Support Equipment

The following items, which are not 

included with your Saito engine, are 

necessary in order to operate the  

model engine:

1. Fuel. For maximum protection 

and longevity of its engines, Saito 

recommends a fuel containing a  

20:1 gasoline to oil ratio. We recom-

mend a synthetic based oil such as 

Evolution Oil (EVOX1001Q). High 

octane fuel is not needed for this 

engine.

2. Propeller and Fuel Consumption: 

If you are using a high load (prop 

diameter and or pitch is large), the 

air-fuel mixture needs to be richer 

than with a light load. The main 

high-speed needle will need to be 

opened even though the rpm's will 

be lower than if you were using 

a smaller propeller. Conversely 

if you are using a low load (prop 

diameter and or pitch is small), the 

air-fuel mixture needs to be leaner 

than with a heavily loaded engine. 

The main, high-speed needle will 

need to be closed, even though the 

rpm's will be higher than if you 

were using a larger propeller.  For 

the longest engine life and best fuel 

consumption, the propeller you 

choose should provide your best 

level flight speed at less than full 

throttle.  

3. Fuel Filter and Fuel Pump. 

Because commercial gasoline has 

many impurities be sure to use a 

reliable filter when refueling the 

onboard tank of the aircraft.  

CAUTION:  If a quality filter 

system is not used impurities and 

dirt will be transported to the carb, 

clogging internal filter screens and 

passages, possibly causing an engine 

failure or poor running of your engine. 

This could lead to a crash resulting in 

injury or property damage.

4. Fuel Tank.  Choose a tank with 

a capacity of 14–17 ounces (400-

500cc's). This will provide on 

average a flight time of 11 to 14 

minutes at full throttle. Make sure 

you use a gasoline-compatible fuel  

tank stopper and gasoline-

compatible fuel line both inside the  

tank and for all connections outside 

of the tank. (We recommend 

SAIG36155 for your internal and 

external fuel line) In the fuel line 

between the tank and the carburetor, 

make sure you use an inline fuel 

filter of some type (HAN143 

recommended). We also recommend 

you use SAIG36154 Filter with 

weight as your clunk inside the tank.

5. Spark Plug Wrench. An included 

spark plug wrench is used to remove 

and tighten spark plugs. 

6. Manual or Electric Starter. For 

manual starts, a heavy-duty leather 

glove is highly recommended.
