Attempt number two for an Airfix Victory at 1:180
warspite:
Decided a couple of months ago to buy another Victory, this time I want to make it work, 1. by not having it fitted with a underwater fin or motor, ideally all the weight inside and the mast a lot lighter than previously to reduce the counterbalance effect, sails would probably be furled but for those at deck level.
Just need advice for the best way to do this, yes, all weight at the lowest point and equally distributed, lightest servo(s) to pull the sails left and right etc, was actually thinking of using the kits masts with 1-1.5mm brass tube bonded to it to give some strength.
Plastic - RIP:
I built this model many years ago - I seem to remember it had an awful lot of plastic above the waterline - please post photos of how you make this work.

well I am relenting and showing a photo of the ship in the test tank, it has the fin fitted and is cumbersome to fit and remove, ideally I would prefer to remove it completely, so that is why I am looking into reducing the weight topside.
It took nearly 250-300g to work at the length it is, she's sailed only once with this fin, and although it did work the weather was 1. too cold and 2. not enough of a breeze to give the results needed to see if it worked correctly, a gust did give the chance of working but it went into reverse.

The vessel shown is what I call the 'Royal Soveriegn', after looking at the names of 100 gun ships of the line - decided to call this the least inocuious named vessel, it is a Airfix 1:180 scale plastic kit, with a keel fin weighing about 250-300g painted black.
the kit is generally built with all but the mast sections and ports closed - in fact the 'crew' is actually constructed from the guns :D , the masts are constructed from brass tube and rod, the weights did not really seem that excessive when completed, the bow sprit and a couple of davits are in brass to ensure their survivability in normal use.
Masts are sections built up from different diameters of brass tube soldered together, the spars are again sections of brass tube based on the diameter of the plastic spars and are passed through the masts and soldered together, the for and main mast are connected together using aircraft 2mm rod linkage connected to a standard sized servo (it's what was in stock), the rudder is a micro servo as is the receiver, a hitec feather.
as stated i want to build this one so that all the weight is inside the vessel so obviously the masts have to be lightened, the existing masts are really not straight enough or strong enough to be used, i think it would not take much to deform them in use, strengthing them with brass rod might be possible though hiding this could be interesting. the spars would be an interesting problem, how to incorporate brass rod or tube into a small section of plastic
warspite:
Re examined the original masts from the kit, other than the top sections being a little flimsy for my liking, they would still be acceptable for furled sails at the tops and the main and middle ones still operating, the bowsprit would be brass again to take knocks.
The sails would have to be fitted differently, definitely sew an overlocker stitch along the edges to make it neater, but not sure if it would detract from the effect as the stitch would be bigger than scale - plus I don't sew.
Getting back to the masts, the only odd thing is to make the rotating part of it flush with the deck and then it shaped to accept the existing plastic profile, so that if it does break it can be replaced with the spare set or a completely redesigned version in a tougher material.
