really happy that i got to race again since last year lucky still can win a prize . well congrats to my fellow racer mr eelan for winning this race.
been a bz body this race helping with the timer and stuff , from what i see there are really racers that will do anything to win as i see this really going to spoil the race sooner or later really regret to see this with my own eyes like using 2wd in a 4wd race boosting battery yeah the rule did nnot say no to boosting but i think its a bit unfair to newcomers who dont know how to win........ will be talking to the oganizer about this situation we will see what to do on october final race , yeah i will be racing 2 hahah long time no race hand itchy already if all is well will be coming for the sept race by then hope to see the (winning) be more fair but as i say everyone will have their right or wrong to defend in this situation.
cheers and happy racing

David, is good to voice up those issue...

See the real sportamn ship in you ane your group.... what u mean

he means that you and your group dont cheat, and show real sportmanship.

haha thank you then

Hi David,

Nice to see you the last weekend race and congrats to you and also to Eelen - won the race.
Boosting of the battery has been in the races since Tai Seng Corporations 4wd mini race till now.
This always happens when battery is not supplied by the official and moreover not stated in the rules.
As for the newcomers, regrets to say that I also been thru that since Tai Seng 4wd mini race and long way to learn all the chassis and settings which is more suitable for that particular track set-up.
Set up the technical track that stops people from boosting the battery.

The Final race - should be strict and all cars & motor's to be checked before the race start.

Hope to see you again in Singapore ! and also not forgetting the KL 4wd mini racers.

yes really hapy that u have point out the problem , as what i see the racers in singapore are less than what i see when in 2006
i hope that u can try to help newcomers also i think u are happy to do that right , at least they got chance then their interest will grow then more racermeans more races , regretfully to say what i am seeing in singapore had heappen in malaysia which have killed mini4wd racing here.
i am happy about your dedication to this hobby really hoping to race with u soon hahha no more challenge in malaysia.
so i hope that u can just spend some time looking at the beginners give them a tip or 2 so at leas they dont felt left oout in this race , i will also ask eelan to do the same to bring back mini4wd racing in singapore not just to see the same people racing all the time.

yeah... That's the spirit..... Real sportsman... Sure like to race with you in KL one of these day when I visit my relatives there...

BTW, I race for so long..also dun really know how to make a car setting faster or slower...

There are general guidelines over the net...

But when I tried to modify them, they perform otherwise...

Many factors .. to consider...

hmm , maybe i should go there once again

Let me know if you interested ..
We planning to going down again at September ...

Hi David,
The best was in SUN TEC race .. it was the biggest track ever set-up and the winning car came in about 45secs.
The biggest crowds was in Plaza Singapura race and it was about a few hundred racers and 2 separates tracks
was set-up. ( one for open race and the other for tamiya shop racer's to complete each other )

To promote Tamiya 4wd mini, Stargek has to organize more races at least once a month and more races during
the school holidays.

Thanks for compliments ! I am glad that you also keeping this hobby alive over your side.
For the newcomer's , they are always welcome to ask and share their views on the modications & settings.

Last 2 years, Stargek has organize more races than than this year.... it is a pity that they don't keep having races since
beginning this year.

hahah that was long time ago maybe i still beginner.
happy that u are willing to help .
sorry ar but that day i think u boosted the battery right correct me if i am wrong,
i will be coming down this september just a suggestion we just race witout boosting just to enjoy racing among each other see we got chance to win racers boosting and i think we still stand a chance also give other chance lah hehehe
so ok or not with my offer hope to really enjoy racing with u and maybe tamiya xiao also can join

dont say race la got chance come to kl just visit me at the shop we can always talk mini4wd
got quite a big track in the shop so u can just bring car for testing see what improvement we can do

Bro, I dun stay in Malaysia.... But.. I have been to your shop end last year.... Your track really BIG.... To bad I did not bring my car... as it was a family trip and I promise my wife ..."No Tamiya"....

Manage to buy some spare parts and got some discount from your colleagues

I promise to bring one Tamiya car when I go on my next trip... ... Help to keep this secret from my wife ok..

no problem lah still got chance too bad i did not get to meet u last year , if all is well we will meet again in sept u num7 that day right

Hee...hee... Ya lor.... Busy testing my cars...

See you on Sep then..

In all the races , I always testing out a few cars first with a slower motor and once they having no problems to complete the course.
After that I will change motors for a faster timings and boosting battery only for the speed track set up (when everyone started boosting it )hehehe
On that day, after a few tries on my car and change to hyper pro motor and it's came in the fastest time and after that I was setting my son car & my buddy car with boosting battery charge higher than the new battery charge and hopefully their can take that fast speeds...afterall u can see most of the regular racer's are boosting their batteries. My advice -not to any how boost battery it's might do more to your motor and also might damage
your car. Have to understand and observe the car performance..if not stable during the hump & change lane sections then dont keep boosting the battery.
I am glad that you able come to Singapore in the September race and hope see you soon.
No problem at all ! hope that our cars can races all the way to the top 10 position.

