 ====== Barrel Elevation Servo ====== ====== Barrel Elevation Servo ======
  
 +You have several options for controlling the barrel elevation movement. If you are using a stock Tamiya, Heng-Long or Taigen kit, you probably want to use the onboard [[wiki:tcb:tcbinstall:motors:onboard|Motor B output]] to drive the mechanical elevation unit directly. But if you are building a custom model, you also have the choice to use any servo or ESC by selecting **RC Output** in the Barrel Elevation motor type list on the [[wiki:opconfig:tabs:motorsMotors tab]] of OP Config. But you can also choose one more option: **Servo - Pan Effect**. 
 +
 +The servo pan effect is intended to be used with any standard hobby servo, but it modifies the way your transmitter stick controls the servo. Typically a servo will move in conjunction with your stick movements, and when you return the transmitter stick to center, the servo also returns to center. With the **Pan Effect** stick movements will actually be converted to //speed// commands, not absolute position commands. If you move the stick a very small amount in one direction, the servo will start moving very slowly in that direction and //keep moving// in that direction until you return the stick to center. Stick centered means "zero speed," but it does not mean the servo will return to center. For that you will have to move the stick in the opposite direction to bring the servo back. The farther away from center you move the transmitter stick, the faster the servo will move in the specified direction. When the servo reaches its mechanical limit, it will stop.

 +If this explanation is hard to understand, just watch the video below! It explains everything you need

 +**Note:** If you do select a servo for turret elevation, you may also want to set custom end-points on your servo travel. But because the radio's turret stick is used for more than direct control of the turret motors, it is not practical to use the transmitter's end-point settings to do so. Never fear, you can do it much more easily using the TCB's servo-setup menu, see the [[wiki:tcb:tcbinstall:servobarrel|Barrel Elevation Servo]] page for more information.
