So the reason that these wind considerations are so important is that central Missouri tends to have a lot of trees and I have to deal with somewhat constrained launch areas.
It is somewhat of an art to be able to gauge wind speed and direction to figure out launch rod angle to get rockets to drift right back to your feet.
And as we know in colder temperatures under 50F, plastic parachutes tend to get stiff and refuse to open -- the immortal "plastic wad" recovery system.
Sucks to bust off a fin on the Astro-1, but replacing balsa fins is usually not a major operation. As long as the fin root itself isn't torn off the body tube, should be a fairly easy fix.
thanks for the comments...and I actually oriented those fins wrong on the Astro 1. I had the balsa grain parallel to the body tube. I learned from some great input from this site, by Rex R and K'Tesh, that I need to pay more attention to the grains on those balsa fins -- that is, having the grain parallel to the leading edge.
This site is the greatest!
