Hi Pondweed
The job was to design a set of running gear that would work, and be reliable and efficient,  good running time, good access to the works, and the basic system to fit later models in the range.
 Keep to scale appearance as near as possible.
A single screw, (2 channel cheapest )
B. Twin screw  linked motors,  2 channel
C independant control, twin screw  4 channel
E. full house,  three working screws. multi channel
we have done all of these in order.? model has now gone to the customer to finish off
 Not sure if you follow the thread, we never made the shafts larger, we kept to 2mm,  it was the new boss on the ends that was a special product as part of the shaft.  the props  were specially made to fit the shafts, and to be scale,
 and you can not "tweek" a cast brass prop, you have to make and cast new ones, increasing the revs will achieve little in such a heavy boat, just overload the motors, and the props have to work at the best speed, as do the motors.
 and the chances of anyone "tweeking all 9 blades to exactly the same angle is pretty remote.?
 What clear plastic turret ?
Regards

Didn't realise you were prototypeing a kit. Are they cast? They looked like brazed to my eye.

Turret: The Trumpeter site shows a clear plastic sprue. I think it also says there's 2 extra metal barrels.

I think the idea is to show the workings of a MA turret either on ship or as a diarama to one side.

In the 'new release' photos floating around the web showing the new Bismarck, it showed a bonus turret assembly in a separate box. The clear parts are in the tradition of the old Visible Man/Visible Woman educational kits, so one can see the "guts."

So, yeah, you're pretty much right on... unless there's something more sinister behind it all.  ok2

Dear Cobber
 it is not a adapter the prop end is turned brass and threaded M4 then is then brazed on to the 2mm shaft and balanced, this is so we can run big props in a heavy boat but keep the propshafts slim enough to fit in to the hull,
4mm shafts / 6mm tubes looked ridiculous and over scale plus you had to chop bgi lumps out of the hull.

question:
did you plan to substitute the Original Rudders with a new one much more performant?
