Making Z bends in control rods
Make it easier on yourself....put a 90 degree bend in the rod, run it up through the servo arm, and put a 1/16" wheel collar on it. If the push rod is larger than 1/16" drill it with the next size drill bit (5/64"). This doesn't stress the wire, or your nylon servo arm by forcing it around the bend, and is easily removed if needed.
Is it strong enough? Holds your tail wheels on, doesn't it? I have been doing this for 26 years with no failures. It works well, guys...
