RAF Be2c British Reconnaissance Aircraft from 1915

The Model
We have chosen the scale of 1:5 rendering
a model size that i easy to fly but also relatively
easy to transport. Both the upper and the lower
wing panels can be removed as an assembly, for
transportation which gives relatively limited
requirement for transportation size.
The finished model is painted in 1915 livery
and further detailing can be made as per
documentation.
Specification:
Wingspan 88.4" (225 cm)
Length 65.4" (161 cm)
Wing area 2281 sq/inch (142,6 dm²)
Weight 13.7 lbs (6200 g)
Wing Load (15oc/sq' (43 g/dm²)
Engine .90 cu/inch 4-cycle(15 cc)
Covering and finish
The model is covered and painted from the
factory. If you have made changes in the engine
bearers and adapted the dummy engine to fit on
both sides of the engine, you will have to cover
the open areas with fuel proof paint.
Installation of engine.
We recommend that you don't overpower
this model. It will fly happily with a .90 standard 4stroke
engine. Our prototype was tried with a
Thunder Tiger .90 4-stroke engine, which gave
more than ample thrust. The engine bearers have
been adjusted for this size of engine.
The engine is mounted upright justifying the
need for adequate cooling. The engine thereby
is located in the "V" of the dummy engine and
covered by the "air scoop" top plate.
1. Remove the air scoop and drill the holes
in the engine plywood bearers. Fasten the engine
with blind nuts on the underside of the plywood.
Place the engine as close to the front as possible.
The propeller should be approx 1/8" / 3mm) it front
of the nose cowl.
2. Drill the holes from the tank to the
carburator, pressure tap and the filling cap.
3. Install the engine and connect the throttle
servo.
4. Make cut outs in the dummy engine block
so that this will fit in line with your engine. This
"surgery" is executed by removing a little at the
time and checking. When you are satisfied with
the fit and openings, screw the dummy engine
onto the engine mount board, using screws and
washers from under the plywood engine mount.
5. Reinstall the engine cowl scoop (cowl)
using 4 #2 sheet metal screws.
Installation of servos, tank, battery and
receiver.
The 2 aileron servos are installed in the
lower part of the servo vertical bulkhead in the
fuselage side by side using the center holes
commonly for the servos. The servo arms should
protrude below the fuselage. It may be necessary
to remove som plastoc from the servo housing to
get the servos in place..
The elevator servo and the rudder servo
are installed in the servo tray. The tank is
positioned below the plywood engine mount and
in line with and behind the engine.
The throttle servo is installed bihind the
fire wall together with the battery pack.
The receiver are positioned in the upper
part of the fuselage between the two cockpits.
The switch can be mounted on the servo
tray with extension rod or on the instrument panel.
1. Attach a ball link head to joystick 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 temporarily connect the servo arms to the
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
under the plywood engine bearer
5. Install the aileron servos in the bulkhead.
The aileron connecting wires attaches to the
servo arms. The upper part of the servo arms
are connected thus giving double thrust to the
ailerons. Deflection of the ailerons should be 20°
up and down.
6. Install the radio switch on the dash board
or the rear support in the front cockpit
7. Place the receiver and the battery pack
in the upper part of the trays, wrapped in foam
rubber and secure with rubber bands.
Assembly of the Be2c
All parts have been assembled at the factory
and only disassembled for transportation. On
recent production (serial # 9912-26 and higher)
the landing gear has been made removable. The
landing gear is pushed into the holes in the
fuselage and held in position by the 2 cross
bracing wires.
Rudder and elevator wires are factory
adjusted but may need some tensioning
adjustment after a while. Aileron can be adjusted
with the clevices connecting to the aileron horns.
Assembly of wing panels
1. Push the lower wing halves into the holes
in the fuselage.
2. Push the upper wing halves into the holes
in the wing cabane. Connect the flying wires and
the landing wires. Attach the flying wires in place.
