Here I present a few more interesting sketches of paddle steamers from Central Africa.I tried to color something.I have read that this type of ship has an unusually raised bow, mainly for overcoming waves over the bar (at river mouths into the sea.)

Allesandro ,
Even our little Bečva can sometimes be big... even bigger...

Some pictures from the construction of my Lulonga model.
I found this plan on the internet.. I put it here as info( source unknown..) If anyone is interested in building this model, I recommend increasing the length of the model by at least 4"-8", due to the longitudinal balance of the model and directional stability.
I simply did the centering and alignment of the paddle wheels by pushing a long steel rod with a diameter of 4 mm through all 4 bearings, and only then glued the bearings in place. Then I could use split axles (Ø 4 mm) , for each wheel separately. I used a toothed rubber strap to transmit the movement from motors.
Due to the model speed, the paddle wheels (Ø140 mm) have a resulting speed of approximately 100 - 120 rpm.The hull has a simple box shape with a rounded bilges.

I found another modification of the ESC connection in a model with an external mix.
As I wrote, I normally have the rudder control on channel 4 on the Lulonga model, and I only control the direction with the motors. Even so, the model is unusually agile and can turn almost on the spot. But I think that for classic sidewheel steamers, this connection with the connection of the rudder servo into the mix can additionally increase the maneuverability of the model.

What do you think about the model >> John Fitch rowboat< ?

This American inventor invented this method of propulsion even before the invention of the ship's paddle wheel
You will find a number of interesting links on YouTube and the Internet.
An article about this model was published in the magazine > Marine Modeling International < , September 2013, under the title "The Beast". This America´s first power boat was a 34-foot craft,model is 5 feet long, about 1 foot wide and 6" deep.

​Look up details

something for paddlewheelers fan>a slightly different other steamer..

Hi Allesandro,
it's too many questions at once.
So - Lulonga has a rudder (for me on channel 4) but it is placed under the inclined stern, and it has been tested that it works only with little efficiency, so I practically do not use it.
Location - I live in a small town Rožnov pod Radhoštěm, Czech Republic, Europe. The river Bečva flows through it. It is, as the experts say, a mountain-type river, for you it would be more like a stream.. We were here on the river with model Lulonga > 49.463001, 18.147153 The first photos - the lake in the park with my Capricorn model, the last photo - I think it's the place in Bečva where we were with model Lulonga.
I also run model boats on the small lake in the park, which is a little bit next to the footbridge. I have no other choice at present.
Angled Paddle Paddles - I covered this in detail on www.Paddleducks.co.uk which is mainly for paddle steamers. In the original, the inventors claim that wheels shaped in this way have better maneuverability.
