Mark the position of the straightedge in both forward and aft positions and join the two points,
repeating the same procedure for the opposite side.
Take measurements from the straight edge positions to the centreline of the fuselage, repeat
for the opposite side and compare the numbers to see if the wheels have toe-in or toe-out. The
wheels will naturally want to rotate outwards when the aircraft is at gross weight, so it is
recommended to have a slight amount of toe-in to allow for this.
If adjustments are required, washers are used as spacers between the stub axle and the
undercarriage leg. Typically 2 washers are required on each of the lower stub axle mounting
bolts to give the wheel slightly less camber, and usually only one half size washer installed on
either the front or the back two stub axle bolts is sufficient to shift the toe in/out.
Pack with flock, reinstall and tighten and leave overnight to cure before using the aircraft.
