Check that the radio control system works correctly and at full range before every flight:
switch on the transmitter and the receiving system, and extend the transmitter aerial to its
full length; walk away from the model, and check that all the control surfaces work
smoothly and immediately at an appropriate distance; check also that they deflect in the
correct "sense" in relation to the stick movements.
If you are a relative beginner to this type of model flying, we recommend that you enlist an
experienced model pilot to help you check and test-fly the model.
Care and maintenance
• Clean the model carefully after every session. The model and RC components should
only be cleaned using suitable cleaning agents. Ask your model shop for information.
Notes on building the model
Before you start assembling the model, it is important that you study the plan and read the
instructions right through to the end. Tools can be dangerous; be aware of the hazards
involved in using them.
Before making any glued joints, clean the surfaces and remove all traces of grease. We
recommend sanding lightly, or wiping with a non-greasy cleaning agent. The same applies
to surfaces to be painted, otherwise the paint is unlikely to adhere well. Before gluing parts
to the fuselage it is essential to roughen the surfaces with fine abrasive paper, and de-
grease them by wiping with acetone or similar solvent, otherwise you will not obtain strong,
durable joints. This applies in particular to moulded GRP fuselages.
Tools required to build the DIAMANT
Pencil (HB lead), felt-tip pen, setsquare, tape measure or metre rule, household scissors,
sharp narrow-bladed knife, e.g. balsa knife, Order No. 956, small electric drill, set of twist
drills, allen key, e.g. Order No. 806.
Gluing different materials
The following table gives examples of some typical joints, but it makes no claim to be
comprehensive.
Material
GRP to
plywood
GRP to
aluminium
High-density foam
to plastic
Note:
Areas of the fuselage which are to be glued should be rubbed down with fine-grit
glasspaper to remove any lingering traces of mould release agent. Carefully remove all
sanding dust. Aim at reducing the glossy surface to a matt finish, otherwise there is no
chance of a durable glued joint between the fuselage and other parts.
When using adhesives it is important to observe the instructions supplied by the glue
manufacturer. The main Graupner FS catalogue includes many other types of adhesive.
