[TC25] 42143 Ferrari Daytona SP3

[msk6003]

At first, I planned to make 70% scale of 8485 Control center II with 51515 robot inventor hub.

But Jim said no electronic.

I will not scrap those chopper yet but I don't know I will did it again someday.

Anyway, while thinking idea of set, I find this comment.

@gyenesvi said : Imagine we have a shrinking contest without any constraints, and let's think about two possible entries. One contestant picks a 1:8 supercar, makes it 1:10 or 1:12 and keeps some of the few functions, maybe drops the gearbox; the result is still big and may look cool, but technically shallow. Another contestant takes a medium construction set maybe, makes it smaller but keeps all the functions with a lot of technical tricks and cool building techniques. Suppose that both entries would adhere to the rules, so none of them would be disqualified by the jury's pre-filtering, and then voting is passed to the crowd. Which one keeps the spirit of the contest better? Probably the second. Which one will get more votes? Probably the first.

So we have limit of electronic but no set limit? Than I will did it. Don't blame me. I select this because all my other option use electronic.

First, I got the .io file of the original model and reduced it by 0.63x using Part Designer. Due to the large number of parts in the model, all the interior except for the exterior was scraped due to serious lag, and independent suspension cannot be inserted here if it is smaller.

Then, after setting the wheel positions based on the scale model, assembly started from the rear. This is the narrowest possible independent suspension, and due to space issues, the differential gear had to be removed and only a 4-speed gearbox fitted, rather than the original 16-speed forward and reverse gearbox.

 

Planed function

4 speed gearbox with paddle shift and V12 engine

Independent suspension on all wheels

Front wheel steering using steering wheel

Opining door, hood, engine cover

I have to warn you about something in that comment of mine; I noted that for the case of crowd voting! But this contest will have jury voting, so I don't think it will hold for this case, because the jury will not vote just based on the looks and the size, hopefully.

Other than that, I think the choice is not bad, it's a good challenge. I also think that reducing the gearbox from 8 speeds to 4 speeds is okay. I'd try to keep the differentials though, and that seems doable with the new double ended CV joints of the Ford GT.

About electronics, I actually like the option of taking a set that originally uses electronics and making it manual, and Jim said that such a build could actually make a good entry. Can't that be done with one of your original ideas?

8485 set's main function is record&play using control center. It is not possible without electronic.

I don't heard this TC has jury. Is it real?

Before built those axle I considering ford's 5L joint too. but for adding differential I need 4L joint.

The TC25 contest discussion thread says so in the voting rules.

Who reads the rules :)

Good choise. Reducing 2x gears in shrinking contest is OK, I think.

Using small turntables as wheel hubs, reduces width by 1 stud, which could be enough.

Chassis done.

Put paddle shift in this size vehicle was extreme challenge but I did it.

Compared to the original model, the engine is slightly forward, but acceptable.

Good progress and a nice set to shrink!
