I have seen an arrangement on some European microlights with center stick in which a single throttle cable is controlled by a torque tube behind the panel controlled by levers at either end of the panel. Here is a Best Off Sky Ranger with that arrangement including the factory-stock knobs that look like golf balls because...they are golf balls!
