FMA Co-Pilot questions

Now that the ArduPilot is available, I have a few questions about using the FMA co-pilot.1. Is it really necessary to have the proportional aux channel on a TX? Alternatively, the trim can be set on the FMA computer. I imagine that having it on the TX makes in flight trimming possible, but that it is possible by trying different trim scenarios between flights and using an on/off aux switch.2. Can the autopilot enable and the FMA copilot enable be switched off the same channel on the RX with a Y-harness? It seems that if the co-pilot is operating with an on-off switch, this would allow for simpler switching between manual and autonomous modes.3. Can the co-pilot be used with the rudder channel on an Easy Star with the ArduPilot? The co-pilot would receive input from the Ardupilot, which would either be autonomous or manually commanded. The co-pilot trim would be set to increase the stability with applied rudder. This would significantly decrease the turning capability (wider turns), but would allow for 3 channels to be used. I think it would be desirable to have separate enable switches for the ArduPilot and CoPilot if this scenario is possible.Thanks,Pat

    1) No. You can use a toggle switch and set the gain on the ground with the dial on the Co-Pilot or no use switch at all (FMA on all the time). It's just easier to tune the aircraft with the proportional dial on your Tx.

    2) Yes, but again see 1 for the advantages of a separate proportional dial for the Co-Pilot.

    3) Possibly. We haven't tried.
