literallly cannot find unless you are willing to pay high price , especially the proto emperor zx .. .

That's bad..nowdays so many people keep ask about Proto Emperor ZX..im also hunt that model but no luck..hmm..

for me, use for inner suspension. btw u got this item??
nak beli    

Grab 2 sets of this Basic Tune up set.. Item no. 15435

Double the front and rear plate for better strength..

Next, ball bearings for wheels, ball bearing rollers, motors, front and rear brakes.

Use stock wheels first as the stock medium diameter wheel with the low profile tires are pretty stable.

For brakes, try the sponge one first. Bila dah pandai nanti you can try the FRP plate one. 

Alamak. Bought the standard one oredi. Arghhh....

The ar one looks nicer but the 9mm mount easier to break. Either one must stack it or double so that it last longer.
The zippo fluid helps to wash the oil so that ot has less friction internal but at the cost of wearing out the bearing. Oil are sticky hence racer wash it away but it also means the bearing at easier to spoil or stuck

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

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.

hehehe...cheap to replace?  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 )

most ball bearing come with protective grease to prevent it rush, so new bearing usually we will clean it with zippo or contact cleaner to wash out the grease, the grease is good for industrail usage but not for speed purpose like mini 4wd.

after cleanning, we will drip some bearing oil, this is important not just the lifespend of the bearing, but it will take more load, and spin faster when it come with force.

wow Dasa! you got stock ah? are you selling them?    local retailers dont have it. HLJ pun takda la these colourful MS Chassis
