2- Joining the wing
Before gluing:
- Draw the center line on the wing joiner.
- Trial fit each part before gluing . Be certain that there are no gaps.
If the parts will join, but with a gaps, sand or trim the parts a little
at a time until the parts meet exactly with no gaps.
- Check for the correct dihedral angle

Depending on the position of the linkage, determine the location of aileron control horn.
The horn holes must be perfectly aligned with the axis of articulation.
Mark the position of the “foot” of the horn on the aileron. Then, with the drill, make the 2 holes.
Install the aileron control horn as shown.

sure that the ends of the struts are inserted into
the holes in the landing gear channel.
2- Position the four nylon straps across the landing
gear struts. Using the eight 3x12mm screws
located in the hardware bag, fasten the landing
gear to the bottom of the wing as show.
3- Slide one wheel onto each of the
landing gear axles and secure them
with the supplied wheel collars

* WARNING: When removing any covering from the airframe, please ensure that
you secure the cut edge with CA or similar cement. This will ensure the covering remain tight.
Cut away only the film

6- Stabilizer
1-Slide the vertical and horizontal stabilizer on the fuselage, use a pencil to trace around the bottom and the top (horizontal stabilizer) and the right and the left
(vertical stabilizer).
2-Remove the vertical and horizontal stabilizer from the fuselage. Careful cut away the covering inside the lines which were marked in steep 1.
Cut away only the covering both the left and right side*
Note: Check the alignment of the horizontal stabilizer by measuring from a fixed point along the center line of the fuselage to the leading edge on each side of the horizontal stabilizer. The distance must be equal on both sides. If not, adjust the stabilizer until the measurements are the same.

Realign the vertical stabilizer and horizontal stabilizer, then glue the vertical stabilizer and horizontal stabilizer into the fuselage, using a generous amount of thin CA.
Note: glue both the right and left of the vertical stabilizer, and both the top and bottom of the horizontal stabilizer.

Do the same way with other elevator and rudder
Push the elevator and its hinges into the hinge slots in the trailing edge of the horizontal stabilizer. There should be a minimal hinge gap.
When satisfied with the and alignment, hinge the elevator to the horizontal stabilizer using thin CA glue.
