Phantom FX-61 mixer
===================
This file defines mixers suitable for controlling a delta wing aircraft using
PX4/Pixhawk. The configuration assumes the elevon servos are connected to
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 are set so that pitch will have more travel than roll.

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.
