Very simple actually, old boy.. .. .Keep the wings level, which is natural. Look at the yoke. Left horn down, then apply left rudder. Right horn down, then right rudder. Apply an application, to level the yoke and wait, don't "juggle" the rudder, let things settle then make small adjustments. It's as simple as that. You don't even need a ball, using this method. Remember yoke level, no spoiler deflection ie less drag.. .. .If you are low on the G/S, decrease the Rof D, ie increace pitch. The IVSI does not tell you what is happening, at present but informs you of what will happen if corrections are not made.
