Default FMA Co-Pilot plane application Y ail output?

Can some ACTUAL USERS assist please.

As the unit has only a single A input and output put terminals,
1) will the unit work using a Y-harness on the output side?

2) If it will work on aerobat type plane 2A servos and 2F servo, what program modes are not possible?

I guess relying on the end-users for assistance is the best method, the manuf. is happy to take your orders but Mr. Marks must have been out of office since I sent an e-mail for assistance.

Quotes from FMA printed data:
At this time, Copilot does not have the cables and connections needed to operate dual ailerons (for use as
flaperons) or CCPM heli controls that require three servos with mixing in the transmitter.
The current CoPilot does not handle CCPM helicopters or aircraft configurations that include differential ailerons or flapperons. The CoPilot will only operate in aircraft that use one servo for pitch and one servo for roll controls.
3) Futaba defines:
Aileron Differential Creating larger upward aileron travel than downward aileron travel to help minimize the model "dragging" the drooped aileron which causes a model to yaw with aileron input

I haven't actually used the co-pilot, but since no-one else has replied yet, here's my theoretical answer.

The co-pilot only controls one channel per axis, so it should work if you connect the Y-cable to the aileron output of the co-pilot. Make sure that the aileron servos are setup to move the right way. I don't think it would be advisable to hook up flaps to the co-pilot. It is meant to control roll (aileron/rudder) and pitch (elevator). Mixing should work the same as if you had setup your plane with only one servo per axis.

You can achieve manual aileron differential by adjusting where the aileron connects to the servo arm's arc, so that you have slightly more upward movement than down.
