PRECAUTIONS may also move to the extent while the model is being carried out to the ﬂight line. Before take off, you must visually center the tail rotor pitch slider and level the swash plate by using the transmitter control sticks. You can also center the servos by moving the tail rotor stick full left, then full right, back to full left and then allow the stick to center within one second; the same method applies for aileron and elevator servos.

The one setting applies to both roll and pitch axes; they are not individually adjusted. Use the Data [+] or [-] key to make an adjustment. The [SWS.Rate] is dependent on servo arm length and head geometry, so it will be necessary to use a pitch gauge to make adjustments.

The display shows “!” when the stick is at the saved point. The zero degrees pitch setting must saved into the CGY750 for F/F mixing and/or linkage compensation to function correctly.

TUNING GUIDELINES FOR CGY 750 * When the CGY750 is used with a ESC or BEC and a power switch is not used there is a possibility that the intermittent connection as you connect the ﬂight battery may cause the CGY750 initialization to fail. Always ensure that the gyro has initialized properly by verifying that the gyros are compensating as the helicopter is moved. It is recommended to use a power switch on the power supply line to avoid this possibility.
