Note regarding Styrofoam wing cores

For all joints involving Styrofoam wing cores it is essential that you do not use any solvent
based adhesives, and in particular avoid use of any form of cyano-acrylate glue. Use of such
adhesives will destroy the foam and render the affected parts useless. Use only solvent-free
adhesives, such as Epoxy resin and/or Aliphatic Resin (white wood glue) if working
anywhere near exposed areas of Styrofoam.

Note regarding the use of Epoxy Resin.

Epoxy alone is not a viable adhesive! However, the addition of appropriate additives makes
for a variety of excellent adhesives. Match the choice of additive to the job at hand:
Chopped cotton fibres – produces a tough but flexible joint.
•
Superfine glass fibres - makes a hard joint.
•
• Micro-balloons – produces a highly effective, lightweight filler

Assembling your ALPINA 5001.

The kit you have purchased includes all the parts required to complete the basic airframe
(ARC) and covering (ARF), but does not include adhesives or radio control components. You
can make a significant contribution towards the ultimate appearance and performance of
your model by building carefully and accurately. It is a well known fact that a poorly built
model does not fly well and may be difficult to control. A well built and properly trimmed
model will reward the pilot and spectators with good performance and accurate handling
characteristics. Be patient, take your time; the effort will be well worth while!
Tip. Take time to read through these instructions in their entirety before commencing
the assembly as this will provide you with a better insight of all the individual steps
and how they might affect one another.
Note: For those customers intending to install an electric motor, please pay particular
attention to the parts of the instructions indicated with an asterisk (*) which indicates steps
either not required (or optional) or involve substantial differences.

The Fuselage.

Begin the construction with the Fuselage as this is the point of reference for all other parts.

Fuselage Openings

Open out all of the openings in the fuselage in the area of the wing fairing and the tail-plane.
Use a 3 mm dia. drill to make a series of small adjacent holes to prepare the openings as
indicated by the markings in the mould. Finish the openings using a small file.
Tip: Use a needle file or suitable rotary tool to finish the job.

Installing the winch hook (*)

Using a flexible tape-measure, measure and mark a point 670 mm from the nose along the
underside of the fuselage. Drill a 2.5mm hole to accommodate the winch hook. Cover the
hole on the outside with tape to protect the surface and roughen up the inside of the fuselage
