i am thinking of going either super soft or medium on the front...
i am also thinking of going back to the standard pivot post...

so which combo would give me more steering????
and do ride tires fit on tamiya wheels???

oh and has anyone tried the tamiya tires on their car
thanks in advance
I got my F104proX1 to work well on the Ride Medium compound today , i have gold front springs , red centre spring , Corally red(soft) damper syrup in the damper , std Tbar , 2mm under the front of the centre shock and if you have quite a lot of toe out you get some good steering , i was smeering with G5000 additive for 20mins and warming at 70 degrees

the car was solid as a rock

Hey All,

Bit embarrasing, but I cannot recall the TAMIYA rubber tire options that are available....

Is this the lot?

54199 RC F104 Rubber Tires - Rear/Soft
51400 Tamiya Rubber Rear Tire F104 Kit

54198 RC F104 Rubber Tires - Front/Hard
51399 Tamiya Rubber Front Tire F104 Kit


I thought there was a front soft option as well....???

that would be fine if I wasnt going for TCS legal. Perhaps x1 parts would be better.

But if TCS isnt a factor up here in the NW , then the EXO and other aftermarket parts would do....

thanks guys......my car on the ride rubber works quite well.....as j-pap has stated...i am going to try the car changing the following

take out the heavyweight pivot post
soften up the front end and add some toe out
and maybe move the battery slightly forward...

and if all goes well.....might get super soft fronts as i already have great rear traction...

also on the wheel/tire situation looks like you have to do the following (we can use additive but not warmers)

match ride wheels and tires
match tamiya wheels and tires
pit shimizu tires on tamiya foam wheels only or modify tamiya rubber wheel outside edge

is all the above correct???

Hi all, few pages back I asked about servos, still no reply or info found.

So Ill try again:

Advantages of using low profile servo like savx SC-1251MG , or is it better to get something like futaba 9602 mini servo?

Finishing my X1 build and need a good servo .




Thanks to Brad at F1 paintlab for fast shipping,great service and exellent decals!

Low-Pro servos with the servo saver on top seem to be the popular option these days

Hello, Would like to know how to set-up front axle with F104 front arms and RSector expansion front parts to have 200 mm width using F103 foam tires at the front.

Some photos?

Regards.

I use Futaba S9551 with Exotek holder viz. picture. It reduces bump steer and Ackermann can be simply changed.

Use the longer axle and the whole knuckle must be lowered as the F103 tires have smaller diameter...

Thanks for the information dfx, anyway i would like to see a real photo of one F104 with this extension kit mounted at the front using F103 tires and F104 front arms, just to know the right height for the steering blocks.

My idea is to use these longer axles to obtain 190 mm at the front on a FS104WW Sybrand chassis (originally F104X1) and transform the car in a FS104WW/F104W hybrid with F103 foam tires.

If I use the ordinary F103 front parts I lose the front roll damper Sybrand FS104WW ability

I think 200 mm/ bigger 4,5 cm rear foam tires makes the car more stable and fast at our nitro asphalt tracks.

If your question is what advantage a low profile servo has over a mini servo, well if the servos have the same speed and torque then there's no difference.

If your question is the difference between vertical and horizontal mounted servos, the biggest difference is what it does to the Ackerman. The vertical servo keeps the servo saver in line with the steering arms, so limiting the amount of ackerman angle when cornering. The horizontal mounted servo like dfxs above means as it steers it moves the steering links back and increases the ackerman angle between the wheels.

The increased ackerman of a horizontal servo means you get smoother, consistent steering with less turn in. A vertical servo reduces the ackerman which gives you more responsive and aggressive steering, especially going into a corner, but it can wash out when accelerating out of the corner.
