The rocket at the end is a small hobby project I’ve been tinkering with off and on in my copious amounts of free time (sarcasm) over the past few months. It’s called “Hummingbird”, mostly because it is underpowered and small. It’s powered by a G motor, so it’s not even high-power, I just wanted to do something small. It’s small enough that it won’t break the bank developing it, and the motor reloads are super cheap. I don’t know how well the exhaust vanes will work. I’m already planning the next version. Anyway, hopefully some time soon I will have some time to make a post or a web page about it. I haven’t worked on it in a while but it’s coming along.

I don’t think I’ve seen Aerolab or RASAero before, thanks for the links. I will have to take a look at them when I get some time. My main issue was that I could design something and simulate it, but a few small goofs and my numbers could be completely unrealistic. I eventually learned that the ARTS 2 altimeter actually comes with software that allows you to back out the drag properties from flying an actual vehicle — I like that idea because it’s almost like having a wind tunnel that you can test your full-size (or mockup) vehicles in. If I’d known that the ARTS had that feature built-in I wouldn’t have bothered putting my simulator together, although I did learn from it.

Cool stuff on your website, I’ll have to look through the rest of those reports. It’s nice to come across a like-minded person.

What was that project mentioned at the end of the video? Is there a link or additional information about it?

Also, regarding an earlier post, are you familiar with Aerolab (http://www.dark.dk/) [see downloads] and RASAero (http://www.rasaero.com/) for drag estimation?
