[MOC] Racing Boat

[KirTech LAB]

Hello all!

The summer isn’t ended yet so I want to present summer model. The title isn’t entirely right because I’ve met very strange problem with RC: RC-units received strange signals and motors turned on and off without my commands. There is a granite mine near the filming location so maybe there was some interference. But it was rather funny to play with this MOC:

Now I’m thinking about S-brick but new version of this MOC will be ready to the next summer most likely.

Thanks for watching!

That looks pretty good, and performance isn't half bad either!

Do you have some pictures of the more technical sides of it?

[Awaken_M1nd]

Amazing work, dude! Waiting for next summer and version w/sbrick.

Cool MOC with good bodywork as well. Out of interest, how many RC motors/units did you use and what type of propeller?

[MajklSpajkl]

It really looks good, very nice cover of the hulls. So what did you use for propulsion? It looks like a long technic axle... doesn't it bend or fall apart?

[Graham Gidman]

Most impressive!

Thanks for comments! BTW: has somebody met such a problems with RC units?

I'll add a few detailed pictures late. To say the truth the transmission is very simple - just a few gears to connect motors.

I use two RC-units and four buggy-motors. Four blades are mounted at the end of each driven shafts:

I know that these propellers are not ideal for water but the main problem was not in blades but in RC interference.

lol..... I love that you had to go out swimming after it.

Great job! Lego definitely need to develop the direction!

At first they need to create unsinkable hulls and waterproof electronics.

Awesome boat ! At first look it looks like a real one :thumbup:

has somebody met such a problems with RC units?

I did had that problems but with the Outdoor Challenger on the third channel( the same antennas and controller as normal RC unit)

Sometimes I first lose the signal and than it goes by fits and starts(рывками) and the steering makes the same but from side to side.When I reset the RC unit it works perfectly.

Excellent work. Great design. And a beautiful background. Who swims faster? Boat or author?

[Blakbird]

Fantastic video. Makes me wish I was there with you!

[KirTech LAB]

Thanks for kind words!

I've made test video about the mechanisms of this MOC. The original language is russian but I've made subtitles as always. So I'm very interesting in your feedback both about mechanisms and such type of movie.

Thanks for watching!

Great video of your racing boat how it's works. :thumbup:

[BusterHaus]

Haha! Swimming to get to the MOC - that's dedication! That's a very entertaining video.

As for the reception problem, it may be a result of the antennas being placed horizontally. Certain antennas are designed to be operated in a specific orientation, and placing them in a different configuration affects their performance. I'm not sure if it's the case with Lego RC antennas, but I would try out the motors with the antennas placed vertically.

Очень здорово, поздравляю! 3.000 оборотов - это почти вертолет взлететь может ;-)! Да, жалко что лето кончается...

Translation: Very cool, congratulations! 3.000 revolutions p/m - almost a helicopter could lift with ;-)! Yeah, it´s a pitty that summer ends...

[LEGO Train 12 Volts]

Absolutely outstanding!

Beutiful MOC and amazing summer location! :wub:
