Flight Modes

Altitude Hold

Holds altitude, and self-levels the roll & pitch axes.

In Altitude Hold mode, roll, pitch, and yaw operate the same as in Stabilized mode. The X55 maintains a consistent altitude, If the throttle stick is in the middle (40% ~ 60%) the X55 will maintain the current altitude. The X55 will descend or climb depending on the deflection of the stick.

Loiter

Holds altitude and position and uses GPS for movements

Loiter Mode automatically attempts to maintain the current location, heading, and altitude. The pilot may fly the X55 in Loiter mode as if it were in a more manual flight mode but when the sticks are released, the X55 will slow to a stop and hold the position.

Loiter flight mode requires GPS fix. Please make sure there are at least 12 satellite connections. Please do not use this flight mode when operating under conditions where there’s a higher risk of GPS signal loss.

Auto

Executes a pre-defined mission.

In Auto mode, the X55 will follow a pre-programmed mission stored in the autopilot which is made up of navigation commands.

Although this flight mode supports auto take-off and landing, it is highly recommended that the pilot perform manual takeoff and landing. The X55 also requires a good GPS lock before takeoff to set a valid home position.

Return to Launch (RTL)

Returns above the takeoff location, may also include landing.

RTL mode navigates the X55 from its current position to hover above the home position. By default, X55 will execute the landing command once above the home position. The behavior of RTL mode can be controlled by several adjustable parameters.

RTL triggered by failsafe will override all other flight modes. The pilot can regain control of the X55 by pressing the desired flight mode button.
