I like your spin Ed, that the handbrake "problem" is only a misconception, but I'm sorry it just won't wash. The handbrake definitely sucks.
Differential toe brakes would transform the aircraft's ground handling for (should be) only a minor additional cost.
During my second Texan flight last week, I flew from the right seat. Much nicer, for me. I prefer the stick in my right hand, and the minor controls in my left hand. If (when?) I have my own Texan, I shall set up key instruments on the right and configure for right-seat piloting. No law against it that I know of.
Actually, there is a photo of the right hand drive Texan config on the Fly Synthesis website. At first I thought the photo had been flipped, but then I saw all the instruments read correctly.
If those egg-beater drivers can do it from the right, so can we.
Cheers
