Photos from Mayhem Day 2

Very good. thanks a lot.

Great pictures! Thanks for taking/sharing them.

If anyone is interested, here’s the link to Jason Cook’s N1100 flight.

Jason,
That was an amazing flight, and an AWESOME video. I loved the music — “we’re gonna let it burn, burn, burn, burn…” — great choice!

Great pictures! Thanks for taking/sharing them.

I’m glad you found the forum — I forgot to email the links to you 😉

Glad to be here. 🙂

Any of you who were there at the end of the last day may have seen the traumatic launch of the MadCow “Cricket.”

It went up great on an AT G80, but at ejection things got really weird. The parachute came out, but did not unfold. It hit the ground hard near some RVs.

Now the weird part:

I added a few ounces of lead chunks to the nosecone to stabilize it, as per the MadCow directions. I used a trick detailed by Apogee Components; I filled the nosecone with spray-foam to hold the weight in place. It worked perfectly, and the rocket had many great flights.

With the new DMS AT G80, (more BP?) the foam melted out of the nosecone at ejection, and covered the parachute. Thus why it didn’t open. 😯

Luckily, damage was limited. A fin popped out, but was not broken. It will be easy to epoxy back in. The tube was crushed somewhat, but CA and sandpaper will fix it.

Anyway, I felt the need to explain this weird chain of events. In the future, I will epoxy a wooden bulkhead over the foam to prevent it from melting out.
