I am sure there are exceptions, but, most ''ccomputer'' transmitters with at least 6 channels have flaperon mixing.
In a mode one system, throttle and aileron are controlled with the right stick. Flaperons are activated with a switch or knob and turning it on moves both ailerons down (or up) a certain percentage of the total available travel. Moving the aileron stick still moves the ailerons normally but the amount they can move is limited because part of the travel has already been used.
In ''normal'' operation, moving the elevator stick does NOT cause flap or aileron to move. DR1's example is a specific mix that probably is activated by a switch and used to make really tight loops.
What he said..."Normal" flaperons are operated by a rotating knob on the transmitter (the flap control) and are independent of other controls. Our case was special use. One aileron servo is plugged into the aileron channel and the other is plugged into the flap channel, then you mix the two. Getting the directions and percentages of movement can be a little bit of a bear to get set up right.
