I really like the new WBB 44 tonners, warts and all. I noticed the hood on the WBB does not exactly match photos of the prototype, but I'm fine with it. Having taken apart and modified three, and bashed two, I can attest to the fact that there isn't much room, particularly width, to give away on the inside: no doubt Williams could have designed custom boards for this model to allow it to narrow the hood, etc., but I understand why they did not and I'm pleased: there is a bit more room inside for other "stuff" and I think that is a plus (smoke? I hope, eventually). It's a nice little model which is somewhat challenged as to both traction and power, but I run my pair just about all the time.
This thread and the mods being done by Gunrunnerjohn and others interest me a lot. So far all I did was wire the motors in series, make cosmetic changes to turn one into a calf, and put a bigger speaker (needed) in the calf. I plan to wait and make more mods later . . .
