    Same load as usual for day-to-day local ops, minus the pilot.
    Tailwheel head angle looks about level or maybe even leading a little (vs trailing).

    Pretty flat but not practiocal to change without replacing the stinger. If tightening the pivot works I would go for it. Easier to fix with spring arch on a Cub.

    I replaced the spring on my 180 with the one that Airframes sells. It has a bit more arch. Baby Bushweel only shimmies if I have it really loaded aft and on pavement.

    That stinger is $2200.
    If replacing mine is the solution,
    I think I'll continue to mask the problem.

    I think it's just an adjustment thing though--
    so far no shimmies, after tightening the kingpin nut 2 flats worth.

    Something else to consider. I used to work on an ag plane that needed a specific brand/model of tire on the tailwheel. The tire was one of the styles that had a flat face across the tread instead of the more typical rounded type. Any other tire and the tailwheel would shimmy badly no matter the load on it.

    Maybe this install would respond to another tire?