Well, generally i dont see a point @ boosting batteries basically learn nothing. (Kinda unskilled IMHO) In the end of the day is the setting of the car not the batteries. If you're are there means you're are there. Please note that not EVERYONE boost their batteries and not all of them know how to do it. So stop stereotyping and give yourself reason to boost. Im not trying to have war, im just tellng you off. Thank You.

how to boost battery....???never knew battery also can boost...whats the effect after boosting battery...???

happy to hear that so i see u in sept this is going to be fun hahahh long time dont have this kind of thrill already so all the best la
(yeah sad to say motor and car is not a problem to me last race i bring around a dozen of new hyper :hehe:and i did not boost to get 19sec so i am proud of myself hhehehe)

wat the fastest timing recent race???

Salute..... Hope can catch with you the next race.... Cheers!!

Yes ! I am agree with you boosting batteries - does not means the car can complete the course.
Please do not get angry over comments and did not means to you ! so please cool down ! I have bracket it up my sentence.
By the way, please read my advice on my earlier forums and I have mentioned the car settings is more important !
I dont offend you at all and I does not required you to tell me off !

Hi David,
My car timing also using hyper pro motor without boosting batteries lah !
Same to you ...wishing all the racers all the best ! Keep on change the settings of the car.
See you in September race !

As an adult, we responsible of wat we've done, not keep dragging everyone into the water.
Thing started when david tamiya ask u if u got boost battery, answer can be simple as "Yes" or "No", but u keep telling the whole world that other racers also boosting their batteries. I tink is not so rite. Be a responsible racers & win the race with pride. if a racer won the race by cheating doesn't mean we gotto follow. (Of course i dun mean boosting battery is a cheating act coz rule nv state we r not allow to boost battery.) Pardon me if i unintentional offend anybody. Peace!

Right.... Show all of us what our cars are made of in Sep.... Already come out with a few new cars....

Hi 5WD,

I am not dragging any body and I have answer the questions to David ! n why you so offended !
Please read my earlier forums ok ! I always race my car with pride and I dont go around the world to complain whatsever is unfair.
By the way, are you been racing 4wd mini since Stargek started organize the races the past 2 years ?
As for me, most of the time is boosting back the used batteries back to their normal charge and this help to save some money on battaries cost...
and hope you understand this !
Dont you worry and I will answer all my actions that I have done as 4wd mini racer's.

Hope this forums is open discussions on 4wd mini car and please do not give negative feedbacks....

HI Uncletamiya,

Gotto make it simple. Wat I want to say is RESPONSIBLE. Quoted fr ur previous msg, (when everyone started boosting it ) & afterall u can see most of the regular racer's are boosting their batteries.. R u trying to telling ppl tat u r not alone? Or juz want to find some supporting points to prove tat boosting battery is nothing wrong coz majority win??

And i'm not making use of tis topic to declare war, my intention is juz want to tell u tat be a responsible racer. When ppl question u dun simply point ur finger out & push everything away. I apologise if u feel offended & Happy Racing to all racers here!!

p/s: If a person juz accept positive feedback & reject negative feedback, there will be no improvement. My point of view.

tamiyaxiao happy that u have come out with new car this will be interesting hahah nice talking to u on raceday

Added on July 19, 2008, 6:09 pm
uncletamiya just some question cos we here dont boost so hope u can just let me know , how much batt u use to boost cos long long time ago i also got boost but i charge with charger so can u tell the difference if u have tried it i just need it for my reference cos i think i will try to join more races in singapore and bosting is 1 of the way racers do in singapore (also want to try to win )
(all places have its written and untold rules to follow it and exell on these terms make me fell crazy about racing mini4wd) so uncletamiya i will be coming for u hahah (try to beat your timing)

Ya... ya.... I used to boost battery... but dun know what is the right way...... can share ??

Hi David,
Just because you ask about boosting batteries and it's cause many people unhappy !
* If in any ways that offend those racer's did not boost batteries and I will apologise !

I know in Malaysia race don't boost batteries ... in fact I told you before last year ! remember !
Boosting batteries does not means your car can win the race.

Fyi, understand the layout of the tracks then you decide for yourself .. whether it is sensible or not !
Most importantly is to observe your car on first trial run on the course.
Please do not think that in Singapore race always can boost batteries and the organiser's will states in the rules or some changes to it.
At times when it is a technical track , you have to drain some charge before you let your car on the track.

My advise do not have that mind set to come after my car's cause win or lose is part the race .... most important to understand
those car's with a great speed and so steady that able to clear during difficult sections and try to understand & found a solutions to it.

>david tamiya,
Thank you!

>tamiyaxiao,
Thank you!
hehe I try my best for the upcoming race, I am ok if got defeated will learn things from it.

>UNCLETAMIYA,
Thank you!

I think boosting battery is a standard practice in Singapore from last time until now. To me, no right or wrong. However, since it is a "PRO TOUR RACE" I think take it as a challenge race without boosting battery. End of the day, you will be racing in Japan, not Singapore/ Malaysia.

i think i have enough experiance to know what track i am racing in so no worries i will not boost blindly i am just asking to know more bout boosting.
well in my case i see that u have a fast and stable car so i set my target to beat your timing as a motivation to do better i dont think that is a negetive thing to do right u also have your targets in a race right if u cant make it this race it will be more challenging for the next which this is a point for u to improve and do better correct me if i am wrong cos to me this is ok if someone come after me it will drive me to do better
if i were to offend other racer bout boosting just feel free to tell me off then we just see who better in the coming race or a 1 to 1 fight also can (with hand and leg)
