So I used the blue - wasn't until much later when I finally saw one in a catalog, that I realised it was orange , personally, I still like the blue.

It's a unique color scheme, that's why I like it.

However, on the second flight the Rocket Gods were appeased. I think it's somewhere in Europe now....

That's really cool! I wouldn't have guessed that was an FSI EOS because of the clipped fins but it has a sleek look built like that. At first glance it looks like an Echo-1 for the booster but that would be too small of a diameter compared to the EOS. Did you custom make the booster? Must have been an awesome flight. I loved those FSI F7 and F100 motors.

Oooohhhhh yyyyeeeeeeeeaaaaaahhhhhhhh!

The Dart with the thruster system was awesome. Would really scoot off the pad. Any launch shot was a good one. I had my father-in-law video taping mine when I first launched it. Thought the booster had blown up. Always seemed to have a problem with the FSI motors CATOing. But, when I recovered the booster intact, I assumed I had broken the sound barrier. Circa 1987. Wish I had bought more of the thrusters.......(booster was just the FSI motor with fins glued on and a coupler to fit into the sustainer BT).

Yeah, there's something about a black powder F that composites just can't touch. Fire- Smoke- occasional catos..... It's life on the edge!
