Sid, I'll do my best to explain how mine is set up. I'll get some pictures in a few days and you will see it's really quite simple. First, the stick is mounted through a cutout slot in the top and bottom of a piece of 2-1/8" aluminum round tubing-1/8" wall thickness. The slot has flat aluminum pieces welded in the sides of the slot on the bottom side, with flat pieces welded on the top side of the tube with tabs that stick up about 1/2" above the top surface of the tube. These tabs are drilled for a pin with brass bushings. The stick is pinned through these tabs so it can pivot fore and aft. The stick extends through the slot in the bottom of the tube and slides against the flat plates on the sides. When the stick is rotated side to side, it rotates the large tube side to side also. The stick is mounted approximately 1" back from the front end of the tube. There is a smaller piece of tubing welded to a flat plate and bolted through the front spar.The larger tube is slid over the end of the smaller one and rotates around it. The push-pull tube for the elevator is pinned to a fork at the control stick and fits inside the large tube. At the aft end of the large aluminum tube There is an aluminum plate with a hole in the center large enough to allow the push -pull tube to slide through it. The push-pull tube goes to a bellcrank mounted just behind the rear spar, where the elevator cables are attached. The flat plate that is welded to the rear of the large tube has control tabs that are at the top and bottom. The aileron push-pull tubes are attached to the tabs with rod ends and go to the aileron bellcranks in the stub wings.There is a collar welded around the large aluminum tube in front of the rear spar, Before the aluminum plate was welded on, There was a piece of tubing welded to another flat plate and holes drilled in the flat plate to bolt through the rear spar from the back side,This was slid over the larger tube before the last plate was welded on to the rear of the tube. You simply bolt the first flat plate on the aft side of the front spar, Then slide the big tube through the rear spar and slip it over the tube at the front spar. The flat plate at the aft side of the rear spar is then bolted to the rear spar and the aluminum tube is captured between them. It rotates side to side and the stick pivots fore and aft. I hope you understand all this.I know it sounds complicated but when you see the picture you can see how simple it really is.
