Does anyone know if the 3racing truer adapter "for Tamiya f1" will accept f104 wheels? Any experience with the quality?

No where has the kawada arbor in stock so I'm thinking of getting this instead.

Adding more weight is the worst thing you can do. Try lowering the ride hight at the rear.

After you've exhausted all things you can do to gain side and forward bite, then add weight. Another F1 racer where I race added weight to his car and it's planted. Think about it, the car was designed with NiMH's in mind which are ~100grams heavier than lipo's. I don't think adding some weight to gain more traction will hurt.

I've added about 14g to the front before but never added weight in the rear before. What tires or foams are you running?

I just got a F104 Pro with Yeah Racing hop up parts. It was set up for carpet and it has a KO Propo steering servo. I plan on racing at the carpet track at TQ Racing in Chino. I want to run a brushless system and I want to run LIPO batteries. Can someone point me in the right direction as to what to get in regards to tires, motor and battery? I used to race RC10L2 and RC10L2.5 at SoCal Raceway, I have never raced carpet, only asphalt.

Looks like i mistyped. I have added weight to the front (14g) but never to the rear. If your running Soft front and rear try the harder compound fronts. Your getting too much mechanical grip in the front it sounds like.

First thing, I'd go to the track\website and find out what the rules are for the F1 class at TQ Racing -http://www.tqrcracing.com/track/tqcarpetseries2011.asp. Looks they run foam and rubber - you need to choose? If you go brushless, I'd pick up a decent speedo with a spec setting and also pick up a Novak Ballistic 21.5 since it has the most mechanical timing (~30degrees). As for rubber tires on carpet, I'll have to defer to someone who has run the F104 with rubber tires on carpet. As for LiPO, any decent LiPO that will fit in the F104 Pro.

The UF1 Winter Series at TQ is Rubber Tires only. It will be personal preference in what tires you like best so you'll have to go out and do some testing. Any 21.5 Brushless motor/ESC combo with a 0 timing spec mode is allowable. My brother and I bought the Tekin RS 21.5 brushless package to run from Stormer Hobbies. As far as Lipo's are concerned you can make most any of the hard pack 2 cells fit it just takes some modifications.

Go to the soft t plate. Could be to much front grip.

It depends what the car actually needs to do on the track.

Adding weight to the rear generally makes the car steer, or rotate more, actually, as the weight increases the "pendulum" effect as the car corners. It will be more stable as far as going in a straight line, with more weight on the rear tires.

More weight on the nose will make the car less twitchy, and feel more stable, but it will have more steering overall. It's like putting a case of water in the front of a shopping cart- it's hard to start turning, but the inertia keeps it going.

I have added about 40g (20g each side) to the front most part of my lipo battery, and 60g (30g each side) to the rear most part of the lipo. I am running the f104 with option tamiya tires on medium traction asphalt track with great results

Do you guys tweak this car? If so how is it done to get both tires lift off the same time? (as there is no side spring tweak screws)

On my last race day, by the third heat my car was oversteering/spinning out of corners on left turns while steering right it's pretty planted even on throttle.

I then noticed at the end of the day my front left tire is about 2mm smaller in diameter compared to the right (55/57). It was my first time racing it so i'll keep an eye on the diameters next time in between runs.

I suspect that would be why it was inconsistent in left/right turns?

Anyways I'd still like to know how to un-tweak the chassis.

Thanks

You can add shims between the rear pod and t plate depending on which side needs it.
