Boomerangben,
I'm afraid I would disagree about the hour's flying for a trial lesson. There is SO much to take in, the concentration required and the muscles used, that after half an hour flying, you will be knackered.
....Archer.... well, I WAS.
So much so that after my half hour ended, I jumped out of the helicopter (a Schweizer so a little higher off the ground than a Robbo) and promptly fell over as my legs had gone to jelly.
Cheers
