never wrap your fingers around a prop. There is no need. Not even the tips.
Quite so. Also, don't be afraid the engine will burst into 2,000 rpm life while you're still in contact with the prop. What happens is you walk away as you swing it. If it 'catches', by the time it roars into life you are a few feet away off to one side.
Reading FP's post, that Auster must have been a spirally-stable aeroplane to fly pilotless in circles for so long. Must have had odd handling as a result!
