Elevator Trim Servo Linkage

Finished up the control linkage for the elevator trim servo. I had to modify the tab to fit the servo clevis. First, I had to drill a smaller hole to fit the pin for the clevis.Then, I needed to shape the tab to allow complete rotation to its limits both up and down. None of this was ground breaking, I found and followed the ideas on the Wings Forum from others that had done the same thing.

So, after drilling the hole and filing the tab to final shape I connected the clevis to the tab and servo, then using a 9 volt battery, I was able to test movement to its limits both up and down with no binding. Works perfect.
