Thanks everyone.
I was told about the tail rotor authority - or lack of - problem. Didn't have any trouble when I flew it, 2 up in lightish winds. Seemed to climb well and no problems with hovewring turns etc.
As Rich Lee said the experience will be good, having flown only governor equipped machines before.
Still think I will probably go ahead with it if finances work out OK as the deal is a very good one. Also its going to be used for keeping my hand in and a few jollies over a couple of years or until I get paid for flying, so not too worried as won't HAVE to fly if the conditions aren't good.
Watch this space!
