lighter is better?? i don't think so, when car go light, unless you have tire that can provide high grip which need less weight to provide friction, otherwise, you will found that your wheel actually not doing it job.

meanwhile, tire is actually the only thing contact with track that made your car running on the track...hahaha...

double side tape the tyre

hehe. never thought stock motor can perform for something..

hmm...too light also not good i think. need to consider power:weight ratio 1st..grip also needed, so might be need to use bodyshell (cover) that can generate downforce to the car.


r u talking about painting the whole chassis or cover only? if whole chassis, definitely will add 2-4g...but still ok la.no problem with dat.

HIHI...I just bought the sanyo eneloop rechargeable batteries recently...but the charger makes some hissing sound...
for you guys who are using it, do you experience that too???

sorry beans..i'm using GP rechargeable only.. 1600 n 2700. dunno what happened to your batts.

FYI all, this is the hand drill i'm talking about...

n also the results on my chassis.


Attached thumbnail(s)

mio, hand drill tu where you brought it ?

NG,
daiso japan, the curve (2nd floor, near to al-ikhsan sport store there)

ohh i also need to get one set.. what sizes do they have available?

not really sure..but what I've saw last time they got 1.5mm, 2.0mm, 2.5mm. rm5 each.

timed my fmx just now with gp1600+sprint dash courtesy of chris+large arched tires (took them out b4 taking the photo)

before that i only managed 17.56 with the trimmed tires.

from my research, the large dia arched tires definitely have more top speed.

you mean th tires that come with the dyna hawk ar ?

nope. is that thin chinese guy's special arched tires...

ng, i think light cars shud be an advantage during a long track race due to lesser battery consumption hence better endurance, which also means longer lasting battery usage throughout the race (clocking consistent lapse time).. but ur right bout tire grip.. however, with de weight of the batteries, i think it shud be sufficient to press the tire down to create more grip..

nway, juz my way of seeing things.. cheers..

lol

then again , aerodynamics would play a role if the car is light weight .

surely lighter better, but ppl are too concern on weight and forget about the tire which actually more important. a correct tire setting bring huge diff. tamiya tire normally very hard, the car actually keep on jumping when it running, motor's power actually unable transfer to the ground.

if you can solve tire problem. weight can come after it.

that is what i wanna say.

mr junichi got come by few days ago leh....

@szngszng yes u are right, no matter how fast and smooth the car is, if at high speed the tire cannot grip the track also no use. thats why u and i that day discuss about the reston setup, now i found a new setup, share with u soon. btw ur pic is ready...

we need reston's "soft" and rubber's "grip"....

unfortunately, reston is not that grip on used track... or else it will be a good choice, light and power..hahaha...

imo, the closest would be the thinned down rubber tire.. i think .. else can use brigdestone tyres...lol
