- Something that I didn't see in the FAQ was tips on tracking a medium to high
- power rocket once it flies out of visual range. I _had_ a rocket that soared
- very nicely up to around 3200ft. It was a windy day, so I put a siren in the
- rocket and launched it about 70 degrees from the horizon into the wind. I saw
- the chute open :) and proceeded to make a BIG mistake: look down as I walked
- towards it. I could have kept track of it if I hadn't taken my eyes off it, so
- it was history :( . I spent a couple of hours looking for it. The siren is
- probably only audible if you're close enough to see it.
-
- The question is, is there some type of smoke or colored chalk dust you can
- use to make the rocket more visible as it comes down? If so what type of
- mechanism (commercial or home-made) do you use to steadily release the smoke or
- chalk? And what other methods could be used? This is the main issue keeping me
- from tackling high-power rocketry where I plan on breaking 3200 ft.
-
- BTW, does anyone know the decent rate of a 1lb rocket with an 18" chute? I
- guessed that it took about 90 seconds for the rocket to land with the chute.
- With about a 25 mph wind that puts the rocket at (25mph * (90s/(3600 sec/hr)))
- .625 mi from where I launched it. So that was where I concentrated the search.
-
- Thanks in advance for any help :)
