I just downloaded OpenRocket, which is an open source rocket design and simulation software. So far I love it much better than RockSim, and it is absolutely free. RockSim has some quirks that are very annoying. While OpenRocket is somewhat less glossy and perty than RockSim, it does the job well and I believe it is more user-friendly and powerful.
Get it here!

Build Pictures for the 2-Stager!
I have made TONS of progress on my recent project since my last post. The exterior of the sustainer stage is finished, and the inside of the booster stage is finished. I have yet to put in the altimeter bay, recovery system and staging electronics housing on the sustainer, and still need to glass the booster airframe and paint it.
My work on the booster is rather unconventional. I cut out some strips of 1/4 inch plywood and glued them between the fore and aft centering rings. I then wrapped around the entire booster with plastic wrap and filled 'er up with expanding A-B foam epoxy.
I took this rocket to the county fair (it's my last year in 4H), and it got a purple ribbon. So I will be taking it to the MN State Fair this September, which means I will have to come up from college that weekend. I have a good reason to do so, however: If I participate in the State Fair this year, I am eligible to apply for a scholarship, so it is worth it.

Complex L2
You better believe it. It's time to bring out the big guns. I ordered some supplies from Public Missiles last week, and today a big box was waiting for me on the dinner table when I got home from work. Inside were two 4" body tubes, three coupler tubes, and a nose cone.
I am planning to build a two stage level-2 high-power rocket. This will be the biggest project I have ever undertaken.
I also plan to use the sustainer stage to certify L2 this August.

New Workshop Build Pictures
Oo looky here! Is Daniel about to build something? It sure looks like it. But what?
Hm. What is this?
Aha, it's starting to look like...
A workbench!
My new, cozy little workshop:

A New Workshop!!
My dad has given me permission to use a corner of the former horse shed as a rocket workshop! This could be a great investment of my spare time for future projects. It is also a great place to store my rockets, especially as they grow in size.
So far all I have managed to do is clean out a spot and put in an extension cord and power strip. But I have plans to build a workbench, a stool, and a fancy rocket stand!
Stay tuned for more details as my ideas take shape.
Also, I have a new project in the works... it involves level-2 motors. Emphasis on the S in "motors."

Fail. Again.
I was able to get off work for this Saturday for this month's Tripoli MN high-power rocket launch. The plan was to try and certify level 2 again, since I failed my first attempt last month.
I'll cut right to the chase and tell you I failed once again.
I swore that my system was fool-proof. It was super simple: a large 10-lb rocket on a large sparky J-motor that would go to 2000' in altitude and land gently on the field under a 72-inch parachute. No dual deploy, no electronics, no rocket hunters, nothing fancy. Just the basics. What could possibly go wrong?
The parachute got stuck inside the rocket, that's what. It came out just fifty feet above the ground, giving us false hopes that the rocket would survive, and we thought it did. But a tent in front of my view blocked the fact that the rocket separated, and the rocket was rather damaged.
I'm not as disappointed as I could be, however. Because I can still continue to fly level-2, and with a 15% discount for certification attempts!
Here's the video:

Working
This summer is much less "fun" than other summers, because I have a more-than-full-time job working on a sod farm. I worked almost 60 hours last week! In the HEAT!
I have survived so far, but unfortunately my rocketry work hasn't. I have just one week before the next HPR launch to prepare my newest creation, which I hope to certify level 2 on. Photos will be posted soon.
This is rather important, however. I need to pay for school!
Happy Independence Day!
