Well, I got to fly my cardstock rockets today - some successes and some "back to the drawing board" moments.
First problem was the digital camera - turns out we left the film card back at the house, so no pictures!
Flew the small Saturn V twice - flew perfectly both flights. Didn't check the altitude, but it got up high enough for me - and my Mom (I took Dad flying for Father's Day, and Mom tagged along to watch) really loved this one. A really sweet flyer.
I flew the small one I called the lemon drop - it is a 13mm powered featherweight about the size of a Mosquito - it flew twice as well, and performed as expected.
Then came the Prism - the rainbow colored rocket in the photo in the above post. The rocket flew well, but at ejection it blew out a side seam. It recovered ok, so it'll fly again with a minor repair. I may do a redesign with a stuffer tube though.
Finally, the Phoenix flew - that's the space fighter in the photo next to the Prism. Boost was good, but the chute tangled with the shock cord and never made it out of the tube - she hit hard and shredded the front part. After a careful examination, though, I think I can replace the front section and try again. I don't think this is a flawed design, just a recovery failure. I'll fix it and try again.
