Hi there all, was hopin someone out there can help. I recently had a 40 TT Super Decathlon built for me. It has completed about ten incident free flights, when after the tenth flight, I just turned it around on the RWY and took off again. As soon as I lifted of it started a very eratic uncontrolled oscilation about all the axes. Needless to say, it got worse until the aircraft crashed. One reaching the a/c I found all the servos jumping around wildly. Now they do not stop chattering and making wild uncommand movements. When I do a range check with the engine off, It is fine until I move about 10ft away, and then it starts gyrating wildly, witht he servos moving way past their full travel ranges. I am aware of metal on metal interferance, however all of the normal fixes have not yet been sucessful. I have a pull pull rudder installed, and was wondering if I had to remove it and replace one of the pull pull wires with a plastic coated wire. I notice that it has the two wires touching. The other possible problem is that I see the throttle linkage is connected directly onto the carb arm. How could all this change after about 10 flights? I am very confused and have just about dismantled the whole model and still found no cure.
