| The TCB allows you any control scheme you want, even unusual ones. Want to control the tank's forward speed with a slider on the side of your transmitter? Ok, you can. But the basic assumption is that you will use one of the sticks on your transmitter to handle movement and steering. We will call this the "drive stick." The drive stick can be the left or right stick of your transmitter depending on your preference. | The TCB allows you any control scheme you want, even unusual ones.

| When using a drive stick the controls are fairly intuitive as shown in the graphic. | When using a drive stick the controls are fairly intuitive as shown in the graphic. There is one thing to know - the TCB allows you to set a Change Direction Delay which prevents the model from changing direction from forward to reverse (or vice versa) without first coming to a stop, returning the stick to center, and letting the delay expire. The delay can be set very small, even a fraction of a second - or it can be disabled completely. This delay can help save your gearbox and drivetrain from wear and tear, but if you don't know it exists you might think something is wrong with your transmitter. See the [[wiki:opconfig:tabs:driving#driving_delays|Driving tab]] in OP Config to adjust this setting. |

| When the acceleration constraint is set to a high level it can make driving much more smooth, but it can also make starting from a stop feel sluggish and you may have to use a lot of stick movement to initially overcome the resistance of the drivetrain. For this reason the TCB has a "nudge" feature that lets you specify a short length of time and a throttle setting. Whenever you start moving from a complete stop, the throttle setting will be applied for the short length of time you specified, over-riding any acceleration constraint. This has the effect of "nudging" or pushing the model forward briefly. The length of time for this effect can be very small, even a fraction of a second. When the effect is over, your acceleration constraint will take effect and future acceleration will be subject to that constraint until the next time you come to a complete stop. | When the acceleration constraint is set to a high level it can make driving more smooth, but it can also make starting from a stop feel sluggish and you may have to use a lot of stick movement to initially overcome the resistance of the drivetrain.

| By adjusting the acceleration constraint and the parameters of the nudge effect, you can obtain very precise, smooth and realistic control over your model even at very low speeds. To adjust the nudge settings, see the [[wiki:opconfig:tabs:driving#nudge_motors_on_start|Driving tab]] in OP Config. | By adjusting the acceleration constraint and the parameters of the nudge effect, you can obtain very precise, smooth and realistic control over your model even at very low speeds.

| ==== Delays ==== | Like most other RC tank control boards, the TCB allows you to start and stop the "engine." On the TCB this is accomplished by assigning any trigger to one of the [[wiki:tcb:operation:functionlist#engine|Engine functions]] (on, off, or toggle). You can also choose to start the engine from the drive stick itself if you don't want to use a trigger. And you have the option of letting the engine turn off automatically if you have been sitting at idle after some length of time. See the [[[[wiki:opconfig:tabs:driving#engine_starting_and_stopping|Driving tab]] in OP Config for these settings. |

| | Unlike most other tank control boards, the TCB also allows you to control the "transmission." The transmission automatically engages [[wiki:opconfig:tabs:driving#driving_delays|a short time]] after you start the engine (the delay is to allow the engine startup sound to complete), so you don't have to think about the transmission if you don't want. But if you do want, you can assign a trigger to one of the [[wiki:tcb:operation:functionlist#transmission|Transmission functions]] and engage/disengage it at will. While disengaged the engine sound continues to play, as does the smoker. By moving the throttle stick you can "rev" the engine, which will increase the smoker speed and increase the speed of your engine sound - but the tank will remain stationary. Also while disengaged, you will notice the smoker idles at a slightly faster speed than it does when the transmission is engaged, just as the engine would in real life. You can adjust the smoker idle speed on the [[wiki:opconfig:tabs:motors#smoker|Motors tab]] of OP Config. |

| | If you disengage the transmission while the model is moving, it will coast to a stop subject to your deceleration constraint. While coasting you may still steer and use the brake if you need to stop quickly. |
