Thanks for the replys, I hope my engine runs like yours Bgold. I am almost done with the pitts. It is built lite and I had to fit the bottom wing to the fuse. It set with the trailing edge up so the hold down bolts didn't fit. Also the (I) strutts were way off until I sanded down the wing saddle to line up. I am talking lowering the back edge 1/8 inch. After that they fit. I wanted to change the pull-pull elevators, they go to one servo one side is up for both elevators and the other side is down. It will be a while before I fly it,will post results when I do. Wayne
