The default board settings are Tamiya IR. Weight class is set by dipswitch on the board, same as with Tamiya. It's all of one mouse click to change IR to some other protocol but Tamiya is the default.
As mentioned before, there is no way to make this truly "plug-and-play" because you at least need to go through the radio setup routine. The TCB has no idea what radio you might be using, given that it is compatible with a countless number of them. So one way or another, the user is going to end up opening the OP Config program and clicking their mouse. This is par for the course for aftermarket boards.The difference with the TCB is that you aren't programming your board blind with a TV remote or jumpers, never knowing if the settings you gave it stuck or not. You see right there on the screen all your channels moving as you move your sticks. It is very clear and easy to do.
There is no radio setup with Tamiya because Tamiya come pre-configured for the Tamiya radio which is included. That saves you setup time. The cost is that you are limited to 4 channels.
I hate to bash my own product, but it needs to be said - if you want a plug-and-play system more than anything else, do not buy the Open Panzer TCB. Also do not buy the Clark, the IBU, the El-Mod or any others like them. Basically you have one choice which is the Tamiya setup. With IR capabilities it will set you back many hundreds of dollars, you will be limited to 4 channels and goofy stick movements to control things, BUT it will work out of the box (except for high intensity flash which will go up in smoke after the first week).
But if you are willing to sacrifice a few mouse clicks for greater flexibility, then the TCB is a good option.
