FINAL ASSEMBLY
INSTALLING THE SPINNER
Install the spinner back-plate, propeller and
spinner cone. The spinner cone is held in place
using two 3mm x 15mm wood screws.
The propeller should not touch any part of the
spinner cone. If it dose, use a sharp modeling
knife and carefully trim away the spinner cone
where the propeller comes in contact with it.
INSTALLING THE RECEIVER AND BATTERY
1. Plug the servo leads and the switch lead into
the receiver. You may want to plug an aileron
extension into the receiver to make plugging in
the aileron servo lead easier when you are
installing the wing. Plug the battery pack lead
into the switch.
2. Wrap the receiver and battery pack in the
protective foam to protect them from vibration.
Use a rubber band or masking tape to hold the
foam in place.
3. Strap the battery pack and receiver onto the
wing joiner tube in the fuselage.
Do not permanently secure the receiver and
battery until after balancing the model.
4. Using a 2mm drill bit, drill a hole through the
side of the fuselage, near the receiver, for the
antenna to exit.
!
!
BALANCING
1. It is critical that your airplane be balanced
correctly. Improper balance will cause your plane
to lose control and crash.
THE CENTER OF GRAVITY IS LOCATED
85-90mm BACK FROM THE LEADING EDGE
OF THE WING, AT THE FUSELAGE. This
location is recommended for initial test flying and
trimming. There is a 10mm margin forward and
aft. BALANCE A PLANE UPSIDE DOWN WITH
THE FUEL TANK EMPTY.
2. Mount the wing to the fuselage. Using a couple of
pieces of masking tape, place them on the top
side of the wing 85-90mm back from the leading
edge, at the fuselage sides.
3. Turn the airplane upside down. Place your fingers
on the masking tape and carefully lift the plane .
4. If the nose of the plane falls, the plane is nose
heavy. To correct this first move the battery pack
further back in the fuselage. If this is not possible
or does not correct it, stick small amounts of lead
weight on the fuselage under the horizontal
stabilizer. If the tail of the plane falls, the plane is
tail heavy. To correct this, move the battery and
receiver forward or if this is not possible, stick
weight into the firewall. When balanced correctly,
the airplane should sit level or slightly nose down
when you lift it up with your fingers.
FLIGHT PREPARATION
PRE FLIGHT CHECK
1. Completely charge your transmitter and receiver
batteries before your first day of flying.
2. Check every bolt and every glue joint in your
plane to ensure that everything is tight and well
bonded.
3. Double check the balance of the airplane
4. Check the control surface
5. Check the receiver antenna . It should be fully
extended and not coiled up inside the fuselage.
6. Properly balance the propeller.
LATERAL BALANCE
After you have balanced a plane on the C.G. You
should laterally balance it. Doing this will help
the airplane track straighter.
5. Turn the airplane upside down. Attach one loop of
heavy string to the engine crankshaft and one to
the tail wheel wire. With the wings level, carefully
lift the airplane by the string. This may require
two people to make it easier.
6. If one side of the wing fall, that side is heavier
than the opposite. Add small amounts of lead
weight to the bottom side of the lighter wing
half's wing tip. Follow this procedure until the
wing stays level when you lift the airplane.
