d) For the smallest outside diameters (21.3 mm to 33.4 mm [0.840 in. to
1.315 in.]), rotate the tail outward, as far as possible, so that the tail wheel is
positioned farthest from the center of the setup pattern (see Figure 2-10 on
page 30).
e) For all larger diameters (33.4 mm to 114.3 mm [1.315 in. to 4.500 in.]), first
fully rotate the tail outward, and then fully inward, so that the tail wheel is
positioned closest to the center of the setup pattern with the correct spring
load (see in Figure 2-10 on page 30).
