Building The Base Plate And Landing Gear - GRAUPNER Agusta A119 Handbuch

Assembly
Preparing the chassis
We assume that you have already test-flown your MICRO STAR 400 and set it up correctly.
This is important, as access to the components for adjustment and maintenance is greatly
restricted when the mechanics are inside the fuselage.
• • • •
Remove the canopy (no longer required).
•
Remove the flight battery.
•
Unscrew the stabiliser panels from the mounting flanges.
•
Locate the self-tapping screws which retain the tail boom braces and unscrew them from the
flange on the tail boom. Rotate the flange through 180° on the tail boom, so that the
stabiliser mounting is on the underside, then re-fit the screws to secure the boom braces
again.
•
Remove the speed controller from the underside of the chassis (it is re-installed later).
•
Unscrew the tail rotor bellcrank and disconnect it from the pushrod.
•
Loosen the clamping screws in the tail rotor housing, and withdraw the tail rotor housing to
the rear.
• • • •
Separate the skid landing gear (no longer required) from the chassis by undoing the four
retaining screws. The screws are re-used.

Building the base plate and landing gear

The first step is to insert the two lateral stiffeners in both sides of the base plate, and fix them in
place using cyano-acrylate adhesive ("cyano"). This is the procedure: lay the plate down flat and
glue the stiffeners to the rear of the plate only. Allow the glue to set hard, then pack up the rear
end by about 6 mm and glue the stiffeners to the front of the base plate, so that the plate takes
up the same angle as the stiffeners.
Glue the balsa in-fill piece to the underside of the base plate, flush with the rear edge. When the
glue is dry, continue the circular opening in the base plate through the balsa. Round off the
outside edges of the balsa in-fill piece as shown, using abrasive paper.
