The landing gear failsafe is a method of protecting your airplane from an accidental retract of
the gear while it is sitting on the ground below the setting (ex: 002: below 2 meters). If the
plane is sitting on the ground and a retract command is given, the gear will not retract. If you
want to bypass this feature, toggle the F/S off by tapping the “Manual” button, this will turn the
F/S LED red.

C-2) Long press- Holding this button down when “ PSI ” is displayed will enter the “Pressure
Loss Protection Setup”. This feature will deploy the landing gear in the event of a leak.
Increase the feature by 10PSI with each press, max. is 60PSI. Hold the “SETUP” button
down and the setting will be saved. Press the “SETUP” button and “V” will be displayed.
