Last Saturday, I was flying my e-7SE at the end of the 3rd flight pitch felt funny, so I up I went nice and high, hit throttle hold and started auto down, when I noticed my head was not coming as fast as normal, made the auto a little bounce not much. Then I went to pick it up and was shock, the main shaft move up and down a lot. I had pushed the center of the middle main shaft bearing out. This ship I bought use and put almost 2000 flights on it. These ship are unbelievable auto with the collar running on the middle bearing block lots of drag, and still auto in. Matt you build a great machine Ordered 3 new main bearing. Then people wonder why I have 516,e-5s, and a e-7SE, and have to have a 766 too. Cliff
