Default My Spectra Tucked in and Ate It.

Tuck ate my Spectra over the weekend and I thought I'd share.

It was windy. Too windy, actually. Down at the Bluff by the beach.

I had added 1/6 oz. of lead to the tail to make the plane more fun to fly. It turned on a dime. Then came Saturday.

I flew up in the windy sky. It was fun. I was flying down wind when all of a sudden . . .[X(]

I turned back into the wind and was struck by a gust about 500 feet up. The nose went down and the plane gathered speed. I pulled back but it didn't do any good. Down down down she dove, finally vertical and then beyond.

The rudder still worked. I could keep it from crashing into the parking lot, barely. I guess I should have let it tuck all the way and flown it out inverted.

Shattered fuselage and broken wingtip, new fuse on the way. Thought I'd share.

A stiffer supported pushrod..
Yours probably bowed under the load when trying to push the elevator up.
Tuck -is- a symptom of an aft c.g.
And it must be corrected very quickly, or the plane goes down..

Yeah, I did a search in "Sailplanes." Best quote: A nose-heavy plane flies poorly, a tail-heavy plane flies once.

I think you're right about the pushrod and will take care to ensure that doesn't happen again.

When ever possible I mount the elevator rod so that it pulls for up elevator. If not possible I support the rod well, and even consider using a stronger rod (4-40 instead of 2-56).
