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.
