All other lines are ignored. + +This delta-wing mixer assumes the elevon servos are connected to PX4FMU servo +outputs 0 and 1 and the motor speed control to output 2. Output 3 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. + +M: 3 +S: 0 0 10000 10000 0 -10000 10000 +S: 0 0 3000 5000 0 -10000 10000 +S: 0 1 5000 5000 0 -10000 10000 + +M: 3 +S: 0 0 10000 10000 0 -10000 10000 +S: 0 0 5000 3000 0 -10000 10000 +S: 0 1 -5000 -5000 0 -10000 10000 + + +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.
