another Lulonga model

[Tomas Krejci]

Hi,
     Today Lulonga River  steamer passed further navigation tests after replacing the ESC.(the new ESC are from HK...), working well,
The electronics work reliably, problems with stability again, but this time with a transverse stability. Since the superstructures that I built are quite heavy, and the model also has a flat bottom, so setting up a balanced position is very sensitive, and somehow I can not.
I try to stick around under the bottom of the line model, additional load.
Perhaps it will also help the exchange wheel (see previous posts).
illustration, there are links to youtube.
I had a good cameraman this time ...

Looks great Tom.

Thanks, Damien..   

some more Lulonga  photos    (also other than the model) can be found at

It seems to me that Lulonga River quarterwheeler  will employ me yet for a long time..anyway...

Hi Dererk,
                  a link to my video has been placed here on August 02, 2015, 11:19:05 PM
                  with link to my photo albums at Rajce anyway.
       At present I build Thames sailing barge model (1:24)...another ship of unusual constructions that interested me.
   (  http://barge.homeunix.org/index.php/home   ...   I am here by the nickname tomarack (Tomas Tomarack)).
         Then maybe Clyde puffer.. when my health and the stars will be  favorable for me...

Tomas...[grandpa to be] I have gone back and can only find reference to the sound system in reply#35 on 29th May ...what type is it?......and adjustable?.... sounds realistic and loud  ...

PS... [I have seven grandchildren].... .......Derek

Hi Derek,
               for the steam engine sound I have "homemade" unit , which is ( as I believe) based on Arduino . Arduino is an open-source electronics platform based on easy-to-use hardware and software. It's Intended for anyone making interactive projects) .The unit (sound module)I bought from my colleagues who dealt with it sooner, fog horn from Robbe and siren 12V designed for electronic devices .. not much .. but buy it .. (just under 2 dolllars)..
Loudspeaker 8 ohm from pocket radio, for foghorn loudspeaker Ø 10 cm(4")due to better transfer of the low tones .
It seems to me that the volume of steam module is too large, but at the water is just right .. Another friend of mine told me that (according to him), "steam engine" runs too fast .. but on the other hand it  beautifully reacts to every change the speed of the model.
I had but in the back superstructure made  another open portholes  and open the side glazed hatches,(rather  straight breaking glass), because the "machine" was not in the first phase of tests ever heard. The recommended version with sound of foghorn routed through an open stacks didn´t work properly .
So..   Derek .. great-grandpa ... and it will not apparently better..      
greetings   Tom

Hi..

          some of last videos ..please .. if you look at   >   https://www.youtube.com/watch?v=T-GNZ3Qzq1A 

 Lulonga in park pond...I would like to add yet
 as I wrote before.. Lulonga  is controlled by changing the speed of motors via V tail mixer (Rx canal 1 + 3) The rudder is sorely  ineffective( canal 4)
 because it is overshadowed by improper construction  stern design and additionally placed in the wake of the wheels.  .
On the other hand,she can turn almost on the spot ...as you can see.

And what next.. as  I wrote..Thames sailing barge and next... maybe John Fitch Rowboat .. for big fun

Wonderful model Tom I'm really impressed. 

[derekwarner_decoy]

  Tomas.........yes she responds to the helm [steerage] very well indeed in both Fwd & Astern......many steam paddlers had gearing between the engine crank and the paddle shaft, so to me the sound could represent this as opposed to a direct drive.......I do like the steam engine sound and volume

There is one question....in the video between 3.01 to 3.08 we hear a ratartatat.....noise...is that a floating twig caught in the paddle box?

Congratulations......  ... Derek

Hi Derek,
               the steam sound unit makes S S S S S only,with accompanying copiously splashing  sound 
 from paddles.
This rat rat rat..This pond has around trees, and the water is a lot of leaves and small twigs ..and lots of wild ducks...
The gap between the wheel and sides of paddle boxes is small, and so the wheel got stuck a few times when the dirt got there . Usually it helps reverse moving of paddle wheels, in some cases the model must come from the water.
As I read , the great steamers on Murray River have  similar problems with  floating tree trunks and branches of trees.

Hi gents,
              I was able to go with the model Lulonga  to the water again,with  the smallest member of our scout troop, but this time at  the river Bečva.

Posts can be found again on youtube too.
