The demostrated crosswind of 13kts is a non-issue (and not a legal limit in any way). I found them no harder to land safely in 25kt xwinds than other aircraft.
421C exactly what effect does having the rudder/aileron interlink have?
I've never flown a plane with one...but I'd have thought that a crosswind technique like crabbing in and then transitioning to wing low over the threshold (which is what I do) is difficult because of the need to cross the controls over.
