....about as much fun as practising bleeding.
Kingtoad,
Half sounds about right - the 421s with winglets used to go very well but I think the spar life was reduced to about seven thousand hours.
If you are thinking about old pressurised piston twins then you should consider a Duke, B60. Personally, I'd stear clear of that class of old aeroplane now. I reckon operating one would be about as much fun as practising bleeding.
Cheers,
