This Tamiya sub-forum, within electronics, seemed a reasonable location; although this thread will also embrace non-electronic bits and bobs.
Here are the tanks: Full-Option; with electronic control units, and Static; which have no RC capability (but it can be added, of course).


Here's a typical DMD Control (Mulfti Function) unit, for starters.

The MF-04 is fitted to to the Jagdpanther(56024)


Here's the DMD MF-01, it's fitted to the Panther:


I wish I'd used my SLR on these, with better lighting, in order to make the images as crisp as possible.Hopefully, though, the PCB details are just clear enough.
