Building and Operating Instructions - ASW 28 GRP 3m
No. 2585

Dear customer,
Congratulations on your choice of a GRP model glider from
the robbe Modellsport range. Many thanks for placing your
trust in us.
The model can be ready for the air when you have completed
just a few simple procedures. Please read right through
these instructions and the separate information sheets
before attempting to assemble and fly the model, as this will
make it much easier to complete the tasks required.
Draw the servo extension leads through the wings and
fuselage before installing the aileron, airbrake and elevator
servos. Secure each plug and socket connection with a heat-
shrink sleeve.
Please study the illustrations and the brief instructions to
obtain a clear understanding of the individual stages of
construction. All parts must be trial-fitted “dry” (without glue)
before you reach for the glue. Assign the individual compon-
ents to the various stages of assembly.
All directions, such as “right-hand”, are as seen from the
tail of the model, looking forward.
We are constantly working on our products, striving to ensure
that they reflect the current state of technology.
You can find

mentation on the Internet by calling up the appropriate

Notes regarding the radio control system
For this model you require a radio control system with at least
eight channels, so that you can adjust control surface travels,
servo neutrals, servo directions and Expo at the transmitter.
We particularly recommend 2.4 GHz systems.
Each aileron and each airbrake is actuated by a separate
servo.
For the wing-mounted servos a good option is the S-Bus sys-
tem, which requires a suitable receiver and matching servos.
See the separate S-Bus instructions for installation details.
You will find wiring diagrams for conventional wiring and S-
Bus wiring on the penultimate page of these instructions.
The text and the photos cover the conventional
servo installation with separate extension leads running to
the receiver.
Before you start construction, ensure that your receiving sys-
tem components will fit in the model where shown.
if you intend to install system components other than those
we recommend, you can still follow the same basic arrange-
ment shown in the diagram.
You may need to make minor adjustments to compensate for
differences in component sizes.
Set the servos to neutral from the transmitter (transmitter
sticks and trims central) before installing them.
Remove any output discs or levers from the servos.
Always switch on the transmitter first. Always switch off the
receiving system first, and only then
the transmitter.
When installing or setting up the receiving system com-
ponents, be sure to read and observe the instructions
supplied with them.
You should also read right through the instructions and
safety information supplied with the battery pack and
charger before using these items for the first time.
Colour scheme
The model components are supplied as standard with a white
pigmented finish, so
no painting is necessary.
Joining the components, recommended adhesives
All parts must be trial-fitted “dry” (without glue) before you
reach for the adhesive. Use epoxy for all glued joints unless
stated otherwise.
