This is just a personal opinion, not from the Committee.
Personally, I feel that when we expand the RTW aircraft available for team flights and kickoff events beyond the default aircraft, we get into too much rule complexity. Which model by which company/ group/ individual is accurate? What should be the aircraft size/ type cutoff? Etc.
I, like almost everyone else, enjoy flying my different non-default aircraft, especially those I felt were good enough to pay money to obtain. However, I also believe those are better suited for special events like are hosted here in SOH and FlightSim throughout the year.
Since the Navajo saw a lot of service in South America - what about a 4,500nm event crisscrossing the Andes in May? Twin pistons min 6 seats, max 10 seats? Navajo, Queen Air, Aero Commander?
