Added on July 31, 2010, 2:38 ambtw any reason why 850 ? i think the 830 is beter coz the insides is florine coated.

bro , 850 and 830 is teh same size .

the first number represents the outer diameter, the second represents the inner diameter. ex. 9mm would be 950

11mm is 1150 and so on.

Who ever think it's easy... please to let you know this is a clockwise layout... so please ready your car for this month race...

i don't think the car can made it... diff type of layout...1 car can't suit all layout...

blue avante, im not sure yet....but yellow already come..haha

my car here, but for sure cannot pass hi-speed LC at TU.. 
need to do sumthing to figure it out.. 

thats the downside of that chassis .. but it makes up in weight

just be very careful when screwing the holes. hehehehe..  make sure the screw is really straight. if its really hard to screw it in. means its not right aledi. a nice hole is when it can go in really easy but also when fully screwed it is tight..
haha sorry the above post sounds very very 18+hahah

lol. i dunno then. u using washers ? i never cracked the screw hole before even when using old chasis. break the whole nose completely alot of times but never just teh screw hole. haha

normally we just clean up the rollers+bearings n let it dust-free..so it can spin smoothly .bcoz tamiya RC cleaner and elkay is not oil based, so it is allowed at TU for rempit n during race. some type of cleaners are oil based, so it can caused track+other cars dirty n collectiing dust. dat kind of cleaners are BANNED. 

to all Muslims who fasting today, SLAMAT BERBUKA PUASA.
lets go buy food at bazar!!! hehehe

yeah..i noticed your VS setup juz like mine in previous race. but u need to test at track 1st bcoz that aloy frp might hit the track when cornering, rather than your rollers.
maybe u can bring fwd that roller n use 2nd hole, not the 1st hole...
advice only 

my car?? RIP already (rest in peace). i juz keep the chassis. i'm prefer using MS

good to know junichi not satisfied with the result... let's aim higher....

-smoother car can do better speed
*motor
*gear
*wheel
*weight
*bearing
*terminal

-roller setting can achieve faster cornering
*width/narrow
*long/short
*high/low
*roller friction
*amount of roller

-proper braking can bring us back to timer...

yes, providing that the car only has 6 rollers... there would be 2 rollers at the rear of the car ( one roller one side each) , front would be left side 2 rollers and right side 1 rolller and the 19' roller in the middle.

which engine is the best?

we have sales starting tomorrow for mini4wd cars lol

yeah the tools are expensive but lucky me i got some old tools from my cousin
cause he didnt play already. Although its old but still usable 
WoW  
U got keep a record?
