Hi ScottW;
So glad to have your kind comment.

Over the rough waves to the goal of a wonderful RC boating.

Hi all;
I fixed a main switch on the stb deck making use of the original location already opened ovally.
1;A switching rod installed.
2;A waterproof rubber attached to be installed inside the deck.
3;The rubber and switch were fixed inside the deck.
4;A suitable amount of grease added.
5;And coverd the switch hole.

This will possibly allow me a better result of waterproof function.

The next is the bilge keels.

Backerther · « **Reply #52 on:** August 14, 2022, 06:48:10 am »

Hi all;
And done like these with the bilge keels.

Well,what should I do next..??

Painting will be the case,perhaps..

Maiden voyage would be on coming mid-September or so..??

All crews quarters right away.!!!

Hi all;
A little progress of balancing adequately this PT-109 on the water was made finally at this time.

I tested the boat in the bathtub 8 times to decide which waterline would be the most suitable and scale-like to my personal image,often referring to many information in the internet.
And I decided the line as in the pics below,though which is possibly not correct to precise scale level,but I don't care for it.
More important points for me are well-balanced sitting on the water at calm wave and real running characteristics.!

1/2/3;Water line decided based on these pic for a final plan
4/5/6;Final layout of the radio gears to float the boat maintaining the waterline as above.
And CG could be expected to be lower a bit by this new layout as well.

At this time,nothing to do any more except painting..but it's still too hot to paint outside my hobby room...

Backerther · « **Reply #54 on:** September 11, 2022, 11:14:08 am »

I could find a nice day for painting at last yesterday when was not so hot but a bit windy...
I have beeeen waiting for such a day for a long time.

I just applied only 4 coats of primer surfacer this day.
I then sanded smooth the surface of the hull with #1000 grit water paper today.

I made a ducted painting "device" with a fan for single use from a cardboard box to be abandoned.
The purpose is, of course, to use for air brush painting of my PT-109 boat.
The device is sooo humble and simple but useful for me for the above purpose.

1:The device!
2;With a skylight

3/4;With a ducted fan to drive sprayed paint mist outdoors
5;Set like this in the room
6;Viewed from the outdoor
7;Now,shall I start the airbrushing ?
8;Some assemblies were done without being annoyed with the spray mist.

However, unprecedentedly tremendous tyhoon is coming over Tokyo in a few days,by which it has started raining.
The painting work is postponed as fars as later this week...

ScottW · « **Reply #56 on:** September 19, 2022, 06:26:10 am »

A nice bit of practical creation there.

Since I've not been watching news for a while on account of having messy health I plugged Tokyo typhoon in to Google.

Daaaaaang!

I think it can safely be said without hyperbole that y'all have a serious situation over there.

Found this, https://www.jma.go.jp/jma/jma-eng/jma-center/rsmc-hp-pub-eg/RSMC_HP.htm

And this, https://www.japantimes.co.jp/news/2022/09/17/national/typhoon-nanmadol-rapid-intensification/

Quote

“If the storm maintains this intensity as forecast, it will make landfall as one of the top five strongest storms to strike western Japan on record,” said Robert Speta, a typhoon expert who previously worked as a meteorologist in Japan. He said Nanmadol was the strongest tropical system anywhere on the planet so far this year.

Thank you for your comment.

I have fundamentally finished to paint the major structures as seen below.
The next is the hull which will be done after the tremendous typhoon....

Backerther · « **Reply #58 on:** September 28, 2022, 11:19:39 am »

Two-tone color painting which was peculiar to the PT109 in the Solomon theater was fundamentally done.
I just only put the major assemblies aboard the deck. Oh, really looks so dirty like the real PT109??

I just don't feel like to add weathering works on it as they have been done already....

Backerther · « **Reply #59 on:** October 10, 2022, 11:51:30 am »

General assembly is fundamentally over with these pics.
However, some detailing and more weathering painting as well as rigging works are still left to do before the maiden voyage.
Oops, indispensable 8 crews have also to be added before the sailing.!!!

Simple two-tone color painting is rather difficult for me to represent realistic image of the boat as it is apt to get monotonous.

Backerther · « **Reply #60 on:** October 12, 2022, 11:28:12 am »

And I applied a simple weathering paint job to save light impression of the hull.
But to my regret, it appears to me that the pics don't show the actual impression of the model...

I have watched the movie of ”PT109” frequently for reference of coloring and followed it partly.

Backerther · « **Reply #61 on:** October 16, 2022, 11:35:34 am »

The skipper shouted suddenly with a binocular in his hands:
"General quarters!! General quarters!! Jap Zeroes diving into us at one o'clock high south! Right away, right away!"

Looking great

I'm hoping to be back in the workshop soon, to proceed on my PT109 1:20

Backerther · « **Reply #63 on:** October 17, 2022, 02:33:24 am »

Hi tica;

Thanks a lot for your kind comment.!!

I also have been following your posts on larger 1/20 Pt109 boat.!!
I suppose yours will do a very good job on the lake like the real PT109.

Kiyo

Backerther · « **Reply #64 on:** October 17, 2022, 11:04:04 am »

Simple and brief detailing was made on the operation panel and wind shield frame.

