Dual mixer module for deltas, flying wings and V-tail models. The V-mix module is used at the receiving system, and couples two servo functions in such a way that they can deflect in the same direction and opposite directions, e.g. elevator and rudder servos in a V-tail model, or elevator / aileron servos in a delta or flying wing. The module can also be used to couple two aileron servos which can then be operated by a further function to act as flaperons, e.g. as a landing brake.
