Aero-Maxx
Aero-Maxx building instructions
2
The “Aero-Maxx” is a compact electric glider of all-wood construction, produced using modern CNC
technology. For ease of transport the wing is in two panels, joined by two steel rods for flying. The individual
model components are so accurately manufactured that everything fits perfectly. Very little building work is
required to complete the aeroplane.

2.) Inboard wing panels with factory-fitted joiner tubes, balsa / spruce construction, ready-built bare
structure
3.) Outboard wing panels, balsa spruce construction, ready-built bare structure
4.) Tailplane and elevators, balsa construction, ready-built bare structure
5.) Fin and rudder, balsa construction, ready-built bare structure
6.) Machined balsa tailskid, ready to fit

The wing
• The wings are of classic built-up construction, and each wing panel consists of two parts. The two panels
should be glued together at the angle dictated by the facing ribs.
• Lay the inboard wing panels (with the built-in joiner tubes) flat on the building board and pin them down.
Slip a piece of clear plastic film under the outer ribs, to prevent the panels becoming glued to the building
board.
• Apply a thin coat of epoxy to the joint surface of the outboard wing panels, then push them against the
inboard panels and clamp the facing ribs together using clothes pegs. Check that the outboard panels are
not twisted relative to the inboard ones: the rib outlines must line up exactly. Carefully wipe away excess
epoxy which is squeezed out of the top of the joints.
• Allow the adhesive to cure fully (!), then remove the joined wing panels from the building board and slice
off any excess adhesive using a sharp knife.
• Carefully sand the joint areas smooth and flush.
The fuselage
• The basic fuselage structure is supplied ready-made; all you have to do is glue the tailplane and fin to it.
• Remove the elevators from the tailplane and place them to one side for the moment.
• Carefully slide the tailplane through the slot in the fuselage from one side. If it is too tight a fit, open up the
slot slightly using fine abrasive paper.
• Set the tailplane exactly central. Sight along the fuselage from the nose to check that the tailplane is
exactly horizontal. Take your time over this; it is better to check twice to be really sure.
• When you are satisfied, glue the tailplane to the fuselage using thin cyano-acrylate: apply small drops of
the adhesive to the joint areas of the fuselage, and allow them to run along the joints. Ensure that the cyano
really does run into all the contact areas.
