I finally managed to complete my C140 after over a year of rather slow building and after 1 & 1/2 gallons of flying I was really liking it. Made me look much better than I really am . After watching a great flight with Luke flying his C140 I had a few things to try and do my best to try and follow it.....

Flight was going well but unfortunately it wasn't to be [&:], about half way through I lost all control of the elevator whilst flying slowly into wind at about 40'. From there it just porpoised into the ground at about 45 degrees. It is now a big jigsaw puzzle . Possibly repairable since the wing spar stayed intact - amazingly despite damage all around. Cowl new on that flight certainly doesn't look new anymore.

The cause I found to be the pin in the metal clevis seperated from the rest of the clevis. I used the stock location for a single elevator servo and Malcolms elevator joiner. I had just switched to a thick metal arm to get more movement, which I now realise allows no play for the clevis to move vertically and therfore is always being bent whenever the servo is moved. Nothing seemed to be binding and no strain on the servo was evident otherwise. When I rebuild I am going to try a different location for the elevator servo - haven't decided where yet though. Could take me a little while.
