Hi tica,


I'm so happy to have your comment of compliment on my post.!   
I have attached the video of the sailing which represents the trial run clearly and vividly rather than still images.
The boat ran so fast that camera woman and camera was sometime unable to follow the boat, by which some scenes
were terribly bad to see...even the Panasonic video camera warned the camera woman "too fast to move the camera"..
The largest and initial impression is that she ran so calmly even at high-speed so that motor sound could be hardly heard
in the video even when she passed the shore.  Due to the calmness of the motors, this boat seems hardly to represent powerful impression as compared with the high-speed capability.....

It was tooo hot for mid-winter around Tokyo !!!! 17degrees C !!!!
Yes, of course, I went to usual lake to enjoy the sailing of PT-109 who has spent a long time not on the water,but on her
sleeping bed in my room.
The wind was 0m/s south-west which I dislike since it normally carries the dirty substance as seen in the pics...
To make the matter worse, such substance is apt to be a terrific cause of accident to the running boat at speed....

In the second run this day, suddenly mishap occured to the PT-109 as seen in the pics below !!!
Something in the water might have stricken the starboard screw props in the high speed run...oh my goodness !!
I noticed the loss of the props after recovering the boat safely as port side props was running normally though entangled by
the dead grass....


1/2; Starboard screw props lost in the water when sailing.....!!!!
      But the coupling was quite OK.



3; Only a few drops of water could be found in the rear compartment due to my style of water-tight measures..
  Oh,don't worry about the screw props lost.
 I have still a pair of the props CW and CCW  for fear of such an accident.  
This is the military model boat actually in service.

It was really a breeze to replace with a pair of new props. !!
All that I did was to enlarge the holes of props to 1/8 inch (3.17mm dia.) and installed them to screw shafts.
This is a military model boat that must be easy to maintain or repair in a usual operation.!?


1;Only starboard props were lost but both props have to be replaced at the same time.!
2;Spare props in stock
3;Very very special nuts of 1/8 inch size here in Japan!!!  This model kit is made in USA in accordance with the US standard.
   Screw shafts were furnished in the US standard and I had to buy unusual size of nuts additionally for my US-made kits
later on.
4; Right one is new props, the rest is old one.
5; Both screw props were replaced in a breeze.!!


Well, let's go for boating again in a very fine weather with clean water.!!!!

Hi RC boaters,
It's really hot with 30degees C here in Tokyo that means completely water season and may be the best or the limit season for
RC boating outdoors since it will be normally get to around 38 degrees C in the mid-summer even in Tokyo.
In such circumstances, Allen A seems to have started his PT boats shake-down sailings recently by which I am affected greatly to lead to getting my PT-109 on the water as seen in the pics below.!!


1;It's the best season to operate the Rc boats?  not soooo hot...
2/3/4/5;" Go for the mission, Kennedy, attention to enemy destroyers !?"
6;"Welcome home safely after the glorious mission in 「the Pacific ocean」"


A provoking problem standing just in front of the Rc boat sailing here in Japan in these days is its peculiar rainy season to start
from next week through late July, after which it should normally begin really hot mid-summer reaching around 40degress C across Japan.

I have checked my PT-109 if she should go well since it is a long while after the last sailing on the water taken place on last Feb.
Nothing irregular or abnormal has happened with my ESC QUICKRUN 880 brushed(not 1060 type) that can control two motors.
He should possibly have adopted this one rather than 1060 type as 880 type was soo easy to set, just plugged in among ESC-RX-motors and could go practically automatic...


Pics below are my initial set-up of the 880 type which is much powerful and simpler to set than 1060 enough to run two Mabuchi 540 motors at full throttle as seen in the pics below.
This set-up with the 880 type ESC was succeeded to the next project of 1/20 Lindberg Chris craft Constellation as it had been
in the PT-109 as in the last 3 pics.   
Simple, safe and secure to install in the Rc boats which is sooo important to sail on the water, especially on the lake as we use in the pics below.
