In the photos, the Gaudius without a nose is mine. I thought I'd better comment on it because there are a couple of lessons to be learned.
Lesson 1:
If your airplane is acting erratic, land. On my first flight on Saturday which was my third flight of the contest which was Round 4 for me, I had some major flaws, one so bad on the Top Hat that I went around and did it again. I was having some trouble seeing it in the haze which really scatters the sunlight, and so I blamed it on myself. The format that we used required that we fly again in about twenty minutes so I didn't even discuss it with anyone and took off for flight number two. On the very first pull up for the Half Clover, it did almost the exact thing it had done on the pull up into the Top Hat on the previous flight. My thoughts were clear, don't give up. I blame that on having recently read Seal Team Six. Those guys never give up. The long and short of it was that after a few more bad maneuvers the plane went into a death spiral/spin and impacted the hard desert right on its nose which happens to be a Contra Drive. At that time I figured the radio had quit but still didn't believe my earlier troubles were caused by that and so didn't recognize that I should have landed and found out what was wrong. It is so obvious now.

Lesson 2:
Make sure your wing and stab tubes, including anti rotation tubes are secured so they are not able to move. When we saw the airplane, you could see the horizontal stab on the left side was at some odd ball angle and the the anti rotation tube had migrated into the right stab to the point it was not engaging the left stab. The rear tube was secured to both stabs with small screws designed to keep the stabs from sliding off, but are not designed to keep them from rotating on that tube under heavy loads. I suspect they kept the left stab in rough alignment for awhile but eventually allowed some serious angles of attack in both directions. I'm pretty sure I saw it reverse the spin at least once from about 400 feet.
