The Rear Frame Mounting Block design provides superior tail control and authority, with an Aluminum 6061-T6 crossbar construction that prevents flex during high-torque maneuvers of both the helicopter rear frame section and the connected tail boom braces. The upgrade incorporates the landing skid mounts and crossbar into one high-strength design; offering significantly improved stiffness and strength of this critical area for tail support and resultant control.
