Just thought people might find this interesting.

This Sumo is almost two years old now, with seven flights under its belt, but I still enjoy it because of its excellent reliability!

For the record, the rocket weighs 55oz with a G64-4W loaded, flys off of a 1/4" diameter, 4' long rod, and never fails to put on a good show!

I've had some flawlessly straight boosts, but in all the others, it exhibited a slight lean, with apogee right at the top, every time!

Here's my Sumo model.

It's made only one flight (So far ;) ) which was at NARAM-52 using an AeroTech G80-7T motor. Great flight! :)

Well, below is a good flight and one very bad flight (kinda fun to sequence through the frames though and relive the carnage)...

Your cat looks sooooo excited! LOL

Great looking Sumo, too.

WHAT HAPPENED? :y::eyepop:
Fun! fun! Let's see... My first reload. Put in the delay/spacer combination in backwards. Noticed it and got some real-time coaching from an L3. He told me to push it out through the fore BP hole (he apologized afterward) and reinsert it correctly. Not a good idea as it was in there very tight and it put a "pinhole" in the delay. Subsequently the amazing flame. Really, should have known better. But no big deal--live and learn everyday.

Do you have any pictures of the aftermath?

Well, as you can imagine, it was, ummm scorched(!!!!). The top of the airframe was charred ash (fuzzy first pic after I cut off the "charcoal" and stripped off the inside burnt "confetti" with a test fit of an outside coupler that didn't work). Two of the fins were melted on the ends--those were easy though, I cut the melted part off and took a file and rounded the tips. Amazingly I was able to repair the whole thing though. I had to put an coupler on the inside of the the fin can and extend the frame (second pic). In conjunction with that, I added an outside coupler and new CR to extend the motor mount (third pic). Finished inside with u-bolt to attach shock cord is shown in the fourth pic. In the end the result was great as I flew my "Stretch Sumo" successfully for my L1 cert (fifth pic with the flame motif so apropos).

Was that G80 the new 137 Nsec version? From the photos the flame is actually visible. I'm impressed!

How was the 7 sec. delay: early, late, indifferent?

The 137 Ns G80 does indeed have a visible flame. It's a significant improvement as compared to the old one.

Yes, it was the 137 N-sec version. One can really see the blue flame.

In the case of my Sumo, the seven second delay seemed perfect. :D

It's painful when you see it happen, but it's always fun to rewatch later. This one was particularly spectacular.

I see the partially destroyed plastic front end of the baffle lying next to the rocket. Did the cap that holds the ejection charge in get blocked somehow? A baffle creates a slight resistance to the ejection charge gases. If your retainer wasn’t glued on well, or if the glue bond for the retainer broke on a hard landing, or the retainer cap broke on a previous hard landing, then the ejection charge would blow the motor out of the rocket instead of the parachute.

I would have guessed the steel wool corroded / compacted, overcontaining the ejection charge and damaging both the baffle and retainer instead of hanging out the laundry.

Was the MMT split?

There was no retainer left and I didn't use the steel wool. I had a Nomex blanket
