User Manual

PEPPER is a sleek model with a considerable speed range. Building materials are mostly laser-cut balsa and light-ply to achieve a light yet strong
structure, spruce is used to enhance the strength of the wing spars. For electric power choose a 28 mm brushless motor with a power of about 200 W. They
all have a bolt circle diameter of 19/16 which will fit the model´s motor mount.
Construction should be according to the step-by-step instructions provided in this manual. Use the parts
list to identify the included stripwood and hardware. Always check that parts fit perfectly and correct, if
necessary, before you glue. Give glue sufficient time to dry or cure, before you proceed to the next step.
We recommend white glue (if not otherwise noted) for gluing, which offers good strength and low weight.
White glue retains a certain degree of elasticity after the glue has cured and will stand up to any loads
which occur during flying.

In a first step glue together main spar parts F1 A and F1 B. Use a
straight edge against the spar´s building tabs for proper alignment
and secure with tape.
Assemble the 4-part wing jig, place on a flat building board and
secure with tape.
Insert main spar in wing jig. Glue together centre ribs F2, then
glue ribs F2 to F14 to main spar as shown. Make sure that ribs are
fully seated in main spar and jig.
