[MOC] Porsche 918 Spyder

[Jonfensu]

HI

This is my dream Porsche for the Lego Rebrick Contest a LUG contest 

It was built in one month 

Features 

- 1:10 Scale

- Working steering wheel and HOG steering 

- Independent suspension

- RWD and 3+R gearbox (the same of Lipko's Simple Supercar,  though with a different structure)

- Openable doors and trunk

- Adjustable spoiler with a knob 

I just wanted to share it with you to know your opinions and what could be improved,  because it's not the final version.- let's call it Ver. 1.0 - Initially I wanted to create a sequential gearbox with paddle shifters using shock absorbers. I built it, but it didn't work well. Also, I wanted to build a similar suspension setup as the Carrera GT, but again I failed.

So I ran out of time and patience and build a simple mechanism.  Anyway,  my initial plans are still up and if is possible include RND and AWD though right now (to me) seems very hard to do in such scale.

About bodywork.... There are some sections (like the headlights) including color scheme that I could improve but I have to buy the parts first (my inventory is really small compared with many of you hehe).

Here are more pics

Nice car. At first I thought that it was some type of Police Interceptor.

Great job so far, thanks for sharing !

This is a Porsche. So the wheels from 42056 will be perfect

Thanks Meatman...A police interceptor..Hmmm, I did not think about that possibillity but sounds great, just need some blue and red lights

Thanks Bruno, I really aprecciate your opinion (Even I was waiting your post and experience ). I have read your first comment and I will take in consideration the use of soft axles, though, currently I do not have 16L (its quiet expensive) but I will try to get some in the future. About shifter mechanism, your prototype looks great, especially that it was working smooth with the regular 3L connector of the newest driving rings. Are you building a manual Supercar? 

About my shifter concept, it was different. It was using 2 soft shock absorbers behind the driver´s seat for each paddle shifter. I´d say that the paddles are finished, the complex part comes with the shifter itself.. Lets see what I can do with my limit experience, because I want to create my own version, but I will try to take the time to make it

Yeah, those wheels are beutiful, except for the abscence of axle connection. Sadly they are only compatible with 1:8 scale

I´m glad the message has reached you  . I guess I was wrong with 16L - shouldn´t it rather be 14L (don´t know how rare or expensive those are in your country)?... Anyway, you can get creative and try other options, probably you have a flex axle in some other colour available to spike some 2L black tubes on and/or use pneumatic tubes. Many people on here prefer puristic style, but depends more on what you like.

I´m definitely building a manual supercar among others, but don´t expect too much and too soon. There is probably nothing unique to come because everything has been explored in this field as some others say . Not sure if I won´t change everything in my gearbox again and go on with smooth driving rings. The playing and understanding is more important to me than presenting spectacular results. All I want is a functional and comfortably playable (!) car where all the handles are where they have to be.

Yep, you're right. It should be the 14L one, but oh God,  those are expensive! I have to buy the parts in bricklink,  so you have to include €5 of shipping. Indeed, that the best way is using pneumatic hoses. Just for the "economic shake". The possibility of buying parts here, directly to an AFOL,  is null (the only exception was a 8461 that a LUG member bought here for $20, but that will not happen again) 

Is really nice to read that you are building a manual supercar,  I am looking forward to it,  definitely! . I don't think that everything were explored in the manual supercars.  Well,  the only exception are the cars built in 1:8 scale, but the 1:10 supercars still have "room" (though not so much, literally ) for improvements and features, for example (correct me if I'm wrong) I have not seen one with working paddle shiftes and RND selector. So the challenge is up.

You are right and I didn´t say that seriously, because real cars are advancing technically as well and get new features from time to time  !

Wow, this is a cool car. So many clean lines and well thought out. Nice work

Thank you. I am glad that you can see the headaches that gave me some sections of the car. It was not the case in the LUG,  so I got a 3rd place in the contest. Mixed feelings about the result. BUT in the other hand I won a pneumatic V2 system , and I don't have those pieces

Anyway. Going on topic,  I've been working on the paddle shifter system,  using my initial concept (shock absorbers under the driver seat). The main goal was making the paddles closer to the real life, with short travel, closer to the steering wheel and without visible rubber bands on the dashboard. All in a module that fits in a 1:10 car. Though it is still using one rubber band for the 90° limiter created by @Didumos69 

Here is a teaser of the concept

If You turn headlight brick by 45' , and put there four transparent knobs, headlights will look like on real Porsche. Otherway, good shapes.

Could we see link to other contestants?

Nice to see how this is progressing. I'm amazed how small the movement is that is needed to make shifts. It seems you do need quite some power to shift though, but still okay I think. The paddle unit reminds me of this one (he uses a lot more silicon than you do of course ):

But you're video makes me even more curious about how this magic shifting box behind the driver seat works. You seem to have hidden its contents carefully. Could you tell or show us a little more about what's inside that box? And about the limiter at the back: I suppose the #2 connector will be braced better, because this way it will eventually slide off the shift axle.

Btw, I just read this complete thread and I really like the goals you have set and the fact that it will be a pure manual model. I will be following this more closely.

I had the same question in mind. Very nice shifters ! And I´d like to learn something about the contest too .

@Didumos69

About the force to do a shift, I think I should compare it with other paddle shifters,  but I guess there are three factors: the structure around the steering wheel must be stronger and well attached to the chassis;the paddles and the links in the steering column are shorter compared to the one that you show us in the video,  so the lever effect will not be greater  and I was using one hand to do a shift and hold the module at the same time 

I will try to resolve one minor issue, after that I  will give you the ldd file

@Jurss Thank you for the suggestion,  I will take it into consideration 

@brunojj1 I will tell and show you in a PM the contest , just for the on topic sake 

 

[Jonfensu]

Shame one me. I forgot to say 'Thank you' to all for the positive comments and interest on the shifter 

I've tuned the shifter,  and now it works flawlessly. Now it feels softer and even require less travel. Before, the shock absorber was compressed 3/4 stud, and now compress 1/2 stud. Also the returning of the mechanism is softer. On the con side, when I pull de shifter, it will not make a complete 90° rotation, (as you can see in the picture) but it's not a big difference and it will complete the rotation once I release the paddle (With a huge help of the limiter )

How it works'. Each paddle is independent and has a knob for each one. Basically it uses the principle of a stopper, (independent) but not fixed. So there is a synchronized movement between the stopper and the knob. Once I pull the paddle,  both pieces get in touch,  making the shift. Once I release the paddle, both pieces go away from each one freely without turning the output knob. Also the "walls" on sides are not just to hide the content 

I could share with you a picture,  but still I have to figure out if it works with the gearbox (that I've to build It). I will share it in the future.

Sorry

You're welcome! About the shifter not completing a 90° rotation. My experience with shifters is that it's best to have a shifter that does complete a 90° rotation. I would only use the limiter to avoid backlash or for cases where the driver doesn't finish a complete paddle shift. The problem is that when the limiter needs to help finishing the rotation, it probably needs more than one silicon band, which will also make the first half of the shift less smooth. Just my experience, could very well that you will get this to work properly.

It's beautiful (though I agree that the color scheme should be improved/finalised). The building style reminds me of Crowkillers' latest cars, and I like this style the most.

Of course - good solutions awake the interest. And I´m waiting for the LDD file and / or new video with the "better" version 

[Aleh]

Thanks for sharing your model! Why you made a decision to make it without any front lights?(
