Control stick assembly for radio control equipment

A control stick assembly comprising:

• a movable control stick;
• first and second movable lever arms;
• means for urging the first and second lever arms together;
• a normally latched movable member;
• a first pin attached to the control stick and disposed between the first and second lever arms, the first pin being movable as the control stick moves to carry the first lever arm away from the second lever arm in opposition to the urging means when the movable member is latched, thereby resisting movement of the control stick;
• the normally latched movable member being adapted to track the movement of the first pin when unlatched;
• a second pin attached to the normally latched, movable member and disposed between the lever arms, the second pin being movable as the movable member moves when unlatched to permit the urging means to move the second lever arm toward the first lever arm, but being stationary and preventing the urging means for moving the second lever arm toward the first lever arm when the movable member is latched;
• means for unlatching the movable member to move the second pin toward the first pin responsive to the urging means;
• and
• means responsive to the movement of the control stick for producing a signal having a characteristic related to the control stick displacement.
