It's ashame ROAR won't update there rules for several classes. They have turned into just a Nationals races and that's about it. The good old days as they say were better!

Karl - your car looked pretty good. We just need a few more on track to tell how fast it really is. Check the prior week results for any lap time comparison

Does anyone recognize this body? Look at the front, I can't seem to find which brand has the detail like that. Not Tamiya, or Bitty.

I'd like to make a 'scale' F1 like posted earlier. It looks like this EVO ER-20 body has enough length to fit an extended chassis (notice how the body goes all the way under the rear wing). I have quite a few spare tamiya parts to make an extended chassis without too much difficulty. I'd also like to modify the rear to get the axle as low as possible to accentuate the 'rake' of the real car. Making a good body will be important, because, I'm not lengthening it and adding rake for performance; it is for scale appearance. So a realistic body will be the difficult part for me.
The composite picture shows the 2009 Tamiya body over the 2021 real Ferrari car.

Question to the F1 gods out there - toe in / toe out?

I've been running 1 degree per side toe out based on my touring car experience. Turn in is good, but it still feels like it could use more on power steering. From the 1/12 scale Wiki, it sounds like zero toe / toe in in may be more common?

Roche Evo 2 / Asphalt parking lot / G Force tires

Thanks

1/12 scale Wiki
Toe-In:
The front toe is one of the more easily adjusted aspects of the car and can have a significant effect on the attitude of the car due to it being a quick way to moderately adjust Ackerman without making significant other changes. With nothing else being adjusted, going from zero toe to toe-in will give a car a harder turn-in and will tend to scrub speed with the front end as opposed to using drag brake. This can be necessary when racing in Super Stock or higher power classes and will allow you to drive more aggressively, and can help the car track straighter under power. Toe-out will tend to make the car coast more through corners due to reducing the steering angle of the outer front tire. If a car has too much off-power steering but is otherwise stable, adding toe-out can calm the car but may the car to wander on the straights especially if the front end setup is very soft.

Sounds like you could go to 0*.

I have varied between 3 deg out (aggressive) to 0.5 out (mild) . Super effective to get the turn in you are looking for and easy to adjust.

Thanks again for the responses. I decided to go to Petit RC and review setup sheets for modern F1 cars A to Z. It appears for asphalt, the majority of sheets list toe out, and quite a few are 2 to 3 degrees toe out. Fortunately the local track will have another practice day this Saturday and I plan to try a full range of toe settings - both toe in and toe out.
