High-performance model glider / electric glider designed for
the beginner.
Dear fellow modeller,
Congratulations on your choice of the alpha junior / club
high-performance glider for the beginner. These are attractive
model aircraft with docile handling, and we hope you will
thoroughly enjoy building and flying your model.
MULTIPLEX model kits are subject to constant quality checks
throughout the production process, and we sincerely hope
that you are happy with the contents of your kit. However, we
would ask you to check all the parts before you start
construction, as we cannot exchange components which
you have already worked on. If you find any part is not
acceptable for any reason, we will readily correct or exchange
it. Just send the component to our Model Department. Please
be sure to include a brief description of the fault.
We are constantly working on improving our models, and for
this reason we must reserve the right to change the kit
contents in terms of shape or dimensions of parts, technology,
materials and fittings, without prior notification. Please
understand that we cannot entertain claims against us if the
kit contents do not agree in every respect with the instructions
and the illustrations.
Caution!
Radio-controlled models, and especially model aircraft,
are by no means playthings. Building and operating them
safely requires a certain level of technical competence
and manual skill, together with discipline and a
responsible attitude at the flying field.
Errors and carelessness in building and flying the model
can result in serious personal injury and damage to
property. Since we, as manufacturers, have no control
over the construction, maintenance and operation of our
products, we wish to take this opportunity to point out
these hazards, and to emphasise your personal
responsibility.

Receiving system components

The fuselage is designed to accept the "EinStein" module,
MPX # 1 4004, for the elevator and rudder. Alternatively you
can use two small servos, e.g. Micro 3BB, MPX # 6 5049.
The wings are designed to accept two MS-X3 servos, MPX #
6 5035, in each wing for the ailerons and landing flaps.
It is important that the receiver battery should be of
generous capacity to cope with the model's receiving system,
bearing in mind that you will be using up to six servos. We
recommend a 600 mAh pack: 4 cells SCR-C, MPX Order No. 15
5553, or four 1000 mAh cells, MPX # 15 5566. Extra battery
capacity always makes more sense than lead ballast.
If you are using an "EinStein" module no separate switch
harness is required, as the switch is built-in. If you are using
a conventional receiver we recommend a switch harness
with charge socket, MPX Order No. 8 5139.
We strongly recommend that you also fit some form of
receiver battery monitor. MULTIPLEX offers a comprehensive
range:
Receiver battery tester
Receiver battery alarm
Receiver battery monitor Order No. 7 5160
If you prefer a conventional receiver we recommend the
Micro 5/7, MPX # 5 5933.
For the electrical connection between the wing-mounted
servos and the fuselage we recommend the Cable Set 2, MPX
Order No. 8 5255.
A similar cable set fitted with Universal (UNI) connectors is
available under MPX 8 5253.
Important note - e.g. when repairing the D-box
For all joints involving the styrofoam D-box leading edge
it is essential that you do not use solvent-based adhesives,
and in particular avoid instant or cyano-acrylate glue
(cyano, or CA). These materials will melt and destroy a
large volume of foam, and the component will be
completely ruined. Use solvent-free adhesives, such as 5-
minute epoxy or white glue.
