Tamiya official rules allow tires trimming?
*
yup, trim tires allowed, based from tamiya official website:

Modifications to the tire's shape are allowed if they comply with the Car Measuring System outlined above. However, changing the material properties of the tire surface (including, but not limited to, applying glue or other substances to the tire surface) are prohibited.

Front and Rear Tires: Diameter: 22-35mm, Width: 8-26mm (Note that tires must be attached.)

Below my latest setup...change front roller to 8 - 9 mm

To be tested at speed houz tomowo....manage to trim the front tires but I guess can still make thinner

One thing I really don't understand about online tutorials teaching people to soak bearings into zippo liquid.

Zippo liquid does not have lubricant nor protection properties. It makes ball bearing dry and it could cause wear out bearings.

And also breaking in motors, also by soaking it into zippo liquid, or filling in lubes in the whole motor. There is no touching parts besides the contacts inside a dynamo, unlike cylinder based engines.

So I'm really skeptical.

People please explain to me. Tq.

this might sound too educational and boring, so ignore this if u hate chemistry sweat.gif

basically, zippo liquid is scientifically known/made using naphtha...lightest/most volatile fraction type of hydrocarbon liqiud from petroleum.

In contact with metal, this type of liquid may prevent oxidation of iron - process known as Inhibitor/Corrosion inhibitor.

It's not seeable to naked eyes, but the present of air n oxygen, iron/metal tend to oxidize = rust = extra friction

It's not lubricant but it works to smooth/clean the surface of ball bearing as it's an anti-oxide subtance.

In fact, this is used as cleaning solution for watches parts during servicing (different brand/type, not zippo liquid la).

I guess there are many other ways to smoothen ball bearing and IMO, logically using zippo liquid is kinda acceptable.

correct me if I'm wrong.

Friendly reminder: Please use this product with extra precaution. It has lots of side effect when come into contact with human skin. Do not attempt to drink/swallow/inhale the liquid.

I would accept it as a substance to clean metal.
But most people just follow others, so they don't really understand the after effect.
To me, any moving parts especially metal/iron that makes contact needs to be lubricated to ensure its lifespan.
Zippo liquid cleans bearings, but afterwards it also creates friction and could wear out the ball bearing.
But I guess ball bearings are cheap to replace, so it doesn't matter to most people.

hehehe...cheap to replace? hmm.gif that's depend on indi. pocket size

care to share your method?

I do soak my bearings in zippo liquid for cleaning, then spray with SC 99 and apply some singer oil to it (don't know any cheap lubricant yet - newbies tongue.gif )

color chassis quality is different, it's softer compare normal from the box.

MS used to have color chassis too, it show you are still new~~it come 2 in 1 pack...full chassis(center+nose and parts).

MS is more upgradeable, and more fun... as for me MA is easy as MS, but the launching speed is a bit slower due to it weight.

hmm.gif if it's softer, will it tend to easily break?

I'm getting myself the white MS chassis

it depend on your setting, S2's softness and elasticity let it become the best jump car chassis in town.

yes it's more easy to break...
