Servoed Hammerhead: Drone linkage

[grr I cant just cut/paste this whole project... this site doenst allow links to be pasted, or something, so I'm going to have to redo it all.]

I plan on using the curved cradle mount in the wing to hold the drone disk in place, since it covers approx 70% of the drones' circle. So, running on that assumption, I got right to work modifying the drones to accept the pushrods and also to have room for the pushrods motion.

I wanted to keep the mechanism that moves the drones invisible, so, notched out the side of the disks in the area where the rods will be. This was also a good place to have the rods go from the wings' point of view: this slot is right where the meat of the wing is.

Heres a sample layout of the rod, showing how it enters the circles area, and the vertical part (hard to see, sorry) is the hook, that will attach to the drone. At the moment its empty space, but the other piece of the drone will be where the hole actually goes. The hole will be directly to the read in the arc of the circle, and that will be the neutral position, to give the largest arc of movement in each direction.

Here the drone is assembled, and the hole is seen, with the rod sticking out. Some fine shaving and tuning was required to keep the rod pivoting in its hole smoothly, and to sweep through the midst of the drone and slot going smoothly as well. All of this was important; I wanted to avoid any binding of any sort.

This view shows the hole in the wing, and in general shows how everything is set up.

Here the rod is inside the hull, and the position of the holes, and the straight rods, is just about where I wanted it, to give the most room for the servo and its control +.
