Apologies for using KM/H if you prefer MPH! The reason for doing so was to have more definition at these very slow speeds as my GPS doesn't show decimals. Here's a conversion to MPH of the final cars in each class (spoilers below)...


Pure Lego Car - 7mph
Rocket Car - 23.4mph
RC motor Car - 26mph

Thanks for watching! Will be back soon with another video (hopefully within the month) ☺

I bet if he and Brick Technology teamed up they’d make something absolutely insane

[MarijnRoorda]

Perhaps you could partner up with someone who is more versed in building with technic lego. For starters i could see a use in suspension to offset the bumpy roads you use, and a wider track for higher stability. And there are much better wheels available in Lego. And perhaps a gym floor would be better suited as those are typically fairly large and exceptionally flat and smooth. A indoor location would also rule out weather conditions.

I bet you could find a way to seal off the floor of the car and add a LEGO fan to make the car go even faster

[tomsoo]

Honestly would have liked to see a bit more restrictions/rules as it does seem like you could have just stuck a lego brick to your existing rc car at that point and called it a lego car by how some of the final ones were propelled. It seemed less about optimising the lego part and more about building the most basic chassis and sticking a rocket on it.

[winddk]

You can definitely optimize your lego builds to make the car a LOT more stable

[henrywood]

The thing I like the most about your videos is you show all the fails and problems you have with the project

[hyperturbotechnomike]

What your lego cars need is suspension. The Channel Brick technology has made a video where he compares different types of lego technic suspension designs. A differential would also help against wheel spin.

48 years ago, using the same rocket motors, Estes C6-5, my friend and I built a Lego rocket car. The car disassembled in rapid fashion on the first three attempts. However, we discovered using Large Lego wheels, 2" in diameter with a 1/4" wide tread, and lengthening the vehicle to about 2' long AND using a new invention called Krazy Glue. We had three successful runs. Using a stop watch and a blacktop basketball court to measure speed, Lego Landsmasher IV went an astounding 26mph.

Tether car that goes around in circles tethered to a central post would be good to try also. There used to be a guy that brought a whole set up to Old Warden model days with some high speed petrol engined tether cars running on a circular portable road - they were quite exciting to watch.

[themetalslayer]

there's 2 improvements you can do
first adding suspension to help the car to keep its wheels on the road (it will increase the weight, you'll need to take care about the suspension travel and lego shock absorbers aren't the best but it will absorb the roughness of the road and will improve the stability)
two : don't forget to put a caster angle on your steering to improve stability
the vehicle is very light so the stability is really important

1:54 "kp/h" is wrong. Either "km/h" or "kph", the "p" stands for "per" and thus makes the "/" redundant.

[Nathan]

11:45 So much torque, the chassis twisted coming off the line😂

[tofu_golem]

The one using LEGO parts entirely was the most impressive.

[AccAkut]

The 3:30 variant reminds me of the "Dolmette" chainsaw driven motorcycle 😁

The last car just had no chassis at all, you basically just bolted two axles to a flimsy wooden board. Just with some simple chassis building, triangulation and so on you'd have a car that survives the stresses.

[th_St_Air]

You certainly achieved the “Air” part of the project here @8:07. 😊

[BrixDownUnder]

bro just looking at this makes me cry 3:10 there is such a tiny fraction of current going to those motors. Also people have made genuine LEGO cars that go faster

[nigeldepledge]

All of your cars were pretty flimsy. If you don't mind adding quite a bit of weight, you can make them much stronger.

However, the surface you're running on will always be an issue unless you use suspension.

[kaiperdaens]

Yeah so that much Lego motors should definitely go on different battery boxes and different ir recievers BC you were overloading them, and definitely if you want speed or power.
And you probably don't know but the different motors have different speeds and powers.

[alwaf]

When making Pure LEGO RC Car, I highly recommend BuWizz Motors, especially the 3.0. Because, it has atleast 5 times more power than the LEGO Motors you used.
