Unfortunately, I can not post pictures of making CF pushrods from my ailerons. Servos are so close to ailerons that pushrod (including clevises) is only 2.5inch long. Clevis is 3.4 inch long, so 1 inch is left between them. I just used 1-1/2 inch long all threaded rod (no need for CF tube). Now with such short pushrods and with servo horns moving horizontally and ailron horns moving vertically, I had to use Dubro Swivel Ball Link 2-56. For that size 2-56 is enough.

The wing is mounted with four 1/4 -20 screws. I wonder, what is the strenght of 1/4 nylon screw - can I use them or should I use metal? I estimate that RTF plane will be between 12 and 15 lb (two 6-inch wheels with aluminium LG is over 2 lb itself).
