NOTES FOR ASSEMBLY
Please refer to this manual for assembly instructions for this model.
Follow the order of assembly indicated. The instructions are divided into chapters, which are structured in a way that
each step is based on the work done in the previous step. Changing the order of assembly may result in additional or
unnecessary steps.
Use thread lockers and retaining compounds as indicated. In general, each bolt or screw that engages with a metal part
requires thread lock.
Factory pre-assembled components have been assembled with all the required thread lock and lubricants,
and have passed quality control. It is not necessary to disassemble and re-assemble them.
We do not recommend the use of thin cyanoacrylate glue for surface mount of painted parts. The fumes of the curing
glue leave white stains on the clear coat, which are hard to remove.

STEP 1 HINGING FLAPS/AILERONS/ELEVATORS
1. Apply instant CA glue to aileron, outer flap, and pin hinge
Use a rotary tool and 1/16-inch (1.5mm) drill bit to drill a 1/2-inch (12mm) deep hole in the center of each hinge slot.
This provides a tunnel allowing the glue used to secure the hinges to fully penetrate the hinge. Slide the hinges
back into the ailerons and outer flaps and apply CA glue.
2. Install the aileron and inner/outer flaps into the main wing
Slide the aileron and outer flap into position on the wing. Make sure the inboard edge of the flap near the center
of the wing, and the outer tip of the aileron near the wing tip do not bind against the wing. Also make sure the flap
and aileron do not bind against each other.

3. Glue aileron and outer flaps into the main wing
Push the aileron/outer flap tight against the wing. Flex the aileron and apply enough thin CA to fully penetrate the
hinge. Apply CA to both the top and bottom of the hinge. Important: Do not use accelerator when hinging. The
CA must be allowed to soak into the hinge for the best possible bond between the hinge and surrounding wood.
4. Check and break in aileron and outer flaps
After the CA has fully cured, gently pull on the wing and aileron to make sure the hinges are secure. If not, re-glue
the hinges.
To break in the hinges, you will need to flex the aileron up and down a number of times.

5. Hinging the elevators
Use medium grit sandpaper to sand the tipped flap torque rod ends (7). Use rubbing alcohol and a paper towel to
remove any debris from the torque rods. This will aid in strengthening the bond between the flap torque rod and
flap. Enter both torque rods into the wing and join them with the T-Junction (8). Make sure to use Loctite to secure
the set screws, and make sure that both torque rods are aligned in the same plane. Also make sure that the T-
Junction is app. 90 degrees positioned relative to the torque rod plane to allow maximum flap travel before
tightening the screws. Hinging the flaps follows the same procedure as the ailerons, except you will need to apply
30-minute epoxy to the torque rods that enter the flaps.
