A switch changed QuadPlane assistance

What ArduPilot says:

• QAssist: Force enabled
• QAssist: Disabled
• QFwdThr: …
• QAssist: Enabled

On a QuadPlane, Q assist is the lift motors starting by themselves in fixed-wing flight when the plane gets too slow, too low or tips too far. The three-position switch RCn_OPTION 82 sets it: low “QAssist: Disabled” (the lift motors never help), middle “QAssist: Enabled” (they help when the assist limits are crossed), high “QAssist: Force enabled” (they run all the time). “QFwdThr: ON” or “OFF” comes from another switch (RCn_OPTION 176): it forces the forward motor, rather than tilting the whole aircraft, to be used for moving forward in VTOL modes (see Q_FWD_THR_USE), or stops forcing it.

With “QAssist: Disabled” a QuadPlane that stalls in fixed-wing flight gets no help from its lift motors. Know where the switch is before take-off.
