It is necessary to connect the circuit to a receiver channel controlled by a 3-position switch on the radio.
When the system is connected to the battery, the circuit performs a self-test by turning on all the lights for 1
second, indicating its perfect functioning. The radio control switch in the maximum position turns on the circuit,
turning on all the lights (fixed and flashing), in the middle position, it turns off only the landing lights and keeps
the navigation lights on and in the minimum position turns off the circuit, turning off all the lights.
Note that the boards are labeled on the right (green light) and on the left (red light). To pass the lighting kit
wires inside the wing, position it with the tip up and insert a thread with a weight tied to the tip through the
hole in the wing tip until it comes out through the front hole in the wing root. Tie the connector of the wing
light extension to the end of the thread at the end of the wing and carefully pull the connector to the root of
the wing, leaving the light board of the wing tip on the outside. With a 90º bent wire, pull the wires from the
landing light board through the opening in the leading edge of the wing and pull the plate to the outside. Repeat
the same process for the other half of the wing.

To fix the main board on the model airplane, the boards on the wing tips, landing lights and rudder board,
use 3M high-adhesion double-sided tape (red). Before gluing the tapes, apply 3M 8250 adhesion promoting
primer to the contact surfaces for a good result. The landing light led and resistor are shipped without soldering
as an option (see details in the enclosed leaflet). With Johnny Simões scale retracts the led is included and
installed, requiring only welding the wires.

The clear parts for navigation lights and wing landing lights are supplied in a thermoformed set. Cut out the
parts of the set with very sharp scissors and then remove the back and sides following the embossed reference
line. With a 280 to 320 fine grit sandpaper, finish the cut parts, sand the inner ends of the clear parts without
excess and in the places of the wing where the parts will be glued for better adhesion. Note that there are 2
right parts and 2 left parts. To glue after installing the light kit, use white canopy glue and attach the clear parts
with good adhesion masking tape, allowing to cure for 12 hours. After curing, remove the tapes and clean any
