Oh dear.......a few replies no doubt meant in jest, or fuelled by Christmas port, but like the old crusty types who could not actually teach but just gruffly snapped if we were doing something wrong. Come on guys, you're better than that !
I only flew the '73 (Classic), for one season, it is a very poorly designed aircraft from the pilot interface point of view. I had no trouble but cannot remember much about it to help the OP.
Possibly, you are being too tense, so just try to relax. Think of the aircraft in gusty conditions more like a boat that you are guiding on a heavy rolling sea - don't try to prevent it moving, but try to anticipate and gently counter any movement away from your desired attitude and flightpath, and just keep bringing it back to where you want it. Smoothness !
