I always seem to initially wind up on a three-position switch with the settings for all three surfaces at 0, 20 and 25%. Maidens at 0%. Once the flight modes are trimmed, then I try the gyro. Occasionally, I end up later tweaking an individual surface a bit more or less. But starting out, all three surfaces are set the same. It is always better to start out low, work your way up, and then check each individual surface (i.e. as you individually increase each surfaces setting, check how the plane reacts to quick stick movements and higher speeds.)

Not saying this is the right way to get there. It is just how I do it because fiddling with the knob on a maiden can be a bit taxing, especially if you inadvertently start out with the knob in the high position versus off. IMHO a lot goes on during a maiden and there is no need to be fiddling with the gyro let alone a gyro on a knob during a maiden.
