RE: Hobby Lobby Skylark e-Conversion
To install the pre-made metal "Y" control rod for the elevator halves, I tied and then taped the strings inside the fuselage to the ends.
It was then a fairly simple procedure to draw the rods through the fuselage out the slots on each side of the tail. The split end of the "Y" rod is threaded to attach a clevis and the other end is cut to length with a right angle bend. It is held in the servo with the supplied "keeper".
The manual claims that the length of the servo end of the rod is 120mm but I found this to be incorrect. It is best to install the servo first and then the elevator control horns before cutting the rod.
I'll post some pictures of the servos and linkage after I install the pull-pull rudder.
