The wing servo installation was pretty straight forward. We extended the wires by cutting and splicing rather the using the extensions called for in the instructions. The servo covers should be cut larger than the lines provided.

We chose to exit the rudder push rod through the rear or the fuselage rather than the side. The only problem was this increased the throw to more than the instructions called for. This was solved by limiting the throw in programming.

The elevator servo cannot be mounted per the instructions. In order to open enough space to get the control horn, servo, and wooden servo mount provided you would have to take most of the structure at the top of the vertical stab. We liked the idea of using screw to attach serve rather that glue so we glued a small wooden tab to the back of each servo ear. The servo was positioned on the outside of the fuselage and three holes were drilled in the stab. Once we finally got the servo assembly into the stab we used a very bright flashlight to shine through the opposite side of the vertical stab and line up holes we drilled with the servo ears and installed the screws. BTW, the kit came with a ball and socket mount for use here. We used a metal clevis instead.