Backerther · « **Reply #65 on:** October 18, 2022, 10:41:20 am »

A little progress but important and indispensable for today is this support for the main mast.
This part has not been supplied in the kit...but a comparatively large part around the main mast.

Backerther · « **Reply #66 on:** October 19, 2022, 03:26:00 am »

This summer-autumn project that has started on previous July 2 seems to be approaching final stage.
I may be able to have a chance to make a long waiting maiden voyage in coming Nov. at the latest.

As this project is intended for RC conversion of pla-model kit of MTB PT109 for the sake of sailing on the large lake.

However, it is true to say that more the project goes on and on, more I do feel to add further detailing work on her...
This kind of feeling will sometimes invite endless-like work for me who is what I call "a RC model runner" rather than a true RC model builder.

Pics for today are simple works of rigging, railing and numbering.

Backerther · « **Reply #67 on:** October 21, 2022, 09:48:59 am »

My PT109 is securely approaching the day of maiden voyage together with some little detailing works day by day.

Some of the evidence for today...

Backerther · « **Reply #68 on:** October 22, 2022, 05:36:49 am »

My PT109 is flying newly added the Stars and Stripes proudly on the mast as if all were up for the maiden trial run..

I feel that this kind of flag will do a good job to generate some kind of scale realism for the model ship, especially simple war ship like this...

In these pics, the comparatively colorful flag is really eye-catching in a monotonous colored hull.

However, to my regret, cal.50 machine guns are not ready for service with this condition...

Backerther · « **Reply #69 on:** October 23, 2022, 03:46:02 am »

The pics for today are the indispensable items for the cal.50 AA guns, YES! they are the ammunition belts.!!!!!!

Two gunners are posing with the hands on the handles of the guns without ammunitions, looking up to the sky...

These poses are surely something strange and contradictory for me who does never want to ignore such condition

Therefore, I made very very simple and brief ammunition belts that may look the stuffs at the distance over 1.5m.

These ammunition belts I think may be much better than nothing with the machine guns at least !!

1; Something strange and contradictory...no ammunitions
2;Making use of stapler needles applied with rubber related bond to avoid the separation of each "projectile" while giving them some flexibility as the ammunition belts.

3; Cut to shape
4; Simply painted them and simulated ammunition belts are now complete.

5/6; And set the ammunition belts beside rear machine guns.
7; Front machine guns.

That's all for today.!!!

Good Mod, have you retested the waterline and stability now the crew and detailing has been added ?

Backerther · « **Reply #71 on:** October 24, 2022, 01:02:02 pm »

Hi warspite;
Thanks a lot for your kind comment and a good question always to the point.!!

Here are the latest pics of draught line, which I think is so so.

The last two pics were other modeler's ones(Lindberg make).
I think at least engine exhaust pipes (holes)at transom must be over the water.!!
Sailing stability will be tested in the very near future on our local lake.

Kiyo

Backerther · « **Reply #72 on:** October 26, 2022, 06:52:09 am »

My PT109 is actually complete with these pics nearly as per the kit instructions.

All up weight with a Lipo battery(0.27kg) is about 2.4kg (5.3lb).
The last pic shows the main switch which is of course completely waterproof.
This summer-autumn project will be over when the boat should result in a good sailing performance as a RC MTB on our
local lake, which sailing test may take place in the very near future.!!

However, modifications and improvements will possibly follow even after the maiden voyage until I may feel that there is nothing to do any more concerning this boat. At this time, she is literally complete, and the project is fulfilled..!!!

Backerther · « **Reply #73 on:** October 27, 2022, 01:30:01 pm »

I reviewed the water line and battery location to prepare for a high- speed sailing of this PT109 in the maiden voyage.

Stern became a bit shallower while the bow a bit deeper.
The battery location went down to the bottom of hull for maximum stability in the sailing.

Backerther · « **Reply #74 on:** October 28, 2022, 07:38:30 am »

Hi all.
It was rather windy and cold day on our local lake for maiden voyage, but I couldn't be luxurious as to choose the best weather
for RC scale boat 1/32 especially in this season....

It's too normal for the wind to blow at around 3 m/s or more (11km/H) here in this season which is rather rough and hard for 1/32 MTB to sail very first and safely...

My Pt109 looked just as if she were sailing in the North Atlantic Sea in the mid-winter, though I have never been there so far at all.

Well then, the theme for today is as you already know maiden voyage of my PT109 1/32.
1; Set out for the maiden voyage in the rough water or I should say it trial run rather than maiden voyage...
Water drain looked OK though even at a low speed.

2; The Bilge keels I added for RC sailing seemed to have made a nice job in this pic at high speed.

3; Even at low speed as well.

4; Draining was also good at low speed.

5; So dynamic in the rough waves and stable to maneuver.

6; Set on to dive into the water like a sub.?????

7; This time, on the contrary, like a flying fish.!!!

8; Both draining and bilge keel-effect looked OK.

9; The task was nearly fulfilled under the hard conditions, and she came home safely and slowly.

10; "Hey, you did a very good job in the rough conditions of the first trial run".

The 3 minute-video will follow in the very near future.!!
