+Aileron/v-tail/throttle/wheel/flaps mixer for PX4FMU
+=======================================================
+
+This file defines mixers suitable for controlling a fixed wing aircraft with
+aileron, v-tail (rudder, elevator), throttle, steerable wheel and flaps
+using PX4FMU.
+The configuration assumes the aileron servos are connected to PX4FMU servo
+output 0 and 1, the tail servos to output 2 and 3, the throttle
+to output 4, the wheel to output 5 and the flaps to output 6 and 7.
+
+Inputs to the mixer come from channel group 0 (vehicle attitude), channels 0
+(roll), 1 (pitch), 2 (yaw) and 3 (thrust) 4 (flaps) 6 (flaperon).
+
+Aileron mixer (roll + flaperon)
+---------------------------------
+
+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.

+V-tail mixers
+-------------
+Three scalers total (output, roll, pitch).
+
+On the assumption that the two tail servos are physically reversed, the pitch
+input is inverted between the two servos.

+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.

+
+Wheel mixer
+------------
+Two scalers total (output, yaw).
+
+This mixer assumes that the wheel 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
