Correct yes, it's for elevator servo.


Roughly filled the gap with microballoon around the main wing support.

I attached rudder handle to the bottom part of rudder, so bottom part is easier to make.

I filled the remaining space with pieces of styrodur and glued them together with polyurethane glue.

Covered the whole surface with 25g glass fiber and 2 extra layers on styrodur part to make it tougher.

Because rudder is quite massive, edges are a bit thicker.

At the end of the stick I put glass fiber and soaked it with epoxy, leveled it up with lathe and made thread so it can be pulled out using screw.
