Made my L3 attempt yesterday, I say attempt because I'll never know if I pulled it off or not as the CTI M1400 decided to pop the rear closure at about 200 feet. While it was one of the most "exciting" flights of the day for most, it pretty much ruined my day.
Damage was done pretty much throughout the whole rocket. The pressure from the CATO took off everything aft of the middle centering ring and slammed the case into the e-bay which telescoped into the payload bay. The e-bay folded up like a cheap suit, but I may have been lucky enough to have been spared the two altimeters. Both will start up when powered, but I'll have to test them to be sure no damage was done that I can't see. When the e-bay was stuffed into the payload tube, the three stainless screws that held it in cut grooves about an inch or so long into the bottom of the tube before they got pulled out of the coupler. The coupler was wedged into the payload tube so hard I had to cut the tube to get it out. I lost about 8 inches of length off the tube. The nose cone has a pretty big ding in it, but is repairable. All the main recovery parts are undamaged, but the drogue chute is trashed. The drogue harness looks OK, just had two bent quick links. We recovered all three fins which were undamaged, the motor mount tube is intact (believe it or not) but the booster tube is in pieces. We also found the Aeropack, it has a fair amount of damage to the retainer ring, but may be able to be straightened. The (borrowed) Aeropack adapter is also bent, but that may be fixable too.
I'll have some pics, and maybe video later this week. I already have plans to rebuild the rocket, but it will fly on a LOKI motor next time. FWIW, this was the second CATO in a row with the same motor at our club. In fact, the case I used was a brand new warranty case from the last one. This was a 75mm CTI standard propellant motor, and I've been hearing about other CATO's with this motor, after the fact of course. It's bad enough that it ruined my rocket, but hey, it happens. I'm very upset that it ruined my L3 attempt. Now I have to spend all the time going through all the cert stuff again. So, just be careful with the CTI 75mm motors.
BTW Mark, All the stickers survived.
