There is another feature of the mono undercarriage which is apparent only
with the aircraft suspended. The damper block has enormous hysteresis with
hours of recovery time. Years ago Ron Swinden supplied me with a compression
curve when I had illusions of using it's Hook's "constant" for auto-loading -
(you can't, it isn't !)
This means that unless you park your aircraft with the weight off the wheel
!, the "pre-compression" you put in during construction is just not there and
the bolts go slack. So there is shock to the system, as about 3/8" slack is
taken up on first arrival. Another bit of precious prop. to ground spacing
lost.
Perhaps later blocks are different, but many must be flying like mine.
