I'd love to find long-burning, full-impulse, G, H, and I motors. I didn't see anything like that on Loki's website, though.

In the muck at the edge of the new lake SW of the windmill I found and recovered the back end of a black and red rocket, about 3" diameter, with triangular fins. The nosecone is still in the muck. I...

It's East of the launch pad (Way East), and has a fluorescent pink parachute and a Parrot altimeter. From the way it was arc-ing over on an F10 (8 second burn) I'm guessing it's at or beyond the wind...

Actually, the no tracking rule was designed to ADD participation. It was an attempt to level the playing field and bring more folks in. There are a lot of flyers w/o tracking and they wouldn't / could...

Adrian, I totally understand your issues. ... It is tricky indeed. Thanks, John. I'm still keeping my eye out for your G. And thanks for Fudd ignitor, Ken. I think I have enough data now to pull the ...

You can borrow my tracking setup if you want. It's an Arrow 5-element yagi and a scanner. I'm still shooting for having the first batch of Parrot altimeters done and certified, along with record atte...

I'd love to do the SSS, but I'm stymied by the no-tracker requirement. Today I just lost a 38mm rocket (Blue Ninja) on an F, in almost zero wind, despite a day-glow pink parachute, because I didn't f...

I love this. A Nikon Coolpix "launched" to the edge of space from what is clearly someone's back yard. [/url]

Does anyone know what is the range used in the commercially available units? The chips can range from 1.xg to well over 50g per axis. I'm tempted to settle on the +/-18G per axis, knowing that a small...

Radar estimates show that the North site got well over an inch of rain yesterday. Nearby locations got over 4". That should help green things up for the September launch.

Thanks for the link. The wind velocity was so low, though, that I'm not sure how relevant it is for F or G records. Maybe if they had used much larger models to get a better match with the Reynold's...

It would be interesting to swap back and forth on a High perf supersonic bird to see what gives. Yeah, Chris got some good data on his Cd as a function of velocity. It would be really interesting to ...

When I recovered, I found it was not even on the same page as the sim... Yes, the date would be particularly interesting. Maybe you were using an older version of Rocksim at the time that didn't mod...

I don't want this to come out wrong and I don't want this to come out smarmy (that was a disclaimer) but simulating something and flying it are two totally different animals. The TRA "F" record hasn't...

One way to think about it is terms of a work function. Work against gravity is constant depending only on the endpoints, while work on drag is not a state function, (in math speak, instead its a line ...
