SET-UP ADVICE PLEASE.

Hi,Thank you so much for all the advice,it is most helpfull,I will have a look at some modern naval warships,but I quite like the idea of a patrol boat,going with one prop and motor is I think a good idea for a first time build and your advice on marking out on paper is really usefull.No doubt I will be back with more questions,but I have quite enough to be going on with.Once Again thanks for your time and patience,with help like this I am sure I will get there.I am so glad I found this site.
Thanks Once Again,
Regards as always, Pete.

HI yes seen the model - made by NPS Plastics in Blackpool. Looking at the model I don't think it is the right shape for HMS Repulse. This hull will work very well with a single prop and motor and for your first model this will make construction much more straight forward. The warships that would fit this hull are some of the modern RN warships that have raked bows and flat transoms at the stern. You could build a Police/Patrol boat or an open cabin fishing or day boat which will not require much superstructure. Recent copies of Model Boats or Marine Modelling international carry articles and pictures of such vessels and they both sell plans if you want to make a more detailed model.
To mount the motor and prop shaft and propeller you need to have a shaft long enough to allow the prop to clear the hull and allow your motor to clear the inside of the hull. You cut a hole in the fibreglass where the prop shaft enters the hull. The longer the shaft the lower the motor can be mounted in the hull. You can obtain these up to about 20" long. ideally you need to decide on the type of vessel before you fit the prop as you need to allow space for your Motor,Radio, ESC and battery. if possible keep all the heavy bits low down and towards the middle so that the boat is not bow or stern heavy. Deck openings in the rifgt place will make subsequent work so much easier.
You can approximate the prop shaft length by drawing the keel outline on a piece of paper. Mark the prop position allowing for clearance of your chosen size and leaving space for a rudder between the stern and the prop. Draw a straight line to where you want your motor. I suggest you use a universal coupling between the motor and shaft so you will need to leave space for this. Measure the distance from the prop to the coupling. Moving the motor higher or lower will shorten or lengthen the prop shaft. The motor can be mounted on a wooden block attached to the hull. I use car body filler to fair in the prop shaft to the hull. if the shaft sticks out more than a couple of inches you may need to provide a bracket for support both inside and outside the hull. Make sure that you get the shaft in straight (bow to stern) and that the rudder is vertical and directly in line with the centre of the prop.
There are some cheap 50 amp ESC's that should suit a Johnson on 12v with an SLA.
Hope this helps but please keep asking if you are not sure orneed more help 😀

HI Again,I do not have any pictures of the hull but if you would like to see it have a look on E-Bay,type in model boat hulls,about 3/4 down first page you will see listing for large model boat hull,5 foot long,GRP £35,see sellers other items it is there,says suitable for Destroyer,Frigate,aircraft carrier,passenger liner etc.49" long,11" beam,8" deep,this is the hull I am waiting to be delivered.As I said I am not looking to do a detailed model,just a copy with a lot of artistic licence,The actual structure I am not to worried about,its the running gear I don't quite get yet,this is why I would like to keep it as simple as possible,as in,battery,speed controllers,with motors,shafts and props all in direct line,if it means smaller props and different size motors that would be fine,like I said I have not bought these items yet.By all means please have a look at the hull,see what you think would be an suitable model to build on it,I am open to any ideas.Once again thanks for all your help.

HI Pete
Do you have a picture of the hull you have bought? if its a commercial production, who's the manufacturer and was the hull advertised for any particular type of ship? Do you have any plans or pictures of HMS Repulse? if the hull has similar lines then there is no reason why you should not use it. Aircraft carriers, such as Illustrious are rather a different matter and I would not recommend building as your first model. As to the type of model this is really down to your choice. if you advise a bit more about the hull and give s few preferences Ie warship; passenger vessel etc I will try to help 😀

SET-UP ADVICE PLEASE.

HI Dave,Like I said earlier I am new to boat modelling so am not sure of what I need,the model battlecruiser I was thinking of building was going to be based on a pre-formed resin hull which is 49" long with a 10" beam,perhaps I have got it wrong and cannot build said model on this hull.It is not a problem as I have not started to build yet,I could do any other type of navel vessel,I have seen a model of the aircraft carrier HMS ILLustrious built on the same hull,and just thought if it was a big enough hull for that it would be big enough for the Battlecruiser,Oh well back to the drawing board as they say,lol,Thank you so much for your input,if you could suggest any model I could make with this hull,and a simple running set-up for it I would be very greatfull.
Regards as Always Pete.

HI Pete
Must be a good size model. Battle cruisers were not renowned for fast speed so 600 size motors should provide plenty of power, 50mm props will need some form of reduction unit between the motors and props optherwise you will overload the motors. Two speed controllers will be required as large models need some help with motors as well as the rudder. There are more suitable motors if you have not yet bought yours. My RMS Olympic is 9ft long and uses three 555 motors with three controllers. it will actually sail with just the centre motor. I suspect you may be able to use such a motor without a reduction unit. How large is your model?
