FH knows of what he speaks! Definitely take note of those comments followed by "Trust Me on this!"
I would add never....never....never...never hit the starter button until you can see both blade tips and have your grubby mitt on the blade tie down. Trust me on this!
Also....if the aircraft is heavy....torque, Temp, or N-1....or any combination of the three are at max.....don't be stomping any pedals. Be as light and steady on yer toes as you can be.....else you shall have need to chat with the Engineers and perhaps the Boss Fellah.
Also....never carry yer fat wallet in your hindend pockets....it will give you a crook roll attitude and lumbago. Jet Ranger seats are a crime against Humanity. If you are required to fly them for extended periods of time...say...anything over about five minutes....invest in some Oregon Aero seat cushions or retain a first class Chiropracter.
