[MOC] Subaru WRX STI W/ Instructions

[Touc4nx]

I started the digital building

 

 

[Touc4nx]

The full bodywork is done.

However, the price is already pretty high, without the use of the black pins :

Great work so far! 
 

By the way, the Studio prices are based on averages of new pieces. It’ll be approximately half if you buy used

Thanks 
and for the price I didn't knew that but it seems logic ;)

[KD123]

Amazing Work!  Only thing I'd recommend is considering the use of flexaxles to form the shape of the fenders.

use of flexaxles

It's done on the real model, it's just not visible in the render as Stud.io doesn't allow to flex the axle great.
By the way it's been a long time since I haven't uploaded anything new because I was working on the chassis. So now I'm proud to present you the whole car :

I will now start doing the instructions for it. 

Just for fun, here is the gearbox :

Hope you like it.
And have a nice day.

[LvdH]

Fantastic job! I just might have to build this. Are there any exceptionally rare or expensive parts?

I don't think, just looking at it, however if you want to get rid of every visible blue pins it will be expensive.
And there is also a decent amount of black 3L axle.
And 16 6L thin Liftarm in light bluish grey.

You will need a 4.5cm long pneumatic tube in grey :

It's to make the Turbo :

You also need two 16L soft axle in black.

And I made the car using a BuWizz to get a pseudo-decent performance.

I think that's all, if I find any other part that might be rare or expensive I will tell you.

Added some Rare/Expensive parts

Instructions are coming along nicely.

For now I just have made the chassis and the gearbox. And it's already 341 pages long

How do you get correct ackerman geometry with this steering setup? It seems to me that this makes the outer wheel turn more than the inner wheel... Is there something I'm not seeing with KPI angle that affects the geometry, or is there another way you are getting the angles right?

The Link is mounted further inside than the joint the steerin pivots on - thats all you need 

[Touc4nx]

Here are some schematic to clarify it @Nazgarot:

The blue line represent the inner wheel and the pink represent the outer wheel.

[Nazgarot]

This would be correct if the steering rack was behind the wheels, but with it in front it should be oposite unless the KPI angle shifts the wheels more/less sharply due to height of attachment of the steering rod  changing as the wheels are turned...

Se illustration of typical ackerman geometry. May it be an anti ackerman setup for some reason? I can't say it will be a problem, but a deeper explanation of why using an anti ackerman or why I'm wrong would be nice (I always like to learn something new).  :)

Corrected spelling

[Gray Gear]

I did not realize the links were in front of the axle. Yes, this seems to be a problem.

I'm sorry but I can't help you, it works but I don't know why 
maybe as you suggested it has to do with the kingpin inclination and caster angle ?
Here is two picture if that can help.

 

[Nazgarot]

Well, thanks anyway for taking time to post the picks.

I'll have to do some research on this. Could be very helpful in future builds if I can find out why it works.

[Gray Gear]

Well, I dont get it. It seems to work, even though it shouldn't. It is bothering me, if someone can explain this please do. 

I am no expert in this field.

[Touc4nx]

Just a quick update as I'm doing the instructions :
you can download a .csv with the part list here.

 

[Touc4nx]

Step 1000 of the instruction is here.

Instruction are 90% done. Then I will have to check if they are right (and buildable)
Anyway here is a render of the different colored ones (the background isn't part of it)

 

[Touc4nx]

Ho Ho Ho, Santa is bringing you presents. (Jokes apart it's been a long time since I hadn't updated this project)

The car is finally finished and I have done and checked the instructions. It's a 1218 pages long pdf with detailed instructions. It's made out of 1224 steps for 2892 parts.

I'm considering to sell the instructions for roughly 10 to 12 € as I put a lot of time to make them. I was just wondering if I can legally sell the instructions by calling it a Subaru or if I have to ask permission to the brand for that. 
Anyway you can download a little sample of the instructions here.

And as a bonus here are some pictures and renders.

The "most wanted" pic 

Some renders of different parts

And the gearbox 

And finally; why have one car when you can have two times the same ? 

Hope you like it.

The wheels look a bit small for this scale.

It might seem that way because of the wheel arches being so narrow  in the rear. It makes the wheel look smaller in comparison to the body. Wheel arch shaping&Fitment are very important in a car, as it can easily mislead the human eye and make things look off.

I dislike the rear wheel arches, because I hate using these angle connectors for shaping wheel arches. But the rest of the car turned out really nice, especially the white one. Very recognizable

I have to totally agree with this statement, I'm not a big fan of it but for budget reason I did it like that 
I could have used the same setup as the front one (a 19L soft axle) but the rigidity of the build was compromised.

[Gray Gear]

Are the rear wheel arches narrower than the front ones?

[Touc4nx]

Yes, the front ones are 10 studs wide and the rear one only 9 studs wide.

I wasn't able to go closer for the front one and keeping the possibility to steer
