sifus, i got questions...

to season the motor how long i need to leave it on?

and where can i get the super speed gear for 1 rotor motor chassis? what is the item code?

buy the old chassis with small wheel can get the gear.

try google motor run in, and see what u can find...

ordering it from the site you found it from ?

besides that? in malaysia dun have?

i see people put bearing with this gear... but i couldn't find the bearing.. does it really exist? or its custom?

yea... was trying to find where i could get it...

QUOTE(david tamiya @ Sep 11 2010, 02:27 AM)
get e car with e small dia wheel and you will get it
for the bearing use the round hole bearing

i know you spend quite sometime looking at the car boxes you will sure know all these ma
GET YOUR BASICS RIGHT NO NEED TO ASK THESE QUESTIONS HERE PLEASE USE MORE EFFORT DONT EXPECT SPOON FEED AS IT IS NOT GOOD FOR YOU COS WITHOUT TRYING YOU ARE ALWASY AT 0% FOREVER

bro, u have to understand my situation... i've been like never touch mini 4wd for like a decad... those times and now are totally different... everything now is MS pro.. availability also MS PRO... u say i spent time looking at the boxes... yea, BUT i dun read japanese.. though it looks the same as the part i'm looking for i could be not the on i want... its in japanese and i wont know the gear ratio...maybe it higher.. and i dint know those ball bearing can be used cuz i thought it might not be suitable or something... anyway thx for the info... appreciated it

i'm not expecting spoon feed i'm just clarifying...i appreciate those who willing to explain to me..thx

i doubt the same time theory
there is always momentum to be considered
power of the motor and battery also plays a big part

true true... like the test that the video shown and what u have said before.. aerodynamics also play a big role in this

-power of gravity means is not just a good idea, it's the law...hahaha...
-motor,power, wheel spinning can only change the position or action on air, so it bring in diff cover shape which bring diff effect on air resistance...david, you are in this level already...hahaha

does having a lower car height helps in aerodynamics? like the a F1 car..

stability it does . aerodynamically ar, need to test ...

cuz like F1 they have 'almost-touch-ground' height so that it could cut through air and produce downforce for the car.. correct me if i'm wrong hmm.gif

win . but then lower the car , its a bit more stable .

QUOTE(lolhalol @ Sep 18 2010, 09:39 PM)
lower car is not = to beter speed.
a properly setup car with the right choices in tires size , rollers, and angle = to better speed.


Added on September 18, 2010, 9:38 pm

in f1 they have diffusers . tamiya dun have..
*
hmm i thought without diffuser also a lower car could cut through air better than a higher one... and yea like sonic said more stable cuz less air will travel underneath the car..

there is two kinds of main kinds. one is teh cover is low. one is the car is physically low. Eg. Go see jap speed frp cars. most are not lowered. in-fact most have a high ride height due to the 35mm tires they use. but they use low covers . Physically lowered cars are difficult to get right , but if u get it right there are advantages  . ( im talking about MS chassis ) . 

btw its is not stable because of the air under the car. it is the lower center of gravity.


Added on September 18, 2010, 10:07 pmbtw using f1 as example not really that great if u are talking aero dynamics. F1 cars a highly complicated and most times their aero body work comes in packages. Just the diffuser alone , it is only a very small part of it..

hmm hmm.gif maybe mini 4wd just rely on good aerodynamic body i guess...

i think is better to do aerodynamic for decreasing air resistance when moving forward... however, i don't think aerodynamic producing down force will suitable for mini 4wd( speed car).

1. F1 need it for corner, because F1 using steering to turning corner... mini 4wd using track to turn, so why mini 4wd need downforce to corner??

2. if you study more, you will know aerodynamic might produce downforce, over done will slow down the F1 car on straight...do you think you wan't your mini 4wd to slowdown on straight?

3. racing is all about balance....

4. i actually let my car high let the air go into the bottom...also, the cover actually produce lifting force, in this case, i no need to cut a lot from my car... the lifting force help to reduce the weight...and i can maintain my car strengh...

If you talk about aerodynamic for mini 4wd, i think this is better and more useful for mini4wd... speed car only... jump car might be diff story...
*
haha my bad i'm like more referring to technical type... cuz we want to jump properly during jumps... for speed without jumps of cuz we dun use dowforce cuz it will slow the car down, more better we find a way to make the car cut through the air(aerodynamic)...
erm how does the cover produce lifting force?? first time hearing this, mine to explain a little more detail? notworthy.gif

QUOTE(choycp @ Sep 19 2010, 11:06 AM)
Guys...let's play super technical track. Why so obsessd with speed?

Different covers have different effect. U have to try all of them to know the differences.just looking at them and coming up with theories just won't cut it.

For me cars with smaller diameter is easier to set for jumps. Large diameter is suitable for speed. BUT whatever it is, I have been proven wrong by the sifus here a lot of times.
*
haha thats why most of the cars i see using medium size.. not too big not too small, for technical la but for speed all hentam super large only...
