By the book, the maximum demonstrated crosswind component is 25 mph (note: NOT knots!) This is with or without rudder pedals. [Eat green envy you Cessna drivers.]
A reason there's no difference whether the rudders are controlled by pedals or by the linkage is that there's just not a lot of surface to the rudders. They were designed for the purpose of counteracting adverse yaw, not flying crooked. With pedals, I can stay on the extended center line of the runway with the nose pointed in line with the runway up to 15 mph crosswind component. Up to that crosswind, I can land the upwind wheel, then the down wind wheel and nose with no crab. Past 15 mph crosswind component, I level the wings in my rudder pedal plane and land in the crab -- Coupe style. In the air, the ERCO and Alon pedal kits work exactly the same. The plane was fully certified as spinproof with and without pedals. There is enough rudder travel and surface to let you vary your slip for improved glide-slope control during your approach to landing. Ground handling: With the tail up to correct height (75"), the wings dump lift as the nose comes down. The up-wind wing won't lift problematically up to 25 mph direct crosswind. For crosswinds faster than 25 mph, you'd BETTER have your tail up to dump lift or you'll get increasingly unpleasant lifting of the up-wind wing. The ERCO rudder pedal kit keeps the nosewheel ground control on the steering wheel. This gives you, I think, more accurate ground control but no improvement of the after-touchdown wing-lift than a two-control coupe. The Alon rudder pedal kit is what I have. With this, the ground steering is done by the pedals. Because of this, after touchdown, I can turn the ailerons into the wind to totally prevent up-wind wing lift. I even get some on-the-rollout air braking from cranking them all the way to the up-wind direction. On the ground, the Alon kit lets you prevent up-wind wing lift, giving comfort (to me) at 30 or more mph crosswind component. I do wish I had that extra leg room, though.
