080 case 😀 😯 8) That should be a REALLY fun load 😀

1800psi? Wow... The cases are pretty thick though, and the I nozzle is pretty small, so I definitely believe it. They are very noticeable motors, that's for sure 🙂

Actually, the 38's if anything are cheaper than AT and CTI comparable loads. They are definitely nice motors - I've got all the 38 casings if anyone wants to try them. Hardware is a hair more expensiv...

Chris, just how much hotter has it to be? Ignoring humidity, can you do a 3-D plot? impulse on the z axis, AGL on the x, and T on the Y. Of course insoluble in closed eqn, only curious if you can get ...

Just remember guys, air density does not fall off in a linear fashion with increasing altitude. The roughly 3000 of difference between the north site and Hartsel causes a much greater fall-off in atmo...

Honestly, the only time you ever have to worry about overstability is when you fly a rocket on a motor that can barely lift it in high winds. Unless you're doing that, more than 1 or 2 calibers is jus...
