Well organized event - hats off to the leaders who made this happen.
My flying was so-so.
I lawn darted one rocket because I had simmed with a 24mm F51 Classic but in my morning stupid stupor bought and flew with the much less powerful F51 Blue Streak. Delay of 7s was absurdly long for that motor, the motor ejection happened on the ground, and my hot wire cable cutter rig didn't get a chance to show its stuff. On the repair bench, but poor showing on my part.
Kevlar burned through on my rear eject rocket, fixable, some crumpling of the upper 2" of the body tube.
Coupe of nominal mod rocket flights - there were a lot of cool low and mid power rockets flying from those pads.
One acceptable flight of The Tick, my 4" x 63" upscale of the Fliskits Flea on a CTI K1440. (Flew it once before on a J760). Flight to 5386', 24" drogue at apogee, 60" main at 800'. Some L3 practice on this rocket - two fully redundant ejection systems both powered by the new compact Stratologgers, all charges fired when expected. Data shows drogue only at apogee, approximate descent rate of 70 fps, slowing to 20 fps once the main deployed, so shear pin configuration is good through two flights now. It's a big finned and heavy rocket, and it did (as far as I could tell) coast and arc over for too long after the short 1.7s burn of the K1440 - recovered safely but on the far side of the drainage ditch so had to drive around.
Left on Saturday after only 2 days of flying - weather! All in all very glad I went, some very impressive flights and equally impressive cato's!
(My son with some of his CMASS/MMMSC buddies - he had a great time as did all the kids!).
