There you come again, lol. First as most of people know, Im not a fan of clark electronics, but you dont have to do all that ninja master stick codes to control your tank anymore. Just program your radio and done.

Also with aftermarket boards you can:
Select the tank class. From one life to infinite.

Choose normal or piercing rounds (piercing rounds takes two lifes at once)

Set the amount of ammo your tank is carrying. For example in my sherman I have the same rounds as the original tank has.

Machine gun combat too. Which damages soft skinned vehicles.

At home after combat to read the statistics, who hitted you, when and so on. Also live, on your radio, while battling.

Simulate tank damages, like broken tracks and so on.

Also you can change all the sounds to wathever you like it.

Fully compatible with all brands at the same time. Tamiya, heng long, taigen and so on battling together.

And more options that I am missing now.

Meanwhile with the stock tamiya electronics, well... You can get bored of them after 15 minutes.

I just sell them as soon as I buy a tamiya kit. For me, they dont worth a dollar.
