Wheel base (L) - the horizontal distance from the tailwheel weight point
(center of axle) to the main wheel weight point (center of axle).
L = __________________ Inches
b.
Main Wheel Station (D) - the horizontal distance from the main wheel weight
point (center of axle) to the datum line.

b.
Left Main Wheel....….............= ____________ Lbs.
c.
Tailwheel, with tare =____________Lbs., minus tare of _____________ Lbs.
= net Tailwheel wt. (T) of _________________ Lbs.
