+Aileron/rudder/elevator/throttle/wheel mixer for PX4FMU
+=======================================================
+
+This file defines mixers suitable for controlling a fixed wing aircraft with
+aileron, rudder, elevator, throttle and steerable wheel controls using PX4FMU.
+The configuration assumes the aileron servo(s) are connected to PX4FMU servo
+output 0, the elevator to output 1, the rudder to output 2, the throttle
+to output 3 and the wheel to output 4.
+
+Inputs to the mixer come from channel group 0 (vehicle attitude), channels 0
+(roll), 1 (pitch), 2 (yaw) and 3 (thrust).
+
+Aileron mixer
+-------------
+Two scalers total (output, roll).
+
+This mixer assumes that the aileron servos are set up correctly mechanically;
+depending on the actual configuration it may be necessary to reverse the scaling
+factors (to reverse the servo movement) and adjust the offset, scaling and
+endpoints to suit.
+
+As there is only one output, if using two servos adjustments to compensate for
+differences between the servos must be made mechanically.  To obtain the correct
+motion using a Y  cable, the servos can be positioned reversed from one another.

+Elevator mixer
+------------
+Two scalers total (output, roll).
+
+This mixer assumes that the elevator servo is set up correctly mechanically;
+depending on the actual configuration it may be necessary to reverse the scaling
+factors (to reverse the servo movement) and adjust the offset, scaling and

+Rudder mixer
+------------
+Two scalers total (output, yaw).
+
+This mixer assumes that the rudder servo is set up correctly mechanically;
+depending on the actual configuration it may be necessary to reverse the scaling

+
+Motor speed mixer
+-----------------
+Two scalers total (output, thrust).
+
+This mixer generates a full-range output (-1 to 1) from an input in the (0 - 1)
+range.  Inputs below zero are treated as zero.

+depending on the actual configuration it may be necessary to reverse the scaling
