Hi all,

I am new with this car (not in F1) and I have some questions that you migth be able to answer:

- in which conditions the speepassion carbon/reinforced parts are recommended? Are they only for carpet? Or do they add some benefits also on asphalt?
- which pinion would you recommend for a 21.5 and 17.5 motor? I have never used 64p spur gears on asphalt and I am wondering if I should use them or directly fit a 48p speedpassion spur gears that also use 16 balls (probably more durable than the 64P)
- I have seen people replacing the servo arm by a servo saver and connecting the steering links directly to the servo saver (instead if using steering rack). To do this modification, I have seen that the servo should go horizontally (with the servo saver on top of the servo). Do I need to have in mind something else to do this mod? Does this steering layout provide any benefits (maybe more direct steering)?

Thank you in advance

The SP carbon uprights are good for any surface, the rev b ones are thicker where the stock ones break

the carbon upper and lower arms are for carpet, you give up too much grip on asphalt with them

you usually want around 2.7-3.0 FDR I only run 21.5 and usually run around 93/33 spur/pinion
I prefer 64p , finer FDR tuning. I only run the xenon 64p spurs, they give you 16 balls for a great tunable diff

the laydown servo is easier to fit under bodies and less slop in the steering, it feels more consistent to me. You have to cut the carbon arm mount plate to do this the best way

With the electronics and battery installed it sits a little more level with the chassis so maybe when driving it around the track it might level out.

I double checked the shocks and they are tightened all the way down. And you're right about the threads being very soft. I almost ruined the threads when I noticed I was tightening the cap at a slight angle.

Yes I put the spacers under the piston. I made sure of that when I noticed it was hanging lower than the chassis. But it's good to know that its supposed to be like this because I thought I had somehow assembled it wrong.

Thank you very much, your answers have helped a lot!

Just one more question. When using the laydown... Does the height matter? My point is that depending on the height of the servo the Ackerman and/or bump steering might vary a lot. Do I need to check something to make sure I have the right Ackerman and bump steering?

Thank you!

yes the height matters, that's why you cut the arm plate also very important is to move the servo forward and back based on the caster you run.

If you look at all the different setups on petitrc, posted above you will see how they measure the distance

Ok thank you very much!

And which is a good base setup for asphalt? And for carpet? I am driving both in carpet and asphalt

Hara's setup for asphalt?

Thanks a lot for the help

Thank you!

And for carpet (Now during winter season, I drive indoors on carpet)? The ETS setup perhaps?

I have seen in Hara's setup that RIDE front spring are needed. But I can't not find them. Could someone let me know where to buy them? Or at least the reference number?

Thanks again

Apologize for the silly question but it is the first time I heard about the ride springs.

Thank you!
