Hypertruck

[Zerobricks]

So after building raptor I wanted to try the other type of a machine. Something massive with RC motors for power and no signs of a diet

This is what I came up with:

It is the longest 4x4 i ever build thanks to the bulky RC unit. I tried putting unit on top of motors, but that made less stable. The suspesnion uses self amde links out of suspension arms (recycled from the failed monster truck project). The front axle is simillar to raptor's but uses different portal hub assembly for green wheels. The rear axle doesnt use H frame, because the 8+stop axles wouldnt fit in there. To transfer power from motors to both axles, i used two different ways. The front axle is wuite far, so a simple u joint combination worked fine. The rear axle needed a lot tighter and stronger assembly, which would also allw some shrinking and extending action. For that i used lots of pulley wheels and 3/4 pins.

Total gear ratio is 1:15 from 2 RC motors, and makes this machine unbelivably fast (capping 75cm/s).

Compared to the raptor its faster, but due to the long chassis and small steering angle needs a lot of room to turn. It also eats batteryes like there is no tommorow. Comparing these two is quite difficult. Raptor uses easy to get parts and is very efficient, while this machine uses rare RC parts and wheels, puts components under greater stress, but climbs better. I think i will use raptor for longer endurance trials and this beast for shorter runs, or rope pulling.

Which one do you like better, the slower more maneuverable and efficient raptor or this power hungry, not so maneuverable, but good climbing monster?

Here's a small teaser:

I like the Raptor better, because it has LDD Building Instructions , is lighter and more nimble, and uses parts that are within easy reach of the average Lego Technic fan. The Hypertruck is awesome, but if it has poor endurance, it may not do as well in Truck Trials.

Here is an update. I tried to make the body colorfull, because it really expresses the power of this machine.

Now that i tried it outside, i'm quite amazed how good it goes. The wide tyres provide excelent floatation on mud (too bad that cant be said for my shoes) and provide extreme traction with very deep profile. The only gripe is its length, which sometimes leaves it stuck on a pile, but thats a sacrifice I had to make. After 2 hours of driving it on mud sand grass, water and even pulling a car the tyres look like mini ecosystems full of various lifeforms

Here's a video of the truck. I think its the best lego offroader I ever built!

They are both great but I think I prefere this new faster one. You have a good balance between top speed and power, so it goes fast but can still climb. Excellent work sir!

Thanks! I reuploaded the video with a different song, because some users couldnt see it:

My vote definately goes to the hungry beast

I really like Hyperbeast. It's so colourful and powerful. Great job, I like the music too

I love the Hypertruck!!! It looks like a lot of fun with those tires and the super sonic RC system.. I wanted to get my hands on of those but it never worked out. It looks like with that much power that thing can pretty much go over anything.. Nice job! I agree with "VMLN8R" in saying that I like both of the songs that you uploaded as well..

@ Zblj: Do you think that your Hypertruck would work with some (doubled-up) 59521 "Lime Wheel Hard Plastic Spoked Giant Thin (160mm D. x 28mm)

" wheels? If you use four pairs of these wheels, they may get a better grip on mud, and go EVEN faster than the rare green wheels you're using....

Maybe for mud, but they are too plastic for everything else.

Bye the way instructions almost finished!

As promised, here are instructions in LDD.

Download them here!

If you want to use RC motors and the RC unit, you can also DOWNLOAD them here.

There are no suspension arms, and the rear drive axle has to be put together. Other than that no problems.

Enjoy!

I liked the failed shots at the end of the video when the wheel fell off.

It'd be cool with a Technic car that can dismantle itself. Like - you are driving around and you can push a button on the remote and all the wheels would fall off.

No, but seriously, something like that would be fun. Like a stunt car in Technic. Or maybe it has allready been done?

That's pretty darn cool. Thanks a bunch for the .ldd file. Very cool especially because of it being RF
