Default RE: Goldberg Extra 300

She's done.
If you look at the picture of the elevator you will see that it came off clean. This was due to me installing the pushrods incorrectly. I used metal rods screwed into the end of the inner piece but the junction should have been inside the outer tube. After about 70 flights this inner rod bent and then broke right at the connection. Leaving no connection to the elevator. This allowed severe flutter at the bottom of a downline which took the elevator off. Without one side elevator the other side must have folded as well. It went in at nearly half speed. I only managed to get thethrottle pulled back at the last 20 feet.
I have learned a valuble lesson about pushrods. The gasser I am building now has the servos in the tail. No long pushrods.
