Installation Guide:

Make sure that your plane has good status before installing GR7SF and other electrical device on it.

The receiver need to be firmly mounted near the gravity of the plane by double side tape, refer to illustration below.

Ensure the axis direction is out of four kind types description below. Fixed GR7SF reference the information mentioned in axis description pictures on receiver’s box.

Turn on S-FHSS transmitter, turn off any mixer feature on the transmitter, firstly set stick trimming and sub-trim parameters to zero .Preset all sensitivity at about 40~60%, Select the proper mode of mixer on GR7SF and power on it, check and adjust aileron, elevator or rudder to the neutral position of control surface. Adjustment can be done by stick trimming on the transmitter. If mode selection and sensitivity changed, please power the GR7SF again to let new feature take effect.

Check all servo controlling that you need under flying is correct. Reverse the servo direction on the transmitter if need. Roll the model along the x, y or z axis alone to check the compensation direction that you want as the picture show.

If compensation direction is reversed, set the sensitivity value reverse. If any sensitivity changed, please power the GR7SF again to let new feature take effect.

Fail-safe setting:

GR7SF set failsafe on the S-FHSS transmitter just like the operation of the FUTABA receivers.

We highly recommend you set failsafe feature while flying your models. An example of a useful Failsafe setting would be to shut down the model’s throttle, so that it does not fly or drive away uncontrolled.
