the upper center section (4 Allen 6-32 screws.
Either one of the 2 aluminum panels can now
be removed by unscrewing the sheet metal
screws. Note that different length of screws
have been used for the various locations. The
rubber coaming can be removed and later
replaced without using glue. The center section
is held down by the windscreen , which can after
removing one screw be swung to the side
releasing the panel.
1. Attach a clevis or ball link head to joy-
stick and rudder bar in the appropriate holes. You
may have to enlarge the holes to take the screw
from the ball link (Dubro #189 set of 2).
2. Install the servos for rudder and elevator
and connect the servo arms to the clevices or
ball links. Deflection for elevator is 20° up and
down and for rudder 30° right and left.
3. Install and connect the throttle servo in
the fashion you prefer.
4. Install the tank in the available space at
the right side of the engine compartment.
5. Install the aileron servos in the wing root.
The hatch cover is secured with 4 #2 sheet metal
screws. The aileron connecting rods attaches
to the servo arm. Differential throw on the aileron
is recommended Deflection of the ailerons
should be 25° up and 15°down.
6. Install the switch on the instrument panel.
7. Place the receiver and the battery pack
in the upper part of the tray, wrapped in foam
rubber and secure with rubber bands.
Assembly of the Bristol F2B Fighter
All parts have been assembled at the
factory and only disassembled for transportation.
Rudder and elevator wires are factory
adjusted but may need some tensioning
adjustment after a while. Ailerons are adjustable
with the clevises to the connecting rod and to
the aileron horn.
Assembly of the tail unit
1. Secure the top and the bottom fins with
the brackets using #2 sheet metal screws. The
rudder is permanently attached to the fins.
2. Push the stabilizer with elevators on the
brass tubes in the fuselage. Connect the sup-
porting wires with clips in their respective
positions. See rigging sketch.
3. Connect the elevator wires. Note that
these wires are crossed.
4. Connect the rudder wires. The wires for
the stearable tailskid are installed from the
factory.
Assembly of wing panels
Flying- and drag-wires are 90 lb. breaking
strength, all other wires are 40 lb. breaking
strength.
1. Push the lower wing halves into the holes
in the lower wing center section and connect the
servo leads to the Y-cable.
2. Push the upper wing halves into the
holes in the upper wing center section. Connect
the flying wires and the landing wires. Start with
the landing wires that are attached to the upper
wing cabanes. Insert the inner pair of the
interplane struts (the forward is shorter).
3. Now connect the flying wires to this
interplane strut pair. Proceed with the next bay
repeating the procedure.
4. When all struts have been installed, you
can connect the X-bracing for the interplane
struts.
5. Last the drag wire are attached to the
fuselage at the fitting behind the radiator.
6. When both wings sets have been
assembled you will have to connect the ailerons
with the interconnecting rod. This has clevises
in both ends to ease assembly. Check that the
distance is correct and adjust if necessary. The
ailerons must be parallel on both wing halves.
7. Lock the wing halves in position with the
four #2 sheet metal screws. The tabs are affixed
to the wing sections.
8. Check the dihedral. It should be 2.5" /6,5
cm measured at each tip of the lover wings. If
necessary you can adjust the dihedral by tight-
ening and loosening the flying- and landing wires.
You need not touch the interplane crossbracing.
Disconnect the wires and start adjustment with
