My Sonex purchase included a bunch of extras, including Matco Wheels, breaks and master cylinders for differential breaking for both pilot and passenger. Differential breaking requires a full swiveling tailwheel. I purchased the Fly Boys Accessories Sonex tailwheel, consequently, I’m getting rid of the limited swivel tailwheels.
If you have toe pedal operators for your differential brakes, the original tail wheels work fine., 14 flying seasons on mine with no problems. The tail; wheel connected to rudder gives a bit more control in crosswind ;landings, and when one brake is jammed on, the tail will slide around much like a free swiveling one.
How does it break out? In big crosswinds we are stick full back to plant the tailwheel, with lots/most or all of the rudder. It would be a bad day for us if it broke out when we needed full rudder!
So that seems like it will unlock at or close to the rudder stops, unless I don’t understand the system. With the amount of aerodynamic rudder power in the Waiex, that would be a bad thing. I’ve used full travel for crosswinds before.
So far we have had to shut down and turn the airplane by hand twice during taxi. Often when parking as we can’t pivot. I can live with the fixed tailwheel.
I’m building a Corvair powered Sonex as well and looking for the 6” tail wheel (direct steering). Would like to buy the one in the box is if still available.
