............I recently returned from Florida. While there, I took advantage of the opportunity to sample a Stearman (PT-17, fitted with the W-670), at Preston Aviation, about an hour's drive from Orlando. The aircraft was in good shape, and Tim Preston was friendly and enthusiastic.
Being cheap by nature, my first thought was " it is too expensive; I'll just find a private owner and arrange a flight for a lot less". However, Tim allowed me to fly from the rear cockpit and to do all of the flying (yes, including the takeoffs and landings): which I doubt would have been possible with a privately owned airplane. This permitted me to obtain a good sense of how the aircraft handles, and the money was well worth it. If you're in Orlando, consider making an appointment.
