Another example is to setup the left and right engine on the left and right side lever controls. Add 2 P mixes to each. The first Pmix mixes the channel to itself (-100%/-100%) to cancel out the lever input. Leave the offset at zero, Include and Origin off, Trim on. This parks the servo at center. Use the second Pmix to slave to the throttle stick. Assign all 4 Pmixers to the mix switch. Result is Mix switch on, both channels respond to the throttle stick only, moving side levers has no effect. Mix switch off, both channels work by their respective side levers and the throttle stick has no effect. The Pmixes for each channel could be assigned to separate switches, so control could be transferred individually.

This example illustrates why lots of channels, lots of Pmixers, and unlimited switch assignment flexibility, are is so important for building scale features. Other nice features are differential throttling via the rudder – requires 2 more Pmixes and another independent switch, 4 Pmixers if you want it to work at high and low throttle. A 4 engine plane would need 4 more Pmixes and 2 more independent switches. I lke to put my nose or tail wheel steering on a separate channel then slave to the rudder. This way I can change trim of each without disturbing the other and shut off the wheel steering when the gear is retracted eliminating the need for linkage that can handle the steering movement gear up. Also like to have 2 rates on just the wheel, very high for taxi and low for takeoff and landing. So wa are talking 2 more Pmixes and another independent switch. I like to use the multipoint throttle curve to program a small dead band at the bottom of the throttle stick movement. Then go into the transmitter and modify the spring return to apply pressure just above the dead band. So throttle works normally from full to idle but there is a little bit more movement against the spring for activating air or wheel breaks.

The possibilities go on and on. The limitation of the current generation of radios available are still quite large. Basically they are just getting capable of doing these things. Problem is they can't do more than about one or 2 of them together. Bummer.
