The QuadPlane code started, with this motor layout

InformationPlane: take-off, landing, QuadPlanePlane only

What ArduPilot says:

Sent once when the VTOL code has started; the same text is written at the top of every log. After “Frame:” comes the lift-motor layout ArduPilot built from Q_FRAME_CLASS and Q_FRAME_TYPE, for example QUAD/X. Check that it is your layout: with the wrong one the aircraft flips over at take-off.
