Fit the nose leg housing
Level the aircraft laterally: a straightedge across the bottom of the front doorframes or across
the front wing attachment lugs will provide a good reference, then pack under the main
wheels as required in order to level the aircraft in the lateral or rolling plane.
Place a straightedge or ruler under the centre of the fuselage and measure up 25mm. This is
the position for the bottom of the square outer backing plate for the nose gear housing.
Centre the outer backing plate on the lower firewall and drill one top ¼” hole only and push a
bolt through, then fit up the nose gear housing and place a digital protractor or a spirit level
across the top of the white bush as shown above and carefully level the nose gear housing.
Once it is level, drill the other top hole and recheck for level then drill the bottom holes and
bolt the nose gear housing in place. You will need to flock the 2 internal braces in place at this
time – sand and clean the surfaces to be bonded then mix a small batch of flock and coat the
back of each brace then press into place and secure with 2 x AN4-16A bolts at the top and 2 x
AN4-22A bolts at the bottom and tighten the Nyloc nuts firmly.
Drill the holes for the steering links: measure out 30mm and up 40mm from the top plate and
drill a pilot hole, then use a 1¼” hole saw to drill through the firewall. Note that the predrilled
holes in the firewall may not be in the correct positions, so measure carefully as above.
Drill the top holes of the internal braces (circled at right and at above
right) from the back of the firewall and then fit the bolts from the
firewall side with 1 penny washer under the head of each bolt and a
normal washer and Nyloc nut on the inside of the firewall.
