With a displacement of 121.6 cm3, the FG-120TS is currently the most powerful engine in the Saito range, and is ideally suited to aerobatic models in the 70cc class, as well as ladder and semi- ladder models in the 70-100cc class.
As air screws, the 2-blade screws can be used in the 27x12" to 28x12" range. The speed range is between 1000 and 6000 rpm. With a FALCON 27x12", the engine reaches a maximum speed of 5000 rpm.
The fuel mixture should initially be 15:1, and can be changed to 20:1 once the running-in phase is over. SAITO recommends using PowerModel 2T-S" Deluxe Materials motor oil.
For ignition operation, a battery of over 1500mAh with a voltage range of 6-12V is required.
