I've never flown one, but the 'coupe had spring-mediated control linkage
between the rudder and ailerons which provided automatic control coordination.
This worked very well to prevent the cross-control stall problem, but made
crabbing into a cross wind and slipping more difficult...not impossible. The
benefit of good design eliminating pilot error is incredible.(witness the
cessna fuel system) and can extend to the broadest level of design...the B-33
Debonair practically lands itself, and this has saved many a dollar for tired
pilots at the end of long cross-country flights. The plane has 80 gal tanks,
and can safely travel for 6 1/2 hrs. You can't believe how hard it can be to
land at night after dehydrating at 12.5k ft. all afternoon and into the
darkness. Peter
