Competitive Analysis: The Central Engine Advantage
Thrust line vs. Center of Gravity
Thrust line co-linear with center of
gravity: no pitch-power coupling.
Thrust lines offset from the center of gravity produces pitch-power coupling issues.
Tail Arm
By keeping the engine as far forward as possible the tail arm can be increased. A long tail arm is favorable for stability and thus improved handling qualities. See more in the Configuration Advantage section.
