Oil return
■ CAUTION:
The engine design is for a conventional, non-aerobatic, fixed
wing tractor or pusher type configuration with the oil return
port in the optimum position. With this consideration the
engine is properly lubricated in all flight profiles. Aircraft that
are not conventional (e.g. airship, gyrocopters, dive brake
equipped aircraft etc.) that require engine load in steeply
incline and decline angles (see also sec. 8.1, point 12) may
require special lubrication considerations.
According to propeller configuration choose the appropriate connection for the
oil return line.
Position 1 for tractor or 2 for pusher configuration. See Fig. 40.
