Very interested to understand why you think that.

when you come to the construction of motorized gun turrets would you share your work with us? I use Micro servos to rotate the turrets but they have a limited radius, not as much as would be in scale. How can one increase the radius of a servo?

Google/search "servo hack" and you will see that many things can be done to increase the radius.

I used this for the travel of the bow gun on a Vosper torpedo boat http://www.servocity.com/html/180o_servo_stretcher.html. Mounted a mini-micro servo on its side on top of the directional servo , ran a wire to the gun which provided elevation. It uses 2 channels to operate the gun. The build of the Vosper is here - http://www.rcgroups.com/forums/showthread.php?t=1374839

Action do a thing called a "servomorph" that not only allows you to adjust the travel, but also the rate of rotation. If the servo/turret connection is not direct, but through a linkage, you can get more travel that way as well. Just a question of having the room to mount stuff.

Nice thread!

I've got 2 x 1:200 scale Bismarck projects on the go at the moment. The Hachette model and the Trumpeter. It will be awhile before they are seaworthy though. Both will have brushless motors and servo powered turrets.

Bismark RC Build: Deck and Hull Fit

How does the deck fit on the hull and how will you take it on and off to get to the batteries, motors, etc. since you are making it RC?

And more pictures please!!! I know you guys are having fun with this, but SHARE!

Any wisdom? Any problems?

Patsy

I don't see a need to remove the deck for access. Bismark and his* contemporary German designs seem to have been built with modelers in mind. There is a single block of superstructure with effectively a raised coaming built into the design, which leaves a big enough hole to work through.
My 1st (not RC) boat was the Airfix 1:600. Later was the Heller 1:400 Tirpitz, this time with radio. No problems with either. Its just a case of thinking ahead and arranging things so that items that will need access can be reached, other stuff can go in less accessible areas.
*Germans regarded their warships as masculine.

What size motors was used in this? And has anyone used more 3-4? If so, what was the results?

I am quite frankly surprised that this one measly, half-comatose build log begun by a kit manufacturer of all people is all that we have for the latest in RC plastic. There's not even a 1/200 Missouri thread or a Hornet CV-8.

Maybe the introduction of these kits marked a threshold for the usual crowd here; the asking prices being way too much to pay for simple, plain, unrefined styrene (albeit in nice shapes)...

Patsy, the Bismarck (with a "C") only needs three motors, one for each shaft. Any more would be overkill.

Thanks, we decided last night we would use 3 with the other electronics we will add. This is one big BEAST! But since I do not have to deal with the photo etch, I am happy!

It would be interesting to see the aeronaut Bismarck built along side as it is in the same scale.
