As someone who used to mess with Estes model rockets, I felt the need to share this cool video I stumbled onto on Youtube today:




And it takes off so FAST.

I get a nostalgic smile when we drive through Huntsville and see the rockets. <sigh> Those were the days of big dreams.

Thanks for that video. Something I've always wanted to do, but haven't.

Default That was pretty cool...

- but in threads about amateur rocketry, I am obliged to link to my stark-raving bonkers countrymen who are going all-in on this rocketry thing:


HEAT-1X launch Copenhagen Suborbitals - YouTube

Doesn't look that impressive without scale, but that orange bit at the top holds a full-scale crash test dummy. And the rocket engine is a home-made hybrid, paraffin/LOX. Went supersonic, even. The veered off course and had to be shutdown, but... Not bad for a couple of guys working on donations, hope and ingenuity.

They hoped that movable fins with rollerons would do the trick, but no joy. Currently, they're working on movable vanes in the rocket exhaust, V2-style. And, because they thought it might be fun, they're now delving into liquid-fueled engines.

Looks pretty cool. I got to see the last Saturn V rocket two years ago when I was in Houston.

But it'd didn't seem like it went up that high. Perhaps the size is misleading though.

Saturn V is absolutely huge, it's longer than a football field.
