<DIV> My understanding of why we try to move the wheels as close to the C.G as possible is to increase yaw stability on the ground (decrease the tendency to ground loop). Tail draggers are inherently unstable because the landing gear is located in front of the C.G. Since we don't have brakes on modern Pattern planes, the wheels can be pretty far back without causing much of a problem. Especially on smooth surfaces. The closer you place the wheels to the nose of the airplane (further ahead of the C.G.), the more tendency there is to ground loop. Also, it sometimes makes it hard to get the plane to rotate if the wheels are too far forward. </DIV>
<DIV>If Pattern planes were designed with the gear location further back, we wouldn't need swept gear.</DIV>
