Hi! Michael
IMHO there has been insufficient attention paid to this question of
loaded toe in. G-PTAG is too heavy on tyre wear and when winched
backwards up the trailer ramps the reverse toe is really excessive. I
last used washing up soap on the ramps which shows the tyre scrubbing
instead of deforming.
It almost calls for a control system at the top of the gear legs to be
able to "vernier" the toe setting?

Duncan,
I can not give you any ideas how the tracking will change once the plane
is
loaded. I believe based on the geometric setup, the gear will flex out
(getting wider) and will toe in. I am not sure yet how I will be able to
measure it but definatly will try once the plane is loaded but this will
still take quite some time. This summer I hope I get the wings closed
and
all liftpins, crossbar and the flap drive tube in.
