...may I also suggest that for realism, you set out on a two-hour cross country on a warm, soporific day where nothing happens for the first 90 minutes, and however hard you try to concentrate your mind wanders to the business you're heading for...
then when the engine catches you out the blades will be clapping over your head before you can say goodnight nurse.
PS: Old Bill Barrell, who died of natural causes, once took the rrpm down below 80 percent on me "as a demonstration" and despite his track record and the fact that we were halfway through the FI course I told him I'd refuse to fly with him if he did it again.
