rapidly. The fuel mixture may be
too lean when the engine stops
when the throttle is rapidly
opened from idle. Attempt to cor-
rect this by rotating the idle nee-
dle valve counterclockwise 1/4 to
1/2 turn at a time until the engine
transitions smoothly without hesi-
tation upon opening the throttle
rapidly. If the situation is not rec-
tified by counterclockwise rota-
tions of the idle needle valve, try
turning the idle needle valve
clockwise in 1/4 to 1/2 turn incre-
ments.

3. After obtaining the proper idle
setting, the low rpm setting can be
made through the positioning of
the throttle adjustment screw, if
applicable. If not, adjust the idle
setting via the throttle trim of
your transmitter.

If break-in was accomplished on a
test bench, your engine is ready to
be mounted to the aircraft and
flown. The initial flight should be
performed with the engine adjust-
ed for a rich fuel mixture.
1. Your Saito engine should be
securely mounted to the aircraft

using the motor mount and hard-
ware kit provided. Soft mounting
of the Saito multi-cylinder
engines is not necessary due to
the extremely low vibration
level of these engines. Please
refer to Step 12 in the “Starting
the Engine” section for the proper
mounting procedure.
2. General operating procedures
which ensure long engine life are:

Do NOT operate the engine with

a ”lean” mixture.

• 

When installing the mufflers, oil

both the manifold threads and the
engine cylinder heads. Optional
flexible mufflers are available for
the FA-170R3D and FA-450R3D,
connection for flexible mufflers is
shown in figure below. Please
refer to the Cross Reference Chart
for the part numbers for flexible
mufflers.
