Amati have finally released some info about the weight of the model. The total weight of the hull with motors and receiver and controller and servo and shafts and lead battery is 2.9 - 3 Kilos All superstructure parts will be about 1.5 -1.8 Kilos To let the model stay in correct position into water we fit inside in the hull 700 grams of weight (front part) In that way the total weight could be calculated as: 3 Kilos + weights inside 700 grams + superstructure 1.8 Kilos = total maximum weight 5.5 - 6 kilos The model navigates well without any problem. Unquote. 700 grams of ballast sounds a good amount to me. Enough margin to allow for a heavy build (for those who are "generous" with the epoxy ) and/or to add those little extras like the working guns, radars, scale armour piercing rounds, duck scarer, etc. Not so much that it's a pain to fit tho..... I reckon a few strategically placed fishing weights held in place with silicon sealer, but there must be a 100 other ways of doing it. Who's going to be the first with a working ballast system

Well thats good news for those building with the three motor setup, as it allows for the extra weight of the extra motor, and speed controller plus a decent battery pack. I have used nearly half a bottle of glue so far, and with varnish, paint etc we wont need 700g, it will be less I expect.

The Superstructure weight makes it sound like they dont know for sure which may also suggest they have not yet completed the RC prototype...just a thought

2 Kg almost for the superstructure, fortunately most of the weght is fairly low down in the Hull.

2 Kg almost for the superstructure, fortunately most of the weght is fairly low down in the Hull. compared to other ships (e.g. titanic) the superstructure has a smaller width, especially in the upper area this makes the weight of the superstructure less critical ...and 6 cells with 150 grammes each located deep down in the middle of the hull help a lot to keep the ship stable markus

Slightly off topic anyone know how tall the model will be?

I heard somewhere about 11 inches to top of mast.

The Superstructure weight makes it sound like they dont know for sure which may also suggest they have not yet completed the RC prototype...just a thought the weight depends on the amount and type of paint and glue used on the model I think.... results may vary... beginners will probably be a bit worried about not using enough glue and thus tend to use too much of it and make the ship heavy... at least, that's what I think....

i should'nt worry too much about the weight of the superstructure, she has a nice wide hull, the superstructure will raise her matacentric height a bit and give her a nice steady roll, I hope!!

Long as she does not roll right over, she has a history of that!!

I wouldn't worry, she's wide enough and even if she wants to roll over you can add some lead in the keel it's not like it's going to sink her immediately.... if you need to add ballast to make the ship lie stable it is best tu use lead shot and use epoxy or something similar to glue it to the bottom of the hull, it's easier to get the ballast as low as possible that way... it's also easier to get the exact amount you need in the hull... lead shot can be easily made yourself, al you need is an old metal s****, a blowtorch, a bucket of water, some pieces of lead, and something to attach the s**** to.... then you should drill a 1mm hole ( a 2mm is possible too but I think the lead shot will be too big...) in the s**** and attach it to something sturdy and heat resistant... put the bucket of water underneath it and put a piece of lead in the s****... after that you must liquidize the lead with a blowtorch making it drip through the hole into the bucket of water, where it should harden again.... mind your hands though as you could get some nasty burns!!! this method is also used to balance model airplanes as the amount of lead can be precisely measured and it is much easier to get the lead in tiny places this way edit: why on earth does spoon get censored hint: you can eat soup with it....

Sounds to me like a blooming danerous way of getting hold of ballast Most model plane flyer's use readily available double sided lead gram weight strip, or maybe a visit to a fishing tackle shop is better than the risk of burning yourself or the house down
