setup info
You are measuring rear droop at the rear of the pod? There is no mention of droop on the Exotek build sheet? When a friend first built his he had set his shock up too long, when he accelerated the chassis would raise up quite a bit! It did seem to transfer a lot of weight and didn't appear to adversly effect handling though?
What fluid/grease are you using for dampning on the front kingpins?
Thanks!

Thanks!
Out of the box, I was having quite a bit of push on high grip carpet. Trying things like going higher on the front camber mount would cause traction roll.
I don't have an F1R specific setup sheet, but here are the settings I finally settled on which feel like a good balance to me. I'm not the fastest guy around, but constantly improving! Maybe someone else can chime in too with suggestions:
Besides basics like springs, camber, etc, I find droop to be one of the most critical settings for this car. Playing with these values will definitely help get your F1R to where you want it.
Happy driving!
I don't have an F1R specific setup sheet, but here are the settings I finally settled on which feel like a good balance to me. I'm not the fastest guy around, but constantly improving! Maybe someone else can chime in too with suggestions:
- Front camber plate: 1.5
- Front Arm Droop (take out the spacers on the bottom of the kingpin): 1mm-1.5mm (increase for more rear traction)
- Rear Pod Droop: 2mm (increase for more steering, but I don't suggest going beyond 3mm.
- Side springs: AE black (preferred). Go stiffer in slight increments if you run into a lot of traction roll. Too stiff will cause you to scrub speed in fast sweeping turns. Make sure side springs are straight.
- Front springs: Tamiya Medium
- Main Spring: Tamiya Yellow
- Tires: Shimizu 571/572 with full sauce (let tire sauce soak for 10-15 min)
- Rear Shaft: Carbon
- Rear diff: tight and VERY smooth
- Main shock oil weight: AE 35
- Side damper weight: AE 25-35 (depends on if layout is tight and twisty or long and sweeping. Heavier weight better for long sweeping turns).
Besides basics like springs, camber, etc, I find droop to be one of the most critical settings for this car. Playing with these values will definitely help get your F1R to where you want it.
Happy driving!

Got a package in the mail today! Minus aluminum motor mounts, I've got everything needed for the f1r build! Any tips? Recommendations? I've got the sticker set for a lotus, f60 body, the CF front wing brace, blue aluminum front camber plate, exotek chassis, and a f104 pro sitting on my shelf for the rest of the donor parts. Minus the blue aluminum motor mounts, what else? build tips?

Anyone use the stock f104 rear diffuser for the f1r? How did you get it to work?
#502
Also, any pics of how the rear of the body is trimmed for clearance to the tweak plates/links?

Pics?

Got it all figured out..
Took the f1r out for it's maiden voyage. Gearing is stock for the f104 pro, haven't touched that. Side dampening shock is 30wt oil, as is the main trf shock, with a factory white spring. I replaced the side springs with AE golds as the stock blacks are too soft. front is 2.0 deg. camber block (though I might switch to 1.5 for more even tire wear) servo is in the standard upright position (should I lay it down?) tires are the tamiya 54198/199 combo (spec tire for the first event we have) and dual rate on the radio turned down to 42 percent. I turned it up to 63 percent, and it's better, but on a long or quicker sweeper, the car just pushes like a dump truck. it turns just fine in a slow, tight corner. track is high grip ozite carpet. I dont want to turn the dual rate back up as I fear it will traction roll eventually. Ideas?
