+Viper Delta-wing mixer
+=================================
+
+Designed for Viper.
+
+TODO (sjwilks): Add mixers for flaps.
+
+This file defines mixers suitable for controlling a delta wing aircraft using
+PX4FMU. The configuration assumes the elevon servos are connected to PX4FMU
+servo outputs 0 and 1 and the motor speed control to output 3. Output 2 is
+assumed to be unused.
+
+Inputs to the mixer come from channel group 0 (vehicle attitude), channels 0
+(roll), 1 (pitch) and 3 (thrust).
+
+See the README for more information on the scaler format.
+
+Elevon mixers
+-------------
+Three scalers total (output, roll, pitch).
+
+On the assumption that the two elevon servos are physically reversed, the pitch
+input is inverted between the two servos.
+
+The scaling factor for roll inputs is adjusted to implement differential travel
+for the elevons.

+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.
