Give him a few swigs of some Canadian Mist. It will knock the edge off of the shakes. It works for me when I shoot my rifles in competition. Steady as a rock. Just don't get carried away as your mileage may vary with a fast craft. I have a touch of a nervous condition myself and the key is not to indulge. Anyway, best of luck with your endeaver. The best recommendation I heard was using the exponential of the radio.
