Inverted Airvans
Its only 4 grand for the airvan check to line and if you're a good bargain man you can get them down to less than 2!!
They really are just like a big lazy 152, although I have seen some collossally screwed up landings in them!!
Im just glad the company I work for has the wonderful little phrase "all training and aircraft conversion training costs shall be covered by the company" etched in the Ops Manual
