Mr. Twisty had a bad day.
C11-5 ejection charge failure.
Luckily it just rained so the ground was soft. Nose cone buried 5 1/4" but no damage to the body tube.
One fin popped off due to the shock but minimal damage (I purposely use "weak" glue so fins pop when they come down through trees instead of shattering).
Video of failure here.

Incase anybody was worried about Mr. Twisty- he's OK.
Some minor paint damage but he glued back well and lines up.
Tomorrow is forecasted to be 0mph wind at 7 am so I'll try to get a D12-3 launch.

How hot does it come in? Slow enough to fly at a public launch?

My first video with the C11-3 launch back on page 1 has a pretty clear shot of the landing. I wouldn't want to stand under it but the landing was pretty mild.
The other video with the engine failure was pretty violent- but then if it had been a High Flier XL or other large rocket with an engine failure it would have been just as bad I guess.
I've never been to a large public event so I'm not sure how they're setup for safety or contingency plans for chute failures and such.

I was actually toying with a 3 fin design last night- it might be a better option for these larger models to increase launch stability and recovery drag to slow it down a little more on landing.
Of course that would no longer be an "upscaled Tazz" but I think veering off the line to make a more enjoyable model would be a fair trade.
