Hello, jumping over to electric! Anyone have a good starting setup for outdoor asphalt track? Pit Tires or Tamiya Tcs tires. Thanks!

Rear:

Kit side spring just touching
20K CRC damper grease
12 lb center spring
25 wt oil in the center damper.
1 mm sag, 2mm droop
5mm ride height
Shimizu 579s

Front:

Stock F104 Arms
1.5mm camber
Silver springs
1 mm. droop
574 fronts
Horizontal servo about 2mm back from stop.
turnbuckles in last hole on the steering upright.
turnbuckles parallel to the ground.

Symptom:

Losing steering and going mildly tight, pushing to understeer, halfway through the corner. Rear end is tracking very nice. It feels like the inside front tire is slipping when the weight transfer goes up. Either that or I have too much body roll and am running out of front droop.

Any ideas? I'm thinking stiffer front springs and heavier damping lube for the side to side damper to start.
You don't like the 'Soft' 71 fronts? 74's push for me.... Around here 74's are for when grip is very low and you want to induce a little understeer for the sake of stability.

On colder carpet guys use 75/ 71 combo. On high grip asphalt/ hot carpet 72/71 combo.

Exotek driver Aaron Lane (Wheelz) TQ'd last weeks UF1 race with 71/72.

Build it to the instruction sheet to start and see the set up notes on page 2

Default I have weakened

In Australia we run both wide and narrow cars together as the numbers are not big enough to separate the 2 chassis's.
After struggling with the narrow F104 gear to match the wide chassis's I have folded and gone back with the wide setup.
The difference was Q11 to Q1 in one heat and clocking the fastest lap in the heat and 2 finals on the day just by bolting on an F103 front end, without touching the rear end.
I have tried everything I can think of to make the narrow front end to work, but just cant match the wide cars consistently. The front end turns in well, but suffers from mid corner under steer and slow mid corner speed.
All fun when you are back on equal terms with the new batch of cars being released in the market.

Here's some video of my F1R mixing it with F113's
This was a benefit race meeting for one of the fellow racers who has been struck down with various illnesses over the last few years, he starts from pole.

I hope you enjoy my GF's recording on her Samsung Tab

Welcome to the dark side

I have been running mine in wide mode from day 1,
I still think a wide exotek is better then an F113

did you still use F104 tyres or were you using 103 ?

Beth.

Which Exotek chassis do you prefer? I like the looks of the F1 Ultra, but then there is the other....

I think my Ackerman is messed up, the servo was too far back and Ackerman was too high. Not enough front droop either. The car was only a couple tenths slow. I've got a setup ready to test and the second car is almost done. The soft/soft combo worked well, but if temps go up, I'm sure the traction will fade.

My F1R is in the mail, should complement my 104pro nicely. I'm going to piece this one together while keeping the 104 for racing. What mods is everyone running and doing? I already got the lay down servo kit and adjustable front arms. I'm be running the aluminum front Camber mount and motor mount. I also ordered all the spring rates for the sides that were in Stock.

Steel or carbon rear shaft? What about the side damper?

Hi Beth,
I ran this in F103 set up at C'hill when I first bought it as the F1R replaced my F103 Tamiya RM. I had to modify the standard steering knuckles to get the ride height in the front or it sat at 2.5 mm.
After my winter break from racing I changed to F104 over the last 5 months for something to try. The F1R has been quick in either form, but in F103 set up it is always faster at most tracks, except at the recent Summer Nats.
I changed to the F103 front end and tyres with F104 rears after the second heat at the BRB meeting and guessed the set up.
Fortunately I had recent acquired some TRG steering knuckles which makes life easy to get the right ride height and steering arm position. I ran these with 3.5 mm trail in the F103 front end.

CYA next Friday night
Pete

Run it stock recommended settings and see how it goes, you will be in for a pleasant surprise, keep the set up guide on hand for fine tuning.
I you drive like me (hahaha) the steel shaft is the go, broke my carbon shaft in 3 laps due to a tyre bead un-glueing.

Question for all ?
Has anyone tried using a servo out of a 12th scale car ????

180mm F1r was untouchable on the rug in dallas this weekend! Been working on my set up and could not break into the 12's, been hovering at and near 13.0 for a couple weeks now. Main improvement was getting the c.o.g. lower so I could carry more speed without traction rolling. Also making it a point of not gluing the sidewalls or making the car wider. Finally pulled off a 12.9 in the third qualifier! Now its time to seek out a 12.8...

For reference a great 17.5 sedan lap on our current layout is 12.3 and a good wgt lap is 11.9.
