how can i increase the voltage supply........by increasing the no. of cells???
if so,then how much cells???.....can i use duracell?....making a battery pack means connecting all cells in series???
but that's a problem......when there energy finishes,I'll have to buy new cells again and again....any way to overcome this?

i have a gas vehicle for sale<a bit expensive>
would you like to buy it??
its pics are there in cars section in the post "some more pics of my collection"<black one>
I'll be back.

I'm interested in electric cars only coz i don't have knowledge about gas cars and their fuel...

traxxrc1

even no one near me,
but i take them alone at some lonely place and have fun
I'll be back.

are their any cells or batteries which I can recharge again and again and again...
if so,then how many times can i recharge them and the cost?
when i go to d shop,what should i say?
"i want a good quality brushed motor for my rc car,here see this(i'll show my rc car and the motor)" ??

how to make a race track for rc cars and how to perform different tricks with your rc cars?
if i buy a new good quality brushed motor,how much will my top speed and acceleration be affected?
how much would be top speed?
can i supply exactly 7.2 volts or more?

now it depends on where u live, most electronics market will have motor but it depends whether your car has a better motor or the new one would be better, in most cases they both will be same quality chinese motors.

high quality brushed motors are RC car brushed motors. they are much efficient than regular motors.
try findind if u can get one of your size and voltage requiremnts. a brushed one will cost around Rs.700 while a brushless for around Rs.1600.
however almost all rc motor are designed for 7.2V .
they would not perform very good at your cars voltage

I'll go for a brushed one as that goes with my budget....
how can i incrase the voltage...by increasing the no. of cells?
making a battery pack means making a pack of cells by connecting them in series?
how much will the top speed and acceleration be affected?
how much will be the top speed?
when i go the shop,what will i say to the shopkeeper..
"I want a good quality brushed motor,here see this(I'll show my rc car and it's motor so that he can see the size)"..?

nice suggestion karthik, saw a couple of videos on youtube for the same

My Introduction-
I am 17 Years old, born in bristol(UK), lived 2 years in US (San Antonio,texas), then shifted to homecountry, and here from last 12 years.
Right now i am studying in class 12
Have been in this hobby from childhood since i was born in an environment in which you can find a RC car every next door.
Whatever i know is my SELF GAINED EXPERIENCE

When you want to buy batteries, go to reliance digital, ask them for camera cells of NiMh type(AA size), each of 1.2V, and connect them in series in desierd no.(see your science book to know about series connection).

I'll be back.

and ya KODAK sells a pack for 500 rupees wherein they have 4 AA NiMh rechargeable cells with a charger included, try finding it

try upgrading your car one by one, step after step
I'll be back.

with the new battery first of all your runtime will incerase, also it will increase the speed by 3-5kmph.

dont even think to put a 7.2V pack.

if you buy from local electronics shops---
take the motor out of the car, go to the shop and ask him to give you a motor of same size and voltage but some better rpm (he probably might know its rpm), fix the capacitor from the old motor to the new motor(it is a brown color disc b/w the 2 terminals of your motor) as the new motor might not have one.

If you buy from a RC hobby shop-
tell him the dimension of your motor, and take the one he gives you,he might ask you about the turns of motor that you require, try getting the highest turn motor because thats what your car circuit can support, lower turn=faster speed but your cars' circuit will burn up with that motor.
the rc motor will come with every thing like the capacitor presoldered

i can t tell you about a new battery pack untill you tell me what is the voltage of the car rght now.
I STILL SUGGEST TRY SAVING SOME MONEY AND BUY A USED ELECTRIC FOR ABOUT 4000

this will do atleast 30kmph,will be highly upgradeable, easy to do stunts and tricks, and will not look CHILDISH
I'll be back.

i gotta go somewhere....i won't be here for two days..
i'll tell d details when i return.

Why would you want to waste your time and money on a 500Rs car. Forget it and get a hobby grade RC car. This toy is not worth your effort.

I might sound like a moderator, but it is not particularly pleasing to see 'n' number of replies in such a short time frame !!

Can you not use the edit/modify function ?

I don't think its worth it modifying these cheap chinese cars.. The maximum I would do is increase the voltage to the motor.. But even with this mod you should be careful as there are chances of frying the receiver chip (generic RX2 chip).. Somewhere on the net (don't remember where) I had read about this mod where the input voltage is increased by increasing the number of cells and a voltage regulator is fit to the input of the chip to isolate it from the higher voltage..
