The photographs above clarify the method of fitting the wheels: on the left the wheel
spat and a cross-section through the wheel, on the right the system minus the wheel.
Once the wheels and spats are fitted, the undercarriage legs can be attached to the
fuselage using the retaining screws provided. Apply a drop of UHU thread-lock fluid
to all the screws to prevent them working loose.
Installing the glowplug engine and silencer
This section describes the installation of the OS MAX 46 AX only.
Place the engine on the mount with both mounting lugs seated squarely on the
mount arms. The distance between the firewall and the front face of the propeller
driver should be 113 mm. You can now mark the position of the holes for the engine
mount on the firewall.
Drill 2 mm Ø pilot-holes for the engine retaining screws (2.4 mm Ø pan-head self-
tappers). Connect the throttle pushrod to the carburettor arm and slip it into the
plastic guide tube. Now fix the engine to the mount from above using the screws
mentioned earlier. Connect the Z-bend of the throttle pushrod to the outermost hole
in the carburettor throttle arm. Slip the plastic guide tube onto the throttle pushrod,
then fit the pushrod through the hole in the firewall, slipping the plain end of the rod
through the cross-hole in the swivel pushrod connector.
