That is one of the BEST CATO pics ever! You can actually see the thrust ring in the debris cloud. Amazing shot.

Wow, I've never seen a black powder motor spewing out flaming chunks of propellant! Thought that was reserved for larger motors.

The motor was a 38mm CTI H225-14a. CTI replaced the casing, adapter and motor.

I made the mistake of using only engine deployment in this GPS radio test. I did not have enough time to install the new Raven3 and the ejection wiring. The 3.5 lb rocket flew sort of nice on a CCI G78-15 but the whole flight from start to finish was 15 seconds. The motor ejection blew .5 sec after "landing". The whole rocket went in just as you see. The Raven3 was still working and the GPS radio had a broken battery wire or it would have still been sending. The only loss was the battery, and the av bay case which had to be cut in half to remove the hardware. I really lucked out. Once the video is cut down I will post on YouTube. The camera survived also. The video shows the whole flight looking at the back of the rocket which was looking down at the beginning and up at the sky through the remainder of the flight. As the rocket hit earth you can see the ejection charge puff out the rear of the rocket .5 seconds later. If the front had not been buried it may have separated the rocket while stuck in the ground.

Several years ago, as I was first dabbling in dual deploy, someone recommended that I use a new, fancy battery holder rather than the caveman zipties I used... Well, umm, the new holder failed to hold the battery. No battery, no altimeter. No altimeter, no deployment...
