1. An apparatus including first and second potentiometers, said potentiometers drivable by a control stick comprising:
- a housing means;
said first and second potentiometers comprising respective first and second potentiometer housings having respective first and second rotatable shafts mounted therein;
first and second gear means affixed to said first and second potentiometer housings, respectively, said first shaft extending through said first gear means and being rotatable with respect to said first gear means;
said second shaft extending through said second gear means and being rotatable with respect thereto;
first and second orthogonal fork member means connected to said first and second shafts, respectively, and mounted in said housing means for rotation through an arc with respect to said housing means; and
means for driving each said gear means pivot the attached potentiometer housing with respect to the shaft mounted therein, thereby adjusting the potentiometer setting corresponding to a particular position of said form means.

7. In a joystick control apparatus, the apparatus comprising:
-
a potentiometer having a body and a shaft means responsive to movement of said joystick; a gear means fixed to said potentiometer and rotatable with respect to said shaft; and means for rotating said gear means and body to a selected position with respect to said shaft, thereby adjusting the characteristic of said potentiometer associated with a selected position of said joystick.

8. An apparatus drivable by a control stick comprising:
-
a housing means; first and second potentiometers having respective first and second rotatable shafts; first and second gear means affixed to said first and second potentiometer, respectively, said first shaft extending through said first gear means and being rotatable with respect to said first gear means;
said second shaft extending through said second gear means and being rotatable with respect thereto;first and second orthogonal fork member means connected to said first and second shafts, respectively, and mounted in said housing means for rotation through an arc with respect to said housing means; first and second detents at one end of each of said first and second fork members; means for driving each said gear means to pivot said potentiometer with respect to said shaft, thereby adjusting the potentiometer setting corresponding to a particular position of said fork means; first and second return means each having a beveled surface, a contoured surface and a pivotal mounting means at a first end thereof mounted in said housing; means for biasing a second end of each said return means in a position wherein said first and second detents and said contoured surface interact to return each said fork member to a selected position of its respective arc; and switch means slidably mounted in said housing having a cammed surface thereon, said cammed surface being movable with respect to a said beveled surface to pivot a said contoured surface out of contact with its corresponding detents, thereby preventing said biasing means from returning said fork means to said selected position.

9. An apparatus drivable by a control stick comprising:
-
a housing means; first and second potentiometers having respective first and second rotatable shafts; first and second orthogonal fork member means connected to said first and second shafts, respectively, and mounted in said housing means for rotation through an arc with respect to said housing means; first and second detents at one end of each of said first and second fork members; first and second return means each having a beveled surface, a contoured surface and a pivotal mounting means at a first end thereof mounted in said housing; means for biasing a second end of each said return means in a position wherein said first and second detents and said contoured surface interact to return each said fork member means to a selected position of its respective arc; and switch means slidably mounted in said housing having a cammed surface thereon, said cammed surface being movable with respect to said beveled surface to pivot said contoured surface out of contact with its corresponding detents, thereby preventing said biasing means from returning said fork means to said selected position.

10. Joystick apparatus comprising:
-
a housing; a plate; a potentiometer means having a shaft and a body for providing a variable resistance in response to rotation of said shaft, said potentiometer body being pivotable with respect to said housing and rigidly attached to said plate; gear means integrally formed with said plate; drive means for rotating said gear means, thereby rotating said potentiometer body with respect to said housing and said shaft to thereby impart a bias setting to said potentiometer; and joystick means for rotating said shaft.

11. An apparatus drivable by a control stick comprising:
-
a housing means; potentiometer means having a rotatable shaft; fork member means mounted in said housing means and connected to said rotatable shaft for rotation with respect to said housing means, said fork member means having detent means at one end; return means having a beveled surface, and a contoured surface at a first end, said return means being pivotally mounted in said housing means at the first end; means for biasing a second end of said return means in a position wherein said detent means and said contoured surface interact to return said fork member means to a selected position; and switch means slidably mounted in said housing means and movable with respect to said beveled surface to pivot the contoured surface on said return means out of contact with said detent means, thereby preventing said biasing means from returning said fork means to said selected position.
