The Arrow

All have a nice day!!!

I want to tell you about my current project – 1 : 10 RC model of the SuperCar from “The Fast and The Furious 6”!

Its total size – 52 x 22 x 9 cm.

Weight – 1.5 kg.

So, what do we have?

First of all the the model is really fast due to two powerful Race Buggy motors and new V2 IR Receivers, and now I am working on the replacement of the rarity Buggy motors by new L-motors without speed loss.

The main model’s feature is independent front and rear steering. This feature makes the car super-maneuverable!

The model has AWD with three differential gears and full independent suspension.

There are three sets of LEDs under safety cage arcs.

Fake exhaust system:

All features you can see here:

Thanks for watching!

Cool model. Independent steering sure looks like fun!

[Someonenamedjon]

Great job on the independent steering! Could you show us the underside with the black panels taken off?

[spzero]

thats genius

The model is really cool, but I'm surprised to find anyone still putting much faith in Cuusoo. Sad facts are:

- five submission were approved over SIX YEARS

- no Technic-themed submission was ever approved

- if memory serves me well, the largest submission ever approved was like 400 pieces altogether

- a submission can be very different from a resulting set (e.g. Back To The Future deLorean)

I'm having to agree with Sariel here, this is an awesome model but you're wasting your time putting it on cuusoo imo

[tbird8057]

I agree here about Cuusoo. I just wish TLG would clarify whether they would even consider a technic submission. With already having technic challenge I would accept the fact that they aren't going take any technic through Cuusoo, I would just like to know one way or another.

This is awesome! I just watched the movie, and I so want this model to try out! The dual steering looks great and and altogether goes really fast!

I too would like to see some more detail pics from inside!

Great job. :thumbup:

[Lakop]

Brilliant model! I love the four wheel steer and suspension but would love to see the underside and it's workings. Good design also.

Id'd like to see this made into an official lego model,the bodywork is what I like best of all, and all wheel drive/steering/suspention is a nice feat for lego technic.

Those buggy motors are way faster than any other lego motor shame lego dropped them.

Thank you!

So, you'll be disappointed if you see technical stuffing - it is really primitive!

Here there is transmission (not in scale - just for illustration):

I considered several variants of steering mechanisms, but the most reliable, fast and compact was just put two servo-motors.

First of all thanks for positive opinion! Of course, you are right about Cuusoo! But with Cuusoo or without - this model is excellent platform for some new ideas proving. I want to try L-motors and new motor connection way that gives even more power than V2 receivers (at least i hope so :) )

From your drivetrain, it looks like there is some tension or tires slipping, because it's AWD with wheels of various sizes, and without a central differential (instead, you have an adder in the center). Basically, you're driving all the wheels at the same speed even though the rear ones are bigger than the front ones.

i see a center diff, so the rpm difference of the different tire sizes is compensated. sure he had should used an reduction on the rear diff, to reduce the differences and the load on the center diff bevel gears.

No sir, you see an adder connecting two RC motors. Yes, it uses the differential piece, but it doesn't act as a central differential.

Edited July 28, 2013 by Sariel

[efferman]

both rc motors acting on the same 28 tooth bevel gear of the diff. the front diff output delivers the torque to the front diff, the rear to the rear diff. on an adder the buggy motors would be on the "outputs" of the diff. where do you see an adder?

[Sariel]

Sorry, you're right. I've been looking at this the wrong way.

[Blakbird]

I love this model. The flat bottom is cool and I have never seen anyone find a use for that 8421 windshield before.

[skriblez]

Man i would like to build this!

Are there any plans for instructions?

Bit oft but how much do the buggy motors go for on average?

'bout $30 http://www.bricklink.com/catalogPG.asp?P=5292&colorID=11

[weavil]

The center diff would compensate for the smaller wheels/tires, but with how much power it has and the fact that smaller wheels accelerate quicker, wheel slip can be expected.

[snot]

Awesome! I'm curious to see your controller setup. Any pics?

[tibivi]

This is just great, :thumbup:

[KirTech LAB]

So, the question was resolved without me :) Yes, the central differential gear is working like central differential without any wheels sliding.

Maybe i'll working under instruction after L-motors mounting!

Awesome! I'm curious to see your controller setup. Any pics?

I'll add picture later. Controller consists of two 9398-like controllers placed sideways. Thumbs controls the steering and the acceleration is controlled by index finger.

[Kwon]

Fantastic!

Sorry if this comment is a little late, but that is a great MOC! I really like the way you used the mini suspension hubs as 3l links.
