Here is a cool article about downforce generated on RC F1 cars. I don't know exactly what it says but I understand the numbers they're posting. If anyone wants to translate and post what's written I'm sure everyone would appreciat it.

I'm not sure what pinion has been included in the kit box stock, but you can use that (number of teeth for pinion) against the 93T (if I remembered correctly). And with that gear ratio, do a math on your 64p Spur that you want to use to find the pinion. This is a method of subsitution, so anything fast will you have to buy bigger pinions from there.

Remember to file down the width of the 3Racing Adaptor to as wide as the width of the 1280 bearing.

Default Rubber Tires

My understanding is that the only rubber tires available are the F103 tires and wheels. I would like to mount Rubber on the F104. If I install the front arms for an F103 on the F104, would the front have a wider footprint. Any opinions on how this would effect the handling? With the push I am reading about, this may help.

Yes, by using the F103 front end it would be much wider than the F104 rear. I could be wrong but, I'm pretty sure this would make the car really push in the corners.

Just an FYI, regarding the article from rc-japan.de on wind tunnel testing rc F1 cars; I've got part of it translated and posted at the link below.

Vyger is correct--wider front track = more push. This alters ackerman angles.

The narrow your front end is and the wider your rear is, the less push you will get.

Ok, then can someone tell me what the difference is with the F104 that the F103 wheels or tires will not work? Maybe I can look for a modification that will allow them to be mounted on the F104.

Front = The F104 uses a larger kingpin than the F103, hence the larger diameter wheel. Since the F103 wheels are smaller they will rub when mounted on the F104.

Rear = The F104 uses a one piece wheel because you donít need to mount the thrust assembly in the wheel anymore. It also uses a shorter wheel hub for the same reason. As far as mounting the F103 wheel on the F104 Iím not sure you canít. The offset maybe different but Iím not exactly sure.

I hope this helps.

I'm pretty sure if you put the 103 rears on the 104, the car would be much wider in back.

If you put the old suspension up front, with 103 tires on all corners, it's a Tech car

Do you follow the instructions regarding the orientation of the cone washers in the thrust bearing? Has anyone (if necessary) reversed them?
