Track Layout

Final Race

Sure, next time i ask my friend to help.

Anybody do new track record already??

did u guys notice how damper works?
see which damper goes 'up' first and it will push your car up not down
nowonder i saw some people [including me] put the damper dekat tengah tengah o

i found out why tamiya make their roller extension weird shape.



let say the car is turning to the left .
as u guys can see,the yellow screw act like a pivot point where the red screw is in stress.If guys see the direction of stress of the left roller,is backwards. BUT because of the position of the extension, the stress on the red screw is forward. Thus force acted on the car to move forward.

baru abis baca physics ma

I can explain that in theory la


as u can see,the white box is contact area of rear roller with the track.
assuming the track is clean, and car is moving at constant speed.
we can conclude that larger surface area contact with the track,the more friction exerted on the track
.But,if we use small surface area that contact with the track [Eg. 19mm roller ]the less friction exerted on the track

However,some variable have to be concern >
1: Track is not always smooth,always have the black tape.Thus increase the friction
2: The position of the roller effect the force exerted on the track is different as shown in picture below>

3: The less surface area contact with the track,the more pressure the roller is.This is why most of us that use 19mm roller put two frp to make it harder to bend as most of us trying to reduce the contact area of the roller but at the same time increase it pressure. This can be explain as>

Formula Pressure Form 4

Mathematically:

p = F/A

where:

p is the pressure,
F is the normal force,
A is the area.

Silap.if depan terlampau berat,assuming bukan mass damper and weight plate tu,tekanan bukan ke bawah sebab inertia kereta 4wd kehadapan bukan kebawah,so,naikan berat kerata,sama macam bro nak terbangkan kereta tu lagi tinggi.Thats why banyak sifu cuba turunkan berat kereta.mass damper kat belakang tolong tolak nose kereta tu kebawah macam bro matt4wd nyer kereta,tgk how kereta dia fly masa race hari tu?macam tu la.

Theory inertia>
The mass of a body determines the momentum P of the body at given velocity v; it is a proportionality factor in the formula:

P = mv

The factor m is referred to as inertial mass.



Ye la,kena study kot 5 hari nie =,=
haha

go on thursday la,i will be there with my girlfriend

aiyoo,all sifu will be there
need to clean my bearing la,scare sifu cars will hit my car HAAH

eleh,dont joke la bro,my bearing all tak boleh guna already
Quote from teoh ' i punya roller tak smooth ma'

Aiyo,PENGGUNA sudah complain.nanti saya fix jika ada masa =D

omg,i can see big tamiya stickers !!i want one =D

apai nak buat stand tinggi camtu ke?HAHA

matt, mind to teach me how u clean your roller?
sooo smooth until cant hear any 'kreak kreak'


To all 4WD racer, please take care of your stuff.Ada org gatal tangan curi timer.aiyo.

let me share something with u guys.
when i was 12,i always go to toycity sunway piramid where they have onstage track.
sometimes,i put my box near the 'pitstop' for 4wd and i ask the worker to take care of the box.
unfortunately,that f****** worker took 5 frp's ,two sets of tyre, 4 sets of long screw and 6 aluminium roller's.
it cost me alot and i report to my dad,and my dad report it to the shop .after that,that guy tak kerja at toy city anymore.
u see,when people are obsessed with something, they would do such thing. and right now in t.u, everybody u can trust, thats what i like in t.u. but,not the people that use T.u as shortcut
