2.3.1 Transmitter Antenna
Precautions:
□
For best signal quality, make sure that the antenna is at about a 90 degree angle to the model. Do not
point the antenna directly at the receiver.
□
Never grip the transmitter antenna when operating a model. It significantly degrades the RF signal
quality and strength and may cause loss of control.
2.3.2 Wheel and Trigger
The FS-iT4S has two main control inputs, the wheel and trigger.
□
Wheel: Steering, use to control the direction of the model.
□
Trigger: Used for acceleration, breaking and reverse.
