Hi Perkasaman2:

Thank you so much for your kind comment.

Hi Lou;
Exactly yes,I already have set it up the RC system in the very beginning before getting into substantial assembly of the ship.
But Martin indicated kindly above,I intend to modify the system from next week.
This is simply because I got recently a small and reliable pump for use with the cooling water to seek for an actual purpose and
scale realism to get the water out of the hull side.
And the present RC system is 3 channel and will be replaced with a 4 channel radio inconsideration of the actual operation at the sailing site.
1;New pump powered with 3V～12V though not yet tested
2/3;vey very old pump which I have felt something unreliable recently though Japanese-made.
4;Same type of pump(tiny yellow colored thing) used to work very much to circulate the cooling water with a 2 stroke 45 class engine even in the enclosed steel hull under mid-summer 40 years ago.!!

Hi all;
I started to modify the internal RC mechanism. Before that I detached 3 deck (hatches) from the hull first I had completed
as a plastic model ship to confirm if the decks were EASILY removed.....Only first deck(bridge and gun deck) was no Good as left-hand stairs down to the lower deck interfered with the left life raft.....
1;The first deck was detached and needs to adjust the left stairs not to interfere with the life raft...
2;Front life rafts of both sides needs to be easily detachable by some magnets for the convenience of smooth installation of the first deck.
3/4;The second deck was detached easily with no problem.
5;Thess two openings are enough to gain access to the inside of the hull.Though still lower deck itself is kept detachable with screws,but no need any more to keep it so.!
6;The third deck
7;Overview

Next is modification work to get her sail as a practically working model ship.!!

She needs more reliabilities and reinforcements to be a good runner on the water of our local lake.

Nice to see your progress Kiyo

You may want to place your radio receiver higher in the hull though. It does not weigh much and if it is placed high will not affect stability very much, but it will make it easier to keep dry just in case.

Hi Lou;
Yes,I do think so too,so that I have already set it on the white platform-deck as shown below.
It has been packed in a film bag for the water resistance.

Hi all;
The first water circulating pump I tried to install did not work at all. This is a Chinese-made one.

The second Chinese one worked so and so, and decided to adopt it aboard my Snowberry after brief modification to get it
work more securely to suck the water.
1; No good,d-.
2;This one is a bit better
3/4;Modified like this for a better efficiency to suck the water.
5/6;And installed like this.This one is so compact even for my small 1/72 Snowberry.
It did work in the bathtub test nearly at a standstill conditions. I gave it a OK since I will actually let the pump work at a bit faster running conditions.

"The first water circulating pump I tried to install did not work at all."

Kiyo...

If this is the pump shown in the first image?....it could be a simple el-cheapo $10.00 plastic housing gear or centrifical pump, which is designed to be installed with flooded suction - an example of this is the automobile windscreen washer jet pump, where the pump is located at the bottom of the water tank

These pumps will not self prime, they are also designed with the fluid medium for lubrication of the gear to housing interface

The second pump....is that a diaphragm design?

Derek;

I know that sufficiently and previously since the description of product indicated so,but at the same time it said Ok for the purpose I intended.

That's why I chose in vain. To make the matter worse,the pump did not work even for flooded suction purpose AT ALL.However,the second one is also intended for the same purpose as the first one,but worked much better than the first one,at least for my intended use.

Both are around USD12 made in China.!!

Hi all;
I set a main switch like this. I set here because it's actually only one and suitable place not to annoy me even if 3 decks were detached for some reasons,no wiring would follow the decks annoying me by the cords.

Moreover, this location I suppose will hardly spoil the important scale appearance..

I am so interested in how other builders of this model kit did with this point.....????

derekwarner · « **Reply #359 on:** March 21, 2022, 01:54:52 pm »

40 years ago, we would have said $2.25 each & made in Japan, however they would have worked with flooded suction

Backerther · « **Reply #360 on:** March 22, 2022, 03:57:55 am »

Hi all;
I made both front life rafts detachable using small magnets to get a smooth detachment of the first deck.
Without this work,it is impossible to detach the first deck.....

lmagna · « **Reply #361 on:** March 22, 2022, 04:43:32 am »

You may want to look at this switch or something like it Kiyo.
https://www.zepsus.com/product/magnetic-switch-15a/

The submarine guys use them to turn power on and off without having to open the watertight section of the model when they get to the running area. Just wave a magnet over the area where the switch is and power turns on. Wave the "Key" magnet over it again and the power turns off. There is no need for an opening or a direct mechanical connection to the switch so only you will know where to wave the "Key" magnet and there is no opening to wreck the scale looks or let water in.

