Important note
This model is not made of styrofoam™, and it is not
possible to glue the material using white glue or
epoxy. Please be sure to use cyano-acrylate glue
exclusively, preferably in conjunction with cyano
activator (kicker). We recommend medium-viscosity
cyano. This is the procedure: spray cyano activator
on one face of the Elapor®; allow it to air-dry, then
apply cyano adhesive to the other face. Join the parts,
immediately position them accurately, and wait a few
seconds for the glue to harden.

Please take care when handling cyano-acrylate
adhesives. These materials harden in seconds, so don’t
get them on your fingers or other parts of the body.
We strongly recommend the use of goggles to protect
your eyes. Keep the adhesive out of the reach of
children.

1. Before assembling the model

Please check the contents of your kit.
You will find

Figs. 01 + 02

and the Parts List helpful here.

The illustrations which refer to completing your RR model
are marked RR + KIT. The pictures marked with KIT only
are just for your information, in case you need to repair the
model at any time using replacement parts.

2. Opening and closing the canopy

Hold the front of the canopy moulding and pull it upward;
this opens the canopy.

To close it again, insert the rear locating lug, push the
canopy back as far as it will go, and press down the front
until it engages.

Final assembly

3. Tailwheel option

A tailwheel can be fitted to the model if you wish. This is
optional for the land-based version, but is essential if you
intend to install floats later, because a water rudder is
required for this version, and this is fitted to the tailwheel
wire.

Figs. 09 - 13

show the procedure.

A bending template is shown in

Figs. 12 + 12a

. The steel

wire

has a diameter of 1.3 mm. The sleeve

is supplied

in the kit.

Installation:

Pierce a tunnel through the tailplane and the fuselage as
shown in

Fig. 11

. Note that the foam tailskid has to be cut

away if you fit the optional tailwheel. Cut a notch in the
rudder for the actuating wire.

Fig. 10

Glue the sleeve

in place using cyano, and cut it to

length as shown. The final, upper bend in the tailwheel
wire

should only be made after fitting it through the

sleeve

One further option:

For float operations a water rudder has to be cut from 3
mm Depron. It is fixed between the wire frame using
adhesive tape, and attached to the tailwheel wire using
two collets. These parts are included in the float set.

4. Installing the motor

The model is fitted with a Permax 400 motor as standard.
However, you may wish to install an upgrade power plant.
We recommend the following two options:

A. Standard G Permax 400 with 3 : 1 gearbox

Fig. 20

Easy Glider E power set
(3 : 1 gearbox with Permax 400)

# 33 2688

plus 3.5 mm Ø propeller driver

# 33 2310

and

8 x 3.8” propeller

# 73 3139

B. “Sport” power set BL-X 22-18

# 33 2627

This includes speed controller, propeller driver and propeller

5. Connecting the motor

Carry out a test-run! The motor shaft / propeller must rotate
anti-clockwise when viewed from the front. If not, reverse
the connections at the motor terminals.

6. Releasing the elevator and rudder

Move the rudder and elevator to and fro repeatedly at the
hinge line to free up the hinges. Do not cut off the control
surfaces!

Figs. 25 + 27

7. Gluing the tail panels to the fuselage

Position the tailplane on the fuselage “dry” (no glue), and
check that the parts fit together accurately. Ensure in
particular that the tailplane

rests on the fuselage without

any gaps, and is parallel to the wing saddle. Check this
by laying the wing on the fuselage and sighting over the
wing and tailplane from the nose. When you are confident
that the tailplane can be aligned properly, it should be glued
permanently to the fuselage. Check alignment once more,
and ensure that it fits snugly before allowing the glue to
cure fully.

Place the fin on the fuselage “dry”, and check that it fits
correctly. In this case ensure that the fin

makes good

contact, without gaps, and is at 90° to the wing saddle
and the tailplane. Use a setsquare to check this.

8. Retaining the elevator and rudder pushrods

Slip the end of the two steel pushrods

and

through

the pushrod connectors

. Set the servos and control

surfaces to centre (neutral) and tighten the socket-head
grubscrews

to lock them. You may need to bend the
