2 Days before my first Dual Deployment Attempt, and I'm playing with Pyrodex Ejection charges (I'm 19, so I can't get BP. Curses...) and I made the discovery that containment helps it burn. So I decided to contain in CPVC pipe hot-glued in both ends...

Needless to say my brand new, never flown hot rod Buffalo DD Suffered 99 problems, and a breach was one.

Of course this is the attempt I had my parents watch. The nosecone didn't even budge....

Containment yes, encapsulation, no. You basically made a firecracker. Container with pyrodex, some cellulose packed down onto it, sealed up with a few strips of masking tape- that's all you need.
 
Kevin Boyd captured this D12 cato at a SoAR launch on January 26, 2013

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

Here is a shot Roger Smith got of my D-Region Tomahawk's first flight on a failed E9-8 last Dec @ TTRA Tampa.

Wow, I've never seen a black powder motor spewing out flaming chunks of propellant! Thought that was reserved for larger motors.
 
"The best CATO picture goes to.....Kevin Boyd":clap::clap: Damn impressive, I may add.

HyperLoc 300, CATO'd on first flight, rear closure failure, rebuilt, modified and flying again... :grin:

What motor was that?

Luckily I did save your decal file and this time I remembered where I put it!

Awsome video....sorry about your rocket though. Wish I knew how to edit videos like that.
 
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...

The red tracking chalk on the snow made it look like a murder scene... :)

Bad E28... Blew off the aft closure, and shot it into the blast deflector (I turned it into a necklace, it was so bent :))

Ken Allen gave me a new aft closure.

You can see the casing above the nose cone (wrapped in the streamer) in the last photo.




No damage, except for my pride.
