CARF-Models Extra 330SC (3.1m)
General Tips:
We recommend that you follow the general order of construction shown in this manual for
the fuselage, as it makes access to everything easier and saves time in the end. The last
item to be glued in position should be the Fuel tank mounting plate, as it makes access to
the rudder tray and exhaust system less easy. The wings and stabs can be done at
almost any time, and only need servos installing anyway, as the control-surface horns are
factory-installed for you.
The first thing to do is protect the finished paint on the outside of the model from
scratches and dents during building - so cover your work table with a piece of soft carpet,
cloth or bubble-plastic. The best way to stop small spots of glue getting stuck to the
outside of the fuselage is to give the whole model 2 good coats of clear car wax first, but
of course you must be sure to remove this 100% properly before adding any additional
decals or markings. If you prefer you can cover the majority of the fuselage with the
bubble-plastic used to pack your model for shipping, fixed with paper masking tape, which
also protects it very well.
When sanding any areas of the inside of the fuselage to prepare the surface for gluing
something onto it, do NOT sand right through the layer of glasscloth on the inside foam
sandwich ! It is only necessary to rough up the surface, with 60/80 grit or equivalent, and
wipe off any dust with alcohol (or similar) before gluing to make a perfect joint.
Before starting construction it is a good idea to check inside the fuselage for any loose
glass fibres that could cut your hands, and a quick scuff over any of these with a coarse
Scotchbrite
pad will remove them.
Note: It is very important to prepare the inside of all composite parts properly, by sanding
and
cleaning the surface with de-natured alcohol or equivalent, before gluing any parts to
them.
