rc buggy for Buwizz fast car competition

[Jantayg]

Hello Guys,

Today I would like to present my first moc here, which was built for the Buwizz fast car competition. I have been back to Lego for about 2 years now. I have built a few Mocs, and mods, but I have not found them good enough to show to others. :)

I hope you like this little buggy, let me give you some more information about the build.

I was half way with a build when I heard about the competition, so I decided to change that according to the rules. I usually build with more motors, so the challenge for me was to make the model efficient. I started with a 4wd version, with differential on both axles. The main feature was the independent suspension with small pneumatic pistons as shock absorbers. I started to test this solution on Agrofs buggy modded by Kbalage. It worked well, so I decided to use this solution in this build to help the stability of the car after the jump. As you see, I had to give up the 4wd setup, as the single rc buggy motor even with Buwizz 2.0 was just not enough to do the job. I have some pictures of the old version, and I have a plan to put 2 motors in it, will post that, once its built. So I decided to reduce the friction by eliminating all the gearing, so the rear wheels are propelled from fast output.

I hope you will like it Guys, let me know what you think. :)

Great buggy! Love the styling.

Cool and simple - I like it!

[MajklSpajkl]

Funtastic! I like the proportions and the overall stance. How bad did the motor got hit?

Did the pneumatic dampers require softer schocks? I really have to try this kind of suspension...

Good luck in the competition, i only took a quick look over the competitors, but you sir are going strong IMHO!

The aggressive stance and curves look good, and a bit futuristic.  The rollcage and engine details in the rear are cool, but some lights might be nice to have.

Good luck in the contest!

Thanks Guys,

I know I could have put lights on it, and I was thinking about interior too, but has not done it at the and, as was focusing on the performance. I made lots of test jumps, and videos, but was not happy with the result.

Regarding the suspension, I found it that its better with a bit stronger spring, as more force is needed to pull the piston out, I hope you understand what I mean. 

The motor is ok, a few scratches on the bottom. I was expected a bit of damage on the parts, as if you go outside, increase the speed, there is going to be crashes.....

Very nice! It performs very well, I really like the black color scheme too...

Good luck, you've got my (first) vote

[miata92]

Really nice and surely lot of fun drivin around with it.

curious about how will you put two rc motor in that scale ...

any instructions or part list someday maybe ?

 

congratulate again ...for me the most valuable moc of the buwizz contest

[Jantayg]

Thanks for all the votes:)

I have about the 8th iteration, I am trying to find the ideal number of motors. I had 4 in it, obviously that effected the look a bit, but it was a good experience. I gave it up with 4 motors, as it gives a lot of challenge not just squeezing them in, but also make the suspension strong enough to handle the torque. I have 3 motors in now, with 4wd, and kind of happy with the setup. It does not look good yet, but I am happy with the performance. 

I have not got a lot of time, and I have more projects, so it will take a bit of time. My plan was to make a video of the "final" version, but was not sure about instructions. I do not want to promise anything:)

are you using 68.7mm tires ?? i cant tell... great model!!! i like it

I like how balanced it is while doing jumps. Did any of gears or (worse) motors suffered from driving on sand?

[HorcikDesigns]

Your buggy was my favourite in the competition. I really like it's simplicity. Pneumatic dampers are IMHO best feature of this MOC.

yes, this was the best compromise to reduce weight, I really like these tyres

Well, I had some issues with the sand, but not with this model. The area where I usually play with my models is in intertidal zone, and I time it always to low tide, so the sand is damp. This way it gives a very nice surface for drifting, but it is not like dry sand. Once I tried a modification of this model on dry sand, and sand was stuck into the wheel hub: https://www.bricklink.com/v2/catalog/catalogitem.page?P=x873c01&name=Technic, Steering Arm with 4 Ball Joints, Complete Assembly with Black Wheel Hub&category=[Technic, Steering]#T=S&C=11&O={"color":11,"iconly":0}

Attika visited me in the past, and hi had some issues with sand getting into his buggy motor. The sand went between the gears, and you could feel it at certain point while rotating it manually, but eventually it came out, so no problem now. 

I know that playing outside, specially on sand is a risk, but believe me, it is a great fun drifting on the sandy part of the beach:)

The pneumatic dampers is not my idea at all, I have seen it to be used like this on several MOCs. As I understood the competition, this should have been the main feature of the MOCs, so my focus was on this. I started testing on other peoples MOCs first, and at the end I came up with this. 

The rest of the model just had to be as simple as possible to reduce weight to allow 1 motor and 1 buwizz to propel it.

Hi

I understand for the lack of time anyway would you mind if l ask if you have more pictures of your front train especially ..It's so stable with jumps ... and on rocks

Instructions?

Huh???

How about this: "Dear @Jantayg, do you happen to have made instructions for this very nice buggy? And if so, did you make them available to the public? Or maybe you are selling them?"

Also, you may want to voice, why, after some time, you bring this topic up again. I can see that: Beautiful model - and the wish for instructions.

I can imagine that then you may even get a reply. Maybe not, who knows. But there should be a little more appreciation before directly asking for the idea, and the realization - rather boldly after almost two years passed.

Oh well. Times change, I guess.

Cross my fingers that you'll get the instructions!

Best
Thorsten
