Note:
Areas of the fuselage which are to be glued should be rubbed down with fine-grit
abrasive paper to remove any 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
manufacturer. The main Graupner FS catalogue includes many other types of glue.
Ensure good ventilation in your workroom when using solvent-based adhesives.
Read the manufacturer’s instructions.
Important note
It is essential to avoid using solvent-based glues for any joint in which the
adhesive comes into contact with the styrofoam wing core. This applies in
particular to cyano-acrylates, as these materials immediately attack the foam
and cause large-scale damage; in most cases the component is rendered
unusable. Use only solvent-free adhesives; we recommend UHU-Endfest (24-
hour epoxy resin) or epoxy laminating resin thickened with chopped cotton
strands. Do not use 5-minute epoxy for joints which are vital to airframe
integrity, or for crucial control linkages!
Note regarding: “gluing with epoxy”
Epoxy laminating resin is not an effective adhesive on its own! These resins only
work well as glues when thickened with various additives. You can adjust the
qualities of your adhesive by choosing the appropriate additive to suit your
application:
1. Chopped cotton strands produce a tough, flexible joint.
2. Super-fine glass fibres produce a rock-solid joint which is easy to sand.
3.
Micro-balloons transform epoxy resin into a lightweight filler paste.
Radio control system
We particularly recommend: mx-12 to mc-24 computer systems
