STEP 6: Engine & Cowl Installation
•
Using the 550 mm metal pushrod, trial fit the pushrod
through the firewall with the clevis at the nose wheel
end.
•
Note
that the angle of the steering arm is angled
approximately 45 degrees to the firewall to allow
movement in both directions.
•
Centre the nose wheel and mark and make a ‘Z’ bend
to complete the installation.
•
Fit the cowl mounting blocks to each corner of the fire-
wall as shown.
•
Place some masking tape along the front edge of the
fuselage and draw two lines so that they join at the
middle of the cowl mounting block.
•
Fit the cowl and hold temporarily in position with mask-
ing tape. Also place some masking tape of the rear
edge of the cowl.
•
Using a straight edge, continue the lines from the
masking tape on the fuselage onto the cowl and drill a
5 mm hole where the lines intersect.
•
With the cowl in place, measure the distance from the
front of the firewall to the front of the cowl. (approx
150mm)
•
Note
that if you are using a large glow engine, the
included engine mounts can be used. Install the
engine on to the engine mounts using this measure-
ment as a reference. Allow a few extra millimeters for
clearance between the spinner back plate and the
cowl.
•
Note
that If using a gasoline engine, stand-offs or
spacers may be required to get the correct distance
out from the firewall.
•
Measure and draw reference lines on the centre of the
firewall as shown.
•
Centre the engine on its mounts or stand offs, which
ever is applicable, and drill the holes for the mounting
bolts.
•
Also drill a hole for the throttle pushrod to exit the
firewall.
