Tips & Notes

SkyMAXX is a sturdy trainer for 3 channel RC with a scale-like apperance. Take-off is easy with its
tricycle undercarriage and big wheels from any flying field with short grass.
All parts, with the exception of stripwood, are precisely laser-cut and allow for a rapid building
process. The wing uses the aero-naut building jig for precision and easy building – a great
feature for beginners and less advanced modelleres.
We use mainly light-ply and balsa for the SkyMAXX which results in a light yet strong model with
the flying characteristics of a trainer.
Most wood parts in the kit are laser-cut and numbered. Stripwood can be easily identified by
means of the parts list at the end of the manual. Um die Laserteile aus den Materialträgern zu
lösen, durchtrennen Sie die Stege, von denen die Laserteile im Materialträger gehalten werden,
mit einem scharfen Balsamesser. Säubern Sie anschließend die dunklen Kanten der Laserteile mit
Schleifpapier, um die Reste der Stege zu entfernen, eine gute Verklebung der Bauteile und nicht
zuletzt eine gute Optik des Modells zu erzielen.
Prüfen Sie alle Bauteile vor dem Verkleben auf richtigen Sitz und arbeiten Sie die Teile ggf. etwas
nach. Achten Sie darauf, dass alle Verklebungen vollständig getrocknet sind, bevor Sie mit dem
nächsten Bauschritt beginnen.
Der Zusammenbau des Modells sollte in der Reihenfolge der Baustufen nach dieser Anleitung
erfolgen. Lösen Sie immer nur die Teile aus dem Materialträger, die Sie für den aktuellen
Bauschritt benötigen.
Als Klebstoff empfehlen wir, soweit nicht anders vermerkt, einen schnell aushärtenden Weißleim,
der hohe Festigkeit bei geringem Gewicht bietet. Der Klebstoff besitzt auch nach dem Aushärten
eine gewisse Elastizität und ist der ideale Klebstoff für die im Flug auftretenden Belastungen.
For building we recommend our
aero-pick modeller‘s pins

Please note recommended glues.
Attention! Read instructions
carefully
Note! Additional information for
current building step
Carefully sand off small tabs that
hold wood parts in place to
achieve good results.
Use a sharp modelling knife to cut
individual parts from laser sheets.
Do not brake out to avoid
damage!

Note: Graphics show electric version.
IC Power: Before you glue former V-2 in place, drill holes for motor mount,
throttle control linkage and fuel line. The crankshaft position is indicated on the
former. If motor mount provides notches for nose wheel gear, holes for included
plastic nose gear bracket do not apply.
Glue in place former E-2 (electric power) or V-2 (IC power).
Carefully pull together fueselage sides and glue in place formers E-1A/E-1B (electric
power) or formers V-1 (IC power). Secure with clamps. Use scrap wood to avoid damage
to fuselage sides!
Carefully sand top and bottom of formers flsuh with fuselage sides.
Cut off triangular stock flush with front of formers and sand.
In the following building step use E-3 for electric power and V-3 for IC power.
Carefully bevel curve at rear of E-3 and V-3 to the front and to the bottom. This is
where the front cockpit glazing will be inserted in the slot between instrument
panel and E-3/V-3. Glue E-3/V-3 in place and secure with tape.
Glue in place part R-24 and R-25 on the uderside of the fuselage and secure with
tape.
Depending on selected motor and prop adaptor E-4/V-4 can be glued to the nose
to minimize the gap between front former and spinner.
Additionally, E-4/V-4 can be used to indicate the correct outline of the nose
before you round off the edges.
