Hi Ian
Thank you for the info
AustinG

Ian F a good evening
you you you are an even bigger lifeboatlover as i m. I have 2 finished ( Watson and Trent) a 3rd on the shipyard Harro Koebke and a 4th delivered in a week's time.
Oh man i so jalous of your fleet
👍👍👍👍👍👍👍

Hi Ian, and many thanks for the incredible-looking fleet of lifeboats collection photograph, they all look absolutely fantastic. When you reel off the list of the various classes, the question that comes to mind is does that cover them all, and if not you must be awfully close. Many thanks for the photographs and do please post some more when the weather warms up a little. Out of interest, there is not too many miles between us, as I also live on the North East coast in Redcar, and use the boating lake on the seafront which is nice and handy. Regards, Gary.

Hi austing, these where obtained from models by design in the uk who know longer exist as a company, i painted them myself, however mountfleet models here in the UK do manufacture 1/12 figures, regards, ian

Would be interested id information on the crew how did you make them or what??

Austing

Hi gary, here is a glimpse into my toy box i have a mersey, tyne, arun, oakley, thames, shannon and waveney class lifeboats all 1/12 scale which i built myself i use a robbe futaba navy 40mhz on all of these and operate them at killingworth lake in the North East of England as i am a member of the model boat club there, I'll post better pictures of the lined up on our patio as soon as we get a break in the weather as i live at newbiggin by the sea in Northumberland, also members may be interested in knowing that it's the rnli bicentennial this yand a 2 day exhibition is going to be held at bamburgh Castle in may and i will be exhibiting all of these models , all the best ,ian

Hi gary , here is a close up o the props , which are raboesch D type part numbers rab174-11 &12 left and right hand regards ian

Hi Ian, great photo and great looking boat, and you neglected to inform us you have an implanted Lifeboat gene, and your own personal fleet of LIFEBOATS. Both myself and others would love to see some more photos if possible, (Good for the street-cred.) I would love to see photos of the hardware on the rear end, as I find the complexity intriguing. You have done a really great job in the building of your numerous Lifeboats, especially in the fine detail department, which is what it is all about. Well done, regards, Gary.

Thanks Ian for sharing the photo and information with us.

If you want, could you attach one or more photos of the propellers and tell me how much your boat weighs?

Do you have a video of the navigation (more than for utility it's for the pleasure of seeing models in navigation)?

Another photo of the inside of the arun , ian

Hi here is photos of my 1/12scale arun props are 55 mm diameter 4 blade from raboesch power pa ks are 4 12volt 5000ma nicad in parallel whi h gives you loads of duration and adds to the ballast , hope this helps, ian

Ahahahahahah, don't worry Hermank, I'm not rushing you. Do everything calmly.

At that time? These photos?
ahahahahahaha

Alessandro what a kind man you are!!!it’s a pity you live in Italy( my son in law is italian) down Sorrento.
I need to finish thé one i m building first😂😂😂😂

Will do hopefully tomorrow, regards, ian

Hi Hermank.

I don't think the diameter of your propellers is too large.

It is true that we are talking about a pair of propellers and not just one but let's wait to replace them with smaller propellers.
I'm curious to see how they are made, how many blades they have, what material they are made of and above all the pitch.
They certainly won't have the pitch written on them like the real ones do, but I'll try to get an idea from the photos you send.
For such a large and, perhaps, very heavy model, propellers of that diameter might be needed. The designer must have had his reasons.
It is clear that the engines must have adequate power or they will suffer too much with large propellers.

Alessandro what have you done to me!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
i have the RNLI plans for the Tamar 1/12 enlarged to the scale of the boat that avoids measuring and calculating all the time. My intention was to start the building after i finished the Harro Koebke. With your kind mail i had to have a look at the plans............................
madre madonna.................. the screws have a diameter of 55 mms. To me i find them quite big! Up to now i haven't received any suggestion regarding the diamet of the screws (2)
So i m curious to what other builders of this model have used and what their experience is( was). As mentionned i still got a lot of time before the built starts on my wharf.

Alessandro amigo italiano Thanks you for usefull information. As i m awaiting thé model to arrive i haven’t jumped into all thé aspects. I appreciate your fast reactions and i Will keep you posted on this fantastic site
👍👍👍👍👍

Hi Hermank.

When you opened this topic I was sure that you would receive numerous useful tips and I was waiting to read them to learn too.
I was very surprised that you haven't had much instruction so far, except for IAN F1.

I saw that the real model has a maximum speed of 25 knots (so enough but not very much, considering that modern frigates reach 32 knots). Tell me if I'm wrong.
Therefore the speed of the model must be proportionate to these standards to be realistic.
To understand which engine to put in, I would start from the propeller you need to fit, if you have no other indication.
On the real model there are two five-blade fixed-pitch propellers.
This makes me understand that it's not really a speed setup. In theory they shouldn't have a very long wheelbase.
I don't know either the displacement of your model or the dimensions (diameter) of your two propellers so I'm not able to hypothesize anything.
For the displacement, making a scale proportion compared to the 31.5-ton displacement of the real boat, I would say just over 18 kilograms, but it seems like a lot for a model. Most likely there will be fewer.
For the propeller I have no other information, I can't deduce it from the length of the boat also because I don't know if you want to maintain the same proportions with the real model.
While waiting for further information, I would use two very powerful motors (even without a mechanical gearbox) so that you can adjust the speed with the remote control stick, but at the same time be sure that they can handle the effort and go faster if necessary.
I would opt for brushed motors from 7.2 to 12 volts but underpowered, therefore with 6 or 7.2 volt batteries.
This time however, given the dimensions and weight of the model, I would also consider the opportunity of installing a speed reducer (in this case I would use the right and not undersized power supply). I have no experience in this regard and I hope that those who have already used speed reducers for boats similar to this one can help you.

When I completely ignore the problem I do a lot of tests in the tank, considering speed and thrust, electrical absorption and temperatures. I recommend you do the same using engines you already have. If you see that they are weak, adjust accordingly.

Hermank sorry if I was very general but I have no specific experience on the matter and too little information; Nonetheless, I wanted to be helpful to you in some way.

Hi Ian, would it be possible for you to post a few photos of your Arun Class Lifeboat, as myself and others would be very interested, and even more so because of its size well over one and a half yards plus. This exercise should definitely do wonders to increase your street-cred. with a few likes. Regards, Gary.

Hi, i have a similar size lifeboat a arun class at 52 inches and powered on 2:- 500kv outrunner brushless motors, tornado tumpers from overlander batteries operating on 12volt nicad batteries, hope this helps , ian

And this is thé réal one!!!
