RC airplane Stable spiral mode resulting in simple turning control where "rudder" input results in a steady bank angle rather than a steady roll rate. Let's us see RC airplane of the inertia axis.

  The weight distribution and wing position of a low RC airplane provides a good balance of stability and maneuverability. The RC airplane moment of inertia about the rotation axis is lower because it is closer to the wing, therefore rolls require much less torque and are more rapid than a high wing plane.
