- cologne - 05-26-2007
According to the rules updated all cars to a total weight of 610 kg
Quote:ARTICLE 4: WEIGHThttp://www.formula1.com/insight/rulesandregs/21/5276.html
4.1 Minimum weight:
The weight of the car must not be less than 605 kg at all times during the Event.
The version of the new mass is Version 2.1 and higher
F1-Car for fast tracks - cologne - 05-26-2007
Here my actual definiton for fast tracks as Monza and Le Mans. Nearly 380 km/h. Drive and brake carefully at lower speed. Oversteer characteristic.

Yes, the tire model is very complex. I haven't been around much, I have been very, disgustingly, busy at work for at least the last 3 months. Maybe it's been longer, I don't remember. Anyhow, yes, the tire model is imperfect. I have not tried these new cars out, but I know we do not have enough sidewall flex, and the last F1 car I tried, the model had too much suspension travel. It's something to think about. Hopefully soon I will be able to work some on the tires some more.
best laptime in Monaco - foyol - 05-26-2007
well, my best time with your setup is 1:23:736, but without the chicane after the tunnel (i go straight ahead). i think that respecting the chicane i can go around 1:30 (I'm surely not Senna, anyway).
Since the car don't report damages in VDrift, i can't tell if my lap is perfectly clean, so take my best time merely as an indication of what i would like to do if i could
going to look at the map, thanks again

Quote:the last F1 car I tried, the model had too much suspension travel.
I corrected this. Please try out one of my modifications! They are much better than the release F1 definition.
New personal record on Nuerburgring: 5:52 with the mid-fast 2.1.0
New personal record in Monaco: 1:26 with the slow 2.1.0
On Mosport: 1:02 with the fast 2.1.0

Pole Position

(Williams-BMW FW24)
1:16.676 (158,224 km/h)
Fastest Round in Race
Rubens Barrichello
(Ferrari F2002)
1:18.023 (155,493 km/h)
I guess that i loose a little time using a gamepad. In some curves i use a higher gear, its easier to control. I (try to) drive through the cicane, braking in 6th gear to 2nd.
I analysed weight and weight-distribution. Oh, the engine is placed between the knees of the driver!!!
I changed the distribution to nearly 43% / 57% and had massive problems with a very "dynamic" rear. Lowering the suspension values the car drives nearly as before and he has more "mecanical grip".
The suspension seems too hard in my actual 2.1.0 release!!
Next days comes a new slow version: Please post your impressions!
scaled down F1 ! - cologne - 12-23-2007
After some month doing other things in my free time - two free falls with bycicle and airfoil, programming my CMS-Framework and researches in local history - and buying a book about blender i made a new attempt to scale the F1.
This time i haven´t any problem (before i didn´t "apply" transformations...). Also the real F1 wheels are exported.
There are two new pictures in my gallery for comparison!
The smaller F1 behaves much more nervous (masses are more concentrated) and needs some fine tuning.
I will publish the whole package in some days...
