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.

Michael,
Any thoughts (or measurements) as to how the tracking changes once the
weight of the aircraft is placed on the legs (that have been set-up to
zero toe-in/toe-out)?

Hi Rob,
The complaint I have is to myself that I do not find the time to do
more
building. I enjoy time spend on my plane. The point I tried to make
is
that
the builder spend quite some time on the web for the main gear
sockets.
Even without the top on you spend a lot time bending over.
Building should be fun. It is more fun if you work smart and try to
have
as
easy access as possible. To me, time spend building is therapy. What
you
don't want is therapy after time spend building so work smart and
enjoy
the
quality time spend with your project.
What I did, I used bondo and stuck 5 reference points to the garage
floor. 3
along the centerline of the fuselage. One in the front, one in the
center
of
the main gear legs and one in the center under the fin. all lined up
and
on
the exact same height and in level along a line.
Then I bonded with bondo the endpoints of the main gear legs to the
floor.
Again made sure with Pythagoras help that it was square to the center
line
and on the same
level.
After that I rolled my fuselage cradle over those points and used M12
threaded rod as a height adjustment to level the fuselage over my 3
reference points along the center line and clamped the main gear legs
into
position.
This kept the fuselage the whole time igid and secured in place.
I kept this setup in place till the top fuselage was bonded on.
Nothing
moved and all is plum, squared and level.

Just curious, how many of you fitted the main gear leg sockets
before
you bonded the top on.
