For foam that might be the case although I've run 1/12th scale on and off for almost 30 and never ran toe out. Toe out on rubber tire cars makes them twitchy.

Yeah it does sound illogical at first. All setup guides say toe in would make the car more stable on the straights but difficult on turn in and toe out is exactly the opposite. Doesnt hurt to try I guess. Its a simple setup change.

Also add some - expo in your radio to desensitize the steering
I do have some droop both front and rear. I didnt really measure it tho but around 1-2mm looks about right with the stock springs

Ill try a reduced camber and caster and see how that works out. Thing is I have a similar setup on my other F1 and that car handled like its on rails. The WRC with a similar setup is all over the place down the straight.

Ill try some negative expo on the steering as well.

Thanks for the tips guys

Also what is your shock angle like?
The more angled the shock is the more sensitive the steering will be. The shock height and angle are very much like the rear roll center for the chassis

I took out one shim on the rear to lay the shock down a bit more from stock since it I feel like it was too angled. Ill start taking out more to lay the shock more and see if that helps.

Don't know about foam tires and toe in/out but for my f-one 2014 and my f-one 2016 on rubber tires I definitely need a fair bit of toe out to make it less twitchy and stable at speed.
My suggestion is to try it yourself. It's an easy setup changeable makes a huge difference.

Doesnt hurt to try, just a few turns on the turnbuckle anyways.

Did you have the problem where the F1 fishtail uncontrollably down the straight when you give it a little steering input?

And more. The car would fishtail a couple of times then spin. Just felt like someone turned full lock at speed.

Yeah I had exactly the same problem with my WRC F1. Steering adjustment down the straight will lead to uncontrollable fishtailing and ultimately spinning into a wall.

Which ackermann angle did you use, forward or backward mounting holes?

With the 2014, I would change it depending on track. (I race on outdoor asphalt). My new 2016 I am still working on what feels right for me.

Ah alright, Im running my 2016 on asphalt too. The setup has a long way to go compared to my Exotek F1R3

Default fishtailing

i have the f-one and because of the design, the front end has a lot of flex. If you have fishtailing and stability issues, I would run max caster, hard front springs, soft rear shock and side springs, 0 or -.5 front camber, and a harder front tire to limit the front end grip. You should also make sure the rear pod is free and not binding.

That would depend on the surface and amount of bite. I would definitely run a softer setup, let the chassis roll more to create grip. Ride height would really come down to how bumpy the track is and how much suspension travel is needed

Sure you're absolutely right.
But still I need a good starting point for my first time out with an F1 on asphalt.
Track has some little bumps.
