Hairyman,
I choose not to - for the simple reason that you never know when another whisk, a plank, a blimp, a bimbling engineless (radioless) plank, microplank or bloke with a parachute and big desk fan strapped to his back might violate your airspace and require a bit of rapid wrist action for avoidance.
I have had to do this on the odd occasion with far too little warning to go loosening frictions.
Most trips I do are 10-25 mins max so it doesn't get too tiring. I have 650 hrs (200 in R22 and 450 in R44 Clipper II)
