Stay on the line

Track accuracy is a whole number of metres, from 0 to 10. The demo starts at 0. The hint says it pulls the plane back onto the line between waypoints, and that 0 turns that pull off. Any other value on this field turns the pull on. The picture uses that rule: at 0 the plane sits off the line, and from 1 m upward it sits on the path.

Steepest correction angle is 30 to 80 degrees, and the demo starts at 60. It is the steepest angle the correction toward the line is allowed to use. It is not the cruise turn rate on the Fixed-wing flight card, and it is not a bank limit from the Navigation tab.

The picture is the demo rule, not a plot of the firmware curve. Moving accuracy does not write the board. Saving the field does that in the configurator.

Smooth waypoint turns has three choices, and the demo starts on Off. Off draws the path through the waypoint, with a sharp corner on the point. On rounds that same corner, and the path still reaches the point.

On, cut corners is the one the hint describes: Cut turns early, inside the waypoint. The path leaves the line before the point and never reaches it. The picture shows that as a bend that stays inside the dot.

Place the waypoints on the Mission tab. This card only changes how the plane flies the line and the corner that are already in the plan. A jump, a hold and a land action are mission settings, not fields on this card.

Off is the right starting choice when you want to see the plane arrive at the point. Use On when a sharp corner is tossing the wing. Use On, cut corners when the point sits on a tree line or a boundary and the plane should turn before it gets there. The picture on this page follows those three shapes, and it does not change the mission.

Motor off while soaring starts off. Turn it on when a soar should stop the motor. Leave it off when the motor should keep running. The switch has no extra hint on the card.

Soaring pitch freedom is 0 to 15 degrees, and the demo starts at 5. The hint says it is the pitch range the plane may wander while riding lift. At 0 that range is closed. It is not the glide pitch on the Autoland card, which is the nose angle for the landing.

The card is drawn when the board has at least one of track accuracy, smooth waypoint turns, or motor off while soaring.

Open Advanced nav on an INAV plane and find Path tracking and soaring. Chrome or Edge connects over USB or Bluetooth. Android adds Wi-Fi. iPhone uses Bluetooth or Wi-Fi and has no USB host.

Leave the prop clear of hands while you only change numbers. The first check of a new corner is still a flight, with room to go around if the turn starts earlier than you expected.
