And very difficult to retain the same 'feel'. Typical model trannys with centering springs do not 'feel' like the full size control feedback. Models fly in the same air, so do not 'influence' the same mass of air to do the job, and have much lower inertias than full size, so need much less 'bank angle' to turn at the same rate, etc, etc, etc. The best you can do is to fly the thing with respect to the full size airplanes capabilities, and do it as smoothly as you can, almost as though you were in the cockpit...there was a spate of 'scaling' formulae a while back, but I can't help thinking it was just an excuse for various modellers inability to design/build scale models light enough to fly at scale speeds, but that is only a personal opinion, of course.
