Lucky You.

I always remembered F1 from Matchbox or Majorette catalogues.
There was a poster hung by my father, perhaps of a Ferrari, I don't remember.
But when I saw The Rush…
Man, the nostalgy kick big time
I asked because I think some of your build might be better if you use paper that is a bit stiffer, like cardstock.
The area around the cockpit is a bit rough, and I think its because the paper is too thin.
But you say you are using 80g and 160g...so maybe I am wrong.

I will try to find some of the old postcards I have...I have a very large collection of postcards and photos in storage,
but it is not properly organized.

I started watching F1 around the time of Nikki Lauda and James Hunt...
and then Nigel Mansell, Nelson Piquet and Alain Prost.
I especially loved the period when James Hunt was commentating.
So the movie Rush was very nostalgic for me too!

But this earlier period of Jim Clark, Graham Hill and Jackie Stewart...is a very special time.

Jack Brabham was in that mix too.

Been away for a while
So to compensate for this, here's more pics for You All to endure.

Yes the cockpit area is more or less ruined.
As it won't represent actuall vehicle my first concept was to make a fully enclosed cockpit.
More from laziness than anything else, and in my haste to get it done I just forget to cut out the opening.
So I glued the simpliest canopy and even before the glue settled I know it was bad idea so I torn it of.

I wasn't quite clear. On this one I use 80 grade.
Models that deserve more attention (means not quickies) got the special treatment with 160 grade.

I made the wheels a bit wider, more like ones used in 69' than 68' or 67'.
As the mirrors are quite small I just made taller cones and then cut them in half.

Is this one of those where the regulation put a limit on the front wing so they went out and stuck additional aerodynamic surfaces right on top for additional downforce?

Not sure.
I think they used high wings because of advantages in cornering and not to counteract the rules.
As we are at it it's quite amazing that aerodynamic advantage went so late to F1.
I am reffering to Mr Michael May from Austria.
He put adjustable wing on his Porsche Spyder, and that's not all.
It got endplates something that wasn't that obvious then.
His Spyder in this configuration made better time that Porsches prepared by factory team.
It all went up to a point that Porsche made official claim that the wing is dangerous.
So easy, if You can't beat them You just pull all the stops and go official.
But as history shows in F1 high wings didn't fare much better.
Crashes of Mr Hill and Mr Rindt on the very same spot but separated by some laps in Spain GP at Montjuic in 1969 put end to them.
Off course we can shoot the breeze arguing whether the failures of wings in both cars were due to the lightweight design for which Mr Chapman was well known for, but...

I don't think there was anything like wind tunnel testing or computer aided design at this point.
Although there were some very smart designers at work, it was a lot more experimentation than proven science.

The wings were simple, but effective through trial and error.
And as the wings got higher and bigger, the ruling body eventually stepped in.

Same thing goes for "ground effects".
It was all kinds of out of the box thinking and experimenting.
And as they figured out what worked and what didn't, the opposing teams would try to catch up.

Unfortunately more and more drivers were at risk, and again, the rules needed to be changed for safety and to even the playing the field.

----
VonMick...even at this scale (small in my opinion!) many of the parts would benefit from cardstock ...not paper...and at least 65lb(176gsm).
I'm not sure what the 160g pproduct is (you are mentioning)but if you are using it on this model, it still looks too thin.

I'm just suggesting for future consideration...if you try this model again...maybe in colour...
give some lightweight cardstock a try.
It may feel different at first, but you'll grow to like it.

I still think this model looks neat!
And its a great subject matter.

And now stuff I don't excel in.
Painting
First try with wire - yes wire.
Bad idea.
Then with paintbrush, but nothing fancy, cheapest and well worn at that.
