Stan I used Mikey at Acrodynamics.com last year in a Citibria. While it is not the same as a 4 it will give you the training. Also Mikey has RV tailwheel experience.
My schedule is busy for the next few weeks with TeamRV.US air shows, but if after that you have not found a ferry pilot. let me know.
