Thanks Ande,
Yes, they've driven down from St. Louis and Wisconsin since there don't seem to be any RV transition trainers above the Mason-Dixon line listed on this site.
Three hours has been a good figure for guys who are current but one guy had to have 5 hours to suit the Insurance company since he's almost ready to fly his brand new RV 4. He has 140 hours in his Cessna 140 (a beautiful restoration) which he flew up here from South Georgia this week.
Another guy was really rusty and not nearly as "good" as he said he was and it took a little over four hours. Bear in mind that my airplane is a trike but the flight characteristics of a 6, 7 and 4 are very close.
The guys from up North had invested 7 years or more building their airplanes and they easily justified the 1000 mile/three day trip and brought the wives along.
The difficulties I see the most is a lack of enough right rudder input during takeoff roll and climb, which is substantially higher than a 150 or Skyhawk. The second is adjusting to the oh-so-responsive controls and thirdly, slowing down. After they see that 1700 RPM's will hold 110 MPH in the pattern, the rest is easy if they don't come banzai charging into the pattern at 185 MPH

Pierre
