Default Servo Recommendations?

Just got my F104. I haven't started building yet, and I need a servo. How much torque and speed does an F1 car require?

I'm using a Futaba 9551 in my TC. I think that it cost me $80. I'm hoping that I don't have to spend quite that much on a servo for my F104.

Suggestions?

Setup is about getting a good compromise so you can drive the car to do the best laps possible. So you are partly right in that a stiff car does have less traction in general but if it is too soft, you can also wash off corner speed and be difficult to drive.
Thank you a lot!

My next "hop-up" will be the rubber tires of the f60.

futaba s3001 will be fine.
but you can use small servo so it can be mounted at an angle, it will reduce bump steer.
look at page 24 (horizontal) and 39 (angled).

Thanks Krat. That helps a lot. My biggest concern was knowing where to begin with regard to servo speed and torque specifications.

I would like to take the angle mounted servo approach. When you say small servo, what size (or model) should I look at? There are some really small servos available.

Servos suitable for 1:12 pan cars works fine with the F1 cars - I'm using a JR-Racing Z3550.

Here's my 104 Pro that I built for the big F1 day at Tamiya last weekend, but couldn't make it due to illness in the family..

And where I notched the chassis so I could use my Orion 3400 LiPo

Super Autobacs...

excuse the crappy photo, I was in a hurry this morning... but I'll get better photos later (you would think that being a professional photographer that I would have taken a better photo... but that will come later)

I have an F103 which I almost never ran, although I bought some spares and extra wheels for it.
I'm thinking about getting serious with racing with the F-cars and about selling the F103 and replacing it for a new F104 (pro).
I think I read somewhere that the F104-wheels differ in dimensions (slimmer but more important; also another diameter)

Is it possible to use some parts/spares from the F103 on the F104 and even more particular will the F103-wheels fit the F104?

thx for all info/advice

The part about the diff was very intressting. I could now fix my problems on low grip tracks.

@low_e: rear tires should fit F104. Anywhere in this thread is a solution for your front tires.
