Suggestions : 1) trying to break the record with lego only parts. 2) trying the old exo force turbine : the blades are in both orientation, would be fun to see what happen with these. 3) testing the old propellers for technic planes ( there are different versions ) 4) trying with even more motors and propeller! Like 4 of them! 5) testing all the existing lego floating hull, from the very old ones to the most recent :D
Like a lot of people said, use a light gear ratio to trade some torque to some rpm. the 3 blades version is the most efficient (the 2 lacks surface and 5 constrain the water flow too much) so stick with it but try a bigger diameter or put 2 on the same axe (like 4 studs apart) to increase thrust. If you're not gonna use vanilla part then try toroidal propellers too. You can aslo use a rubberband as a pulley instead of a shaft to try to reduce drag under water.
@@LucasDynamics That will be the ultimate design challenge. I doubt it is possible using purely Lego parts but it might be possible using a Buwizz 3.0 as the power source. It could deliver enough power to archieve a power to weight ratio similar to pioneer era aircraft although there are many more factors to consider. Got a prototype yet?
Great video! Suggestion: Make the propellers lager in diameter (approx 80mm). The motors have enough torgue. And you will get less water disturbance. Cheers.

I reckon using larger propellers would make it faster. Since those motors you are using produce a lot of torque, you could put the gear ratio up or use larger props for maximum efficiency :)
Make 1 screw turn clockwise and the other counterclockwise. This gives you better control and you can steer with the screws alone. For more speed you can try to make jets
I built a boat this summer with the big blue ocean explorer hull with paddle wheels built out of the slightly angled Lego technic pieces and it was very fast. I used the standard motors and the standard power supply
My paddle wheels were much bigger too, for a more efficient power transfer. Propellers double the size of your current ones would make the boat even faster.
Whats the part ID for the submarine? I have never seen it before. Also, for more accurate speed, use a given distance and measure the time it needs to go that distance I would also try and only use lego parts for the boat and maybe play around with with the gear ratio to achieve an optimal velocity.
It can still be approved by adding more float stuff these things and bigger motors for power like an RC motor, but not too powerful or will break apart
You designed nice looking but inefficient propellers. They are used at very high rotational speeds since their profilenose eases into the water instead of having a rather broad line cutting into it at the same time. So you probably need three to five times the speed, to get the most out of your design. The size is really not the problem, they are well sized. But you might be limited by the maximum pressure and torque they can withstand. Also the pitch is not necessarily ideal at 0° in the water. It depends on how deep your propellers are submerged and how the weight is distributed along your boat i.e. the point of gravity.
It's not impossible for lego motor car to to match brushed motor car since I reached 34.2 km/h,but it will be way harder for boat since they have much more drag
@@rctv9974 I have set a new record for the fastest 100% Lego car reaching up to 20.5 km/h which is better than some brushed motor Rc cars. Because boats have more drag, add multiple motors. It should be able to get at least 30km/h if you are lucky.
@@Monster-st8hb I have reached over 30km/h at around 5 times using 6 buggy motors.And the limiting factor was not the power.I am currently fixing the stability issue.
And my lego rc car was faster than cheap hobby grade rc car with is wltoys a949,that rc car reached multiple 32.9 km/h and 33.3km/h once using the same bike GPS speedmeter I used into my lego rc car.The speedmeter model is XOSS G+ Any that rc car was fully stock,and it comes with 390 brushed motor.

Make a hole to trap the fish and maybe make a mechanism to alarm you of the fish Or! Make one to automatically reel it in with the fish!

This dude deserves a golden medal for his lego builds
Thanks man, appreciate it!
fr he does bro
Adjust the gear ratio for more speed than torque. Maybe it takes time for it to hit top speed but it helps getting faster atleast, I hope.
I will try this on the next one!
@@LucasDynamics Great😁 Ill watch it😊
Nice!
Tip: you can use bigger propellers 2: Add more kanoe looking thing so it can cut through the water and be more faster 3:add more propellers
Great Work Lucas! I cant wait until your next Video/record
Thanks man! Working on it already!
Try using 4 motors.

See if some sort of lego hydrofoils can slightly lift the boat for reduced drag
Intresting idea!

Add some gear ratio onto it, it will make it faster. Try putting an 1:3 gear ratio so 6x3=18kmph

What do you mean?
suggestion:
1. add a big hull in the middle, just like the lcs warship from us navy
I will ad at least one more!
Good idea
Thanks!
Woooo yeah baby
The one thing I can recommend is lubing the joints to reduce friction
True
And also, you mostly only focused on the bottom of the boat with the engines. I think you can make the front more aerodynamic to make it a bit faster
It's not fast enough to be caring about the aerodynamics...
@@LucasDynamics oh ok. I should maybe trust the person that knows about Lego boats more than myself 🤣
randomly stumbled upon your channel now im hooked lol your a smart kid man keep it up! love the videos

Use a 3d printer to make a motor mount for DC motors and use a flight controller for extra speed agility and lightness.

The lest material underwater the better. Maybe use a 3d printed boat for less drag. DO NOT USE PLA IT MELTS UNDERWATER
What, why? Does Pla Melt in water? I don't think so but I could be wrong.
The propellers I used for this video are made with PLA... They did not dissolved 🤷♂️
@@LucasDynamics dissolved?
@@LucasDynamics just dont make a pla boat and expect it to be durable
@tremplador True, so if I use ABS it's ok? 😏
Make it wider and add 5 propeller 😊
prove tesla wrong by building a better car than tesla *WITH LEGO*
Make a 1:1 scale Lego boat and put a 90 horsepower motor on it

Cool vid but what took you so long 😬
Thanks!
*No comment on the delay...
Try and create a lambo in lego! (use the strongest battery for the engine and the strongest motors for the tire)
wow very cool from a normal boat to a jeski thats 100x faster
Thanks!
Wel some gearing making more cranks or rotations could make IT go even faster

What would happen if you put a real motor in a lego boat lol
@@Chick_Wilson2011 It would go way faster!

To reduce the drag even more and add another motor
2:33
You shutted up powerful cars sound with that motor sound
you could just place the propellers behind the 2 floating boats that way no drag created
Those motors have two speed ports make sure you use the faster one
I used the faster one!
Maybe try adding a third motor and a third propeller
I will use 4 next time!

Use four motors instead of two

I definitely will!
@@LucasDynamics would you make a video than?
Yes, not directly, but in a half year, probably...
The nose of the boat goes very pitch down
True, I will make it differently on the next one!
And the propelers Don’t have much trust so if it floats more it can slide along the water
Make an Lego car but use the vacuum engine

Great work! I had to stop watching because of the lighting of your builds. The light-dark background created a strobing effect when sped up.

My son says add more motors and a more hydrodynamic boat
Greetings to your son! I will double the motors to 4 next time!

Thanks mate!
Why don't you use gear ratios 2:4 to increase the speed ? Does the motor havn't enough torque ? Its seemed under used.
