The aileron linkage you have shows a set screw cable lock type fastener on the servo horn. I would not recommend using that when you fly. Use a solder on clevis for a more positive anchor, as they are much more positive / less likely to slip or loosen.
I was wondering when somebody was going to notice that.
I had used those connectors successfully on my smaller planes and initially was going to use them on this, but I figured with the extra size & torque I would be pressing my luck.
I plan to buy a 4-40 die set & thread the servo side of the pushrod and use dubro ball links. I just used the E/Z links to line up the linkages because I haven't bought the ball links yet.
