Perhaps we have gone a bit OT with this. The discussion was very useful I think, but I think the intent of starting this thread was more of a who's going, projects, what is this event, photos/videos, who had a good time, etc.
But, thank you for posting your experience Plugger. No wonder you have so many "likes." I've seen some damage on my rockets in the area you are describing and I thought is was landing damage. Now, I'm re-thinking that. Cylinders have a shape that can be very strong, but what happens when the airframe goes even slightly off-axis (roll and cone) and the angle of attack changes. Particularly during heating. Anyway, good stuff!
For tilt protection during staging, I'm planning on programming my rockets during testing (as a single stage rocket) just like it's a sustainer with the air start. But, timed so the ignition would be sub-optimal. The igniter will be a dummy load. Then, I will see, did it fire or not?
I'm looking forward to the class 3 experience topic coming up again. Maybe continuing when the summary is posted. Personally, I always like to define some kind of objective to judge the progress on any kind of rocketry endeavor. So, how about, to increase the annual percentage of Class 3 successes?