Nice idea on the raft platform. Back when I built mine I just attached the entire assembly to the engine room casing with brass sheet and the rafts platform lifts off with the housing.

Hi Lou;
A great thanks for your new information on the splendid and sophisticated switch which I did not know at all so far.!!

The price is also priceless like its quality for me.!!

I will keep it in mind and my list of new parts to use for my RC models to come in the future.

My style of detaching the decks are possibly and nearly the same as yours....???
The first deck plays a service hatch while other 2 decks are normally kept closed.

Kiyo

lmagna · « **Reply #363 on:** March 22, 2022, 01:33:59 pm »

Mine is almost the same, except I do not use screws and I do not have the cutout hatch under the depth charge racks. I used silicone, (RTV) to hold the rear deck down in case I ever needed to remove it to work on the rudder. I have never had to remove it in more than 25 years. I have never changed the main deck but if I was to do it today I would hold it in place using neodymium magnets. Your system should work well and look good while running.

Hi all;
I am still using very old FM radios in my RC models and therefore set one of them for the Snowberry.
The long radio receiver antenna was set as in the pics below,which I think will be OK to get the receiver to catch the radio wave securely at the distance of 30m or so at the longest. Anyhow I intend to check the range test before the actual sailing of the maiden voyage.

I used a so-called glue-gun to fix the antenna around the hull side.

Hi all;

A report for today on my Revell Snowberry 1/72 is the cradles,one is for display and the other for transporting use..

1;kit version of display use
2/3;Modified one
4/5/;transporting cradle,this one is not special to the Snowberry...

Backerther · « **Reply #366 on:** March 25, 2022, 10:55:18 am »

Hi all;
Final smoking test was done at nearly completed conditions of the ship. ..So and so...If necessary,I'll replace with a powerful new smoke generator.

Backerther · « **Reply #367 on:** March 26, 2022, 07:13:38 am »

Hi all;
It seems that my winter project of building this Snowberry is being ended in these profiles.
I took these pics of so called two shot images with a package art in commemoration of the completion.

About 5 months have past since re-starting this winter project. All up weight for sailing is about 2.8kgs finally.
I am currently preparing for a launching and also waiting for the a good weather suitable for the launching.!!

The launching condition I am expecting is wind speed of less than 2m/s north...

Dreadnought · « **Reply #368 on:** March 26, 2022, 01:13:51 pm »

Looks great

Backerther · « **Reply #369 on:** March 26, 2022, 01:48:38 pm »

Thanks a lot ,Dreadnought !

I may possibly and happily be able to graduate from this column in about 5 months to enter into the Model Boating column at the very top of the this forum from April.!! ♩～♫～♬～

She is looking like a very nice nice addition to you fleet Kiyo. I will miss looking in on your progress. I will look forward to seeing her on the lake though. I also wish you luck in your search for fair winds and calm seas.

Lou

Backerther · « **Reply #371 on:** March 27, 2022, 03:54:07 am »

Hi Lou;

Thanks for your interest in my Snowberry and her maiden voyage.
Coming Wednesday seems so suitable for launching as the forecast has indicated it'll be 1m/s north during 6;00Am-12;00PM
which is the best for this class of model ship,if this should come true really on the water...

1;This is no wind fundamentally..
2;My Najade sailed like this on this conditions...not so interesting for this kind of fast boat.But rather good for a scale ship
3;From my experience of sailing on the water,I like this level of water conditions which might be around 1.0m-1.5m/s of wind speed...

derekwarner · « **Reply #372 on:** March 27, 2022, 06:22:57 am »

Will be watching on Kiyo

.....remember these vessels could climb 20ft waves

.....hope to see some video too

[you also have 16.6K views of this build here which is a credit compliment in itself

Derek;

I do thank you so much for your kind comment on my Snowberry.

Everything is already ready for sailing,yet the weather will be so important..
That is because even if the ship should stop suddenly on the water due to some reason,the north wind will surely assist me to get her back to the shore shortly and softly if it should blow at around 1.0-1.5m/s.....

In this case,of course, no recovery vessel is required...just wait for several minutes..

In this sense,around 1.5m/s of north wind is sooo expected to make a safe( if not successful) maiden voyage,in which no one could tell what should take place....

The following pics show the launching scenes of 1/96 HMS Fencer in 2018 June...Frankly speaking,I was a bit afraid of a sudden stop on the water because of no wind actually and no recovery vessel on the spot on the day.!!!!!

Anyhow safe return was done as a result.
