I am only a 5ft 6in (female), but I have flown assorted SEPs & MEPs.
A selection of cushions usually sorts out distance to pedals & my being able to see over the cowling. But on some twins my arms are not long enough to reach things on the far right of the instrument panel, without undoing the seat belt.
I did my tail-dragger course & aerobatics, on a Citabria. I had no problem reaching the rudder bars, but found that my feet were just too small to cover the rudders & the heel-brakes, at the same time. BUT, as my instructor had told me only to use the brakes as a last resort, this turned out to be a tremendous advantage, as I was never likely to touch the brakes by mistake!
