Making a Fast Lego Boat 1/3 - airboat

Building a fast Lego airboat - a boat with aircraft-type Lego propellers. Only Lego parts are used, except for BuWizz 3.0 battery box. Enjoy!

More details in my blog:

You could try turning the left propeller clockwise and the right propeller counterclockwise.
This creates an air cushion behind the boat and could increase the efficiency a little.

You should put a vertical stabiliser on it, underwater one like a rudder. It would be more stable in a yaw axis and you wouldn't have to do so much inputs keeping is straight.

5:11 When I was in college, my roommate, an engineering major, got his hands on a remote-controlled canoe and decided to upgrade it. He installed a high-speed 11, 000 RPM motor, fine-tuned the balance, and even experimented with different propellers. The first few runs were incredible—it sliced through the water like a bullet. But then, he pushed it too far. The motor overheated, the hull started shaking violently, and before we knew it, the propeller shaft snapped clean off! The canoe spiraled out of control and sank right in the middle of the lake. We couldn’t stop laughing. Ah, college memories!

I admire your level of technical knowledge, as always. But what absolutely amazes me is the fact that you were paying attention even during the test drive and did not endanger any water lilies. Hats off, sir.

Never miss an upload, best lego channel out there

Next Lego boat will have a Lego saw to remove the fallen tree in the river.

Imagine you're taking a hike through nature. You get near a river and you see lego boat gliding across. It might be the strangest thing you see that day

Edit: Da fuq happened in the replies?

after that submersable, you sure you should be using a game controller?

This reminds me of the airboats used in Louisiana and Florida. The difference is it's one fan and the steering is done by putting a rudder on the back of the fan instead of the water. They are flat bottomed, shallow draft boats, as they're used in swampy, boggy areas, like the Florida Everglades.

Much simpler than the submarines or the drone, but a lot easier to maneuver and control. Sometimes the old way are better.

6:26 Great places for fishing! Are there predatory fish in this river? Have you tried fishing here?

A Keel and rudder would help tremendously with the boat veering left and right

At the end of the series, you should do one where you just strap a model rocket motor to a lego hull and stand back.

I like the troubleshooting and experimentation stages of these videos. It's nice to watch things iterate and improve.

They really need to do another set with that giant cargo ship hull. The original was awesome, wish I hadn't used it for parts as a kid...

[Marines_Memelevolent]

I enjoyed watching the gradual evolution into the air boats I’ve been seeing near all my life lol

[MadamLava]

Great! Now I can finally defeat that Combine Chopper and make it to Black Mesa East

[jdbrickcreation]

Waw, it's crazy to reach that much speed on a boat with legos 👍

[LBJHJP]

The biggest hull will always be faster unless you can get the boat on plane. Also to go straight put a rudder in the back, even if it is fixed.
