1. Locate the trim line on the windscreen; it will be a small
recessed area showing where to cut for the proper shape. Cut
the windscreen a little at a time on this line with sharp scissors,
or canopy scissors. Test fit the windscreen often and trim it as
necessary. When you are happy with the fit, glue it in place
using canopy glue. Clear tape may be used as well, as
desired. Note: Do not use CA, it will fog the plastic.

1. Connect the wire pushrod to the second-from-the-
outer hole in a nylon control horn. You may have to enlarge
the hole in the horn using a sharp hobby knife.
❏
2. Locate the pushrod exit tubes at the tail end of the
fuselage. They are located just forward of the horizontal
stab. If you cannot see them, feel for the slight indentation
through the covering or insert the pushrod into the pushrod
tubes inside the fuselage, and push the pushrods against
the covering. Cut the covering away from the pushrod exit
with a sharp hobby knife.
❏
3. Slide the straight end of the pushrods into the fuselage
from the tail.
❏
4. Position the control horn so that the pushrod mounting
holes are aligned with the hinge line. Mark the location of
the control horns’ mounting holes on to the elevator and
rudder control surface. Drill two 1/16" [1.6mm] holes where
you marked them.
❏
5. Using the 2 x 10mm machine screws provided, attach
the nylon control horn and tighten with the nylon back plate.
Be careful not to crush the wood when tightening.
❏
1. Test fit the servo tray as shown in the photo, but do not
glue it in place. This will allow you to move the tray forward
or aft to assist with the balancing of the model.
