1. A leverage-reducing landing gear system for an aircraft, said leverage-reducing landing gear system comprising:
(a) said aircraft having a front, a rear, a top, a bottom, and a central vertical y-axis perpendicular to a horizontal x-axis and extending from said front to said rear, said aircraft having an airframe and landing gear, said aircraft having a center of gravity;
(b) said landing gear including a first primary landing gear leg and a second primary landing gear leg, said first and second primary landing gear legs positioned on opposite sides of said central vertical y-axis;
(c) at least one first shock absorber functionally connected to said first primary landing gear leg, said at least one first shock absorber connected between said first primary landing gear leg and said airframe, said at least one first shock absorber angled upward from said first primary landing gear leg toward said central vertical y-axis such that said at least one first shock absorber and said horizontal x-axis form an angle less than 30 degrees; and
(d) at least one second shock absorber functionally connected to said second primary landing gear leg, said at least one second shock absorber connected between said second primary landing gear leg and said airframe, said at least one second shock absorber angled upward from said second primary landing gear leg toward said central vertical y-axis such that said at least one second shock absorber and said horizontal x-axis form an angle less than 30 degrees;
(e) wherein said landing gear is fixed landing gear.
