"Starting State" Woes
I booted RockSim 9 today for the first time in a long while, and couldn't figure out why I was getting such poor flight simulation results.
After consulting the "Starting State" tab, I noticed the Launch Guide Length was 1200 inches, and the launch angle was 56 degrees from vertical (instead of from horizontal). It should have been 34 degrees.
--I suppose I should change those numbers to 36 inches and zero degrees from vertical.
I mean, we launched the "Evel Spirit" successfully, even if I *didn't* manage to make RockSim Pro match our test launch and actual launch results...
Sorry, I don't have any pictures of the "Spirit" descending under the fully deployed main chute, just these with the drogue chute pictured.
