If necessary, carefully lengthen tape to stick the pushrod to the wing. The the slots to reach a perfect fit between pushrod should run parallel to the servo aileron and wing.

- Page 11 Apply some oil to the mounting screw and blind nut thread and mount the wing in place. The oil will prevent the screw from getting locked in case a little bit of epoxy will come to close. Turn the plane around. Epoxy/Micro Balloon paste should have been pushed out between the wing and the fuselage.

The rudder horn can either be installed beside the exhaust duct as shown above or installed below the exhaust duct so that it is hidden inside the fuselage.
- Page 16 Prepare the elevator servo. The servo will be glued to the bottom of the fuselage directly behind the elevator recess. Wrap the servo in heat shrink tube. Roughen the surface. Center the servo with your radio and install the servo arm as shown. The Servo will be installed in the fuselage as shown above.
