Wing; Main Landing Gear And Gear Door Installation - Carf-Models SIAI Marchetti SF-260 Construction Manual

CARF-Models
Before starting construction it is a good idea to check inside the fuselage for any loose glass
fibres that could cut your hands. A quick scuff over any of these with a coarse Scotchbrite
pad will remove them.
Note: It is very important to prepare the inside of the fuselage properly, by roughing up and
cleaning the surface, before gluing any parts to it!
Are you ready? Then let´s start to built your SIAI Marchetti SF-260!
The following steps will describe, where necessary, primarily cutout and installation
procedures. Please refer to the Parts List for the correct sizes of the required screws,
bolts, ball-links, threaded rods, and tubing (included with kit).

1. WING

1.1 Main Landing Gear and Gear Door installation

Tip:
Before installing the gear, the wing MUST be mounted to the fuselage. This assures that the
wheels will fit perfectly within the wheel-wells in the fuselage during the retract/extension
cycle. At this stage, the fuselage has nothing inside, other than the factory installed formers,
so that it can be turned on its back to make mounting the wing easier.
For those with less room in the workshop, the steps for the wing/gear installation can be
done one side at a time. Servo and (optional) lighting installation can be carried out with the
wing panels detached.
We recommend beginning by gluing the reinforcement strips for the gear-door mounting
points. This CAN be done after the landing gear is installed, but...

Rough up the inner gluing surface, cut a 3mm
strip to size (90 x 15 mm) and glue into position
with thickened 30 minute epoxy. Use clamps to
secure till cured.
Before installing the CARF landing gear, make
sure that ALL parts are mounted (gear main
body, leg, wheel and - if used - brake system).
