Forsyth, Missouri.

I also saw a better one pop on Facebook a couple weeks back.

I don't care how much this costs. I need this as my school bus

I binge read 'Saturn Run'! My friend gifted the ebook and said he will be getting me a lot of space books, like Stephen Baxter's Manifold series and  NASA trilogy :D.... I feel bad that he has to spend money though... but he doesn't mind, so I guess its OK...

So today, we're starting rockets in physics. Easy. Freaking. Peasy. I go onto the design program we're using, make a basic PVC body, cardboard fins, and 3D printed nosecone with the provided engine, and go crazy. After tweaking, I managed to create a monster.

835m Apogee

177m/s max velocity

But then, I ran into a problem. The motor we're using has a set charge time. We can't change parachute launch stats. *sigh*

New stats:

644m Apogee

171m/s max velocity

Errors: Chute is deploying at 47.8m/s.

The apogee on the Raptor I is a stunning 2,112.9 feet. I think we might have to call the FAA. And get more durable chutes.

OpenRocket, by any chance?

And what class is your motor?

Must be a pretty light rocket to get up so high. The rocket I flew had a J motor and had an apogee of 1029 m (OpenRocket predicted about 1200 m). It had a big avionics bay, though, and the body wasn't incredibly light.

For our parachutes, we used an altimeter to set off our own charges at apogee and then at 500 ft. This is pretty common for high power rockets.

Last night I finally ran my computer hard enough to make my UPS beep about overloading it.  Nothing shut off, I think it was just the "If I lose power, I can't hold this load" beep.  Still annoying, though.

I managed to go a whole two and a half weeks without ordering anything from NewEgg, too.  Oh well.
