Use a pencil to mark the position of the clamp plate on the top and bottom of the gear leg –
the clamp plate will be flocked onto the gear leg and the marks indicate where you will need
to roughen the gear leg in order to provide a key for the flock. Remove the clamp plate;
roughen the top of the plate and the marked areas on the top and bottom of the gear leg.
On each side of the floor just behind the front seats there are the mounting holes for the main
gear, and each hole will have a reinforcing plate flocked over it. (The plates are on the Card,
part numbers
6036094
and
6037094
, and can be seen the lower left-hand photo on the
previous page.)
Roughen the area around each hole and the back of each reinforcing plate to provide a key for
the flock. The surface around each hole is not flat, and no attempt should be made to make it
flat because doing so would require removal of large amounts of glass fibre from the floor
which would weaken the area.
Fit the main gear legs
Mix a batch of resin, keep a small amount aside and add flock to the remainder.
Apply a 2mm layer of flock to the top of the clamp plate and reassemble the clamp plates: fit
2 x AN6-26A bolts and washers to the clamp plate then fit the yellow clamp plate packer to
one bolt only.
Fit the assembly around the gear leg then fit the yellow clamp plate packer to the other bolt
and fit the bolts up through the holes in the fuselage.
Push the gear leg firmly up against the fuselage and use a softheaded hammer to drive the
clamp bolts and centre bolt fully home.
