Many models do this, particularly soarers. Fast aerobatic models do, though only Matts Arrow comes immediately to mind. Keep the pivot forward of 25% MAC, gear the movement down to not much to start with, depending on the speed you expect to fly, of course. The fixed tail/elevator deal is much easier for beginners, and probably just as efficient, if not more so. But feel free to experiment.
