MK Dual Elevator Bellcrank

This setup allows the use of one elevator servo to control two elevator halves.

Servo drives center arm, outer arms drive elevator horns. ELIMINATES any differential throw to the elevators which causes unwanted rolling action. Ball bearings on each end of the shaft keep action smooth and friction and slop to a minimum. High strength molded fittings, suitable for all pattern planes up to 2-meters with rear fuselage thickness under 1-7/16".
