Hijacking the thread slightly, the only Pitts I've found on the internet which looks to be rentable solo in the south- listed solo at £225/hr- is the one on the West London Aero Club site which is based at White Waltham. Don't know how much of a deposit or how much blood you'd need to supply them with though for them to let a 100 hour pilot loose on it!
Anyone know of any others?
I do have a lovely S1D for sale in my hangar if you'd like one!
£500 do???
