The lift-motor layout in Q_FRAME_CLASS is not supported

What ArduPilot says:

• Config Error: Unsupported Q_FRAME_CLASS N

At start-up the QuadPlane code found a Q_FRAME_CLASS it cannot build a motor mixer for; the number in the message is the value it found. It accepts 1 (quad), 2 (hexa), 3 (octa), 4 (octaquad), 5 (Y6), 7 (tri), 10 (tailsitter with one or two motors), 14 (deca) and 15 or 17 (layouts from a Lua script). This is a “Config Error”: it repeats every 5 s and the board does nothing else until the value is corrected and the board rebooted; parameters can still be changed.

What to do, most likely first

1. Q_FRAME_CLASS is 0 (undefined).

   FixSet Q_FRAME_CLASS to the real layout of the lift motors and Q_FRAME_TYPE to their arrangement (1 is X), then reboot.

2. The value is one the parameter list offers but the QuadPlane code does not take, such as 12 (DodecaHexa), or a class copied from a copter.

   CheckCompare the number in the message with the list above.

   FixChoose a supported class and reboot.
