RC India

Hi! I am Sam(Sumit) from Faridabad......
I have bought a cheap Rs. 500 rc electric car and I want to improve its performance.
I wish to increase it's speed(i want it very very fast) and want to drift.
how much would a brushless motor cost and where can i buy it near my home?
how much battery power would i need to increase its speed.
i don't have much knowledge ,so please..."no technical names"
my budget is Rs. 700 ....
please tell in detail.......
you can contact me on

Welcome to RC India :)

It would be really surprising if you found a brushless motors and the brushless speed controller (ESC) to go with it for that budget.  Plus, motors are chosen based on purpose and size of the vehicle, so without such details, no one can even make guesses.

Also, it seems that you have posted this question within 20 minutes of registering here.  If you take bit of time and go through our "Gems" list, or just search the forum for RC shops, you will find our "mega list of RC shops", which would be useful to you.

first thing -
your vehicle is a toy grade. so you cannot upgraade it with ease as it is nearly impossible to find a motor of the that size.
brushless motor will cost at least 1500 rupees and esc for atleast 1800,
so noway near your budget
even then if u put a brushless motor init your cars gears and all other parts will come out of the body.
also u do anything but you wont be able to hit even 20kmph with any toygrade.
what i can suggest you is get some AA size NiMh and make your own battery pack to provide better current.(use high quality one like from SONY made for digi cameras), because your car might have come with cheap quality NiCd with extremely low capacity
this battery will cost around 500 rupees.

one more thing -
if you have good knowledge about electronics try designing a circuit of your own with a higher voltage capability and use it with your same stock motor.(most probably your motor can handle upto 6V easily).

think of getting a new motor only after you have increased the voltage with a  new circuit

dont put a ver high voltage battery in it(7.2/8.4V) as your  circuit will burn.

your car might be using a 4 cell battery , what i can say is that most probably your car can handle upto 5 cell battery(6V). that would increase performance a little
some special tips that wont cost you a buck---
*lubricate your cars gears with a engine oil
*reduce the weight of your car by removing extra show parts
*breakin your motor---see this post
    http://www.rcindia.org/cars/electric-motor-breakin-guide/
*if your tires have spike or some irregularities, smoothen them up, or get new tires which are   plain.
*shift your battery from undermount to the front part of your car, this will make it drift nicely
* Get a pinion gear of your motor's shaft size with more no. of teeths than the one you are using right now.
this can greatly increase the speed by compromising with accelereation
*properly wire your circuit, replace thin wires on the circuit with thick wires
<a properly wired brushed motor can outperform a poorly wired brushless motor>

BY ALL THESE STEPS YOU CAN SPEDEN UP YOUR CAR BY 20-30%

i personnaly found these trick and made by first toy monster truck hit around 20kmph
look, there are no special controls for drifting a hobby grade vehicle as well, they are drifted by the massive acceleration they have and the slick tyres which provide a lot less friction

Low friction + High Power = drift
burnout never possible with that quality of car
rear part, bottom(probably white coloured disc with tooths/spikes)
just where the motor head<pinion gear> is situated
noway for that,
either you can have high speed or more torque,

only way is that get a high quality motor
high quality can be a brushed motor with a better winding
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 dont know about faridabad, i live in ghaziabad and can tell u about delhi,
buy it online if you really want to
one thing i can tell you is that instead of spending your money here,

SAVE,

and buy a used electric vehicle(this is the cheapest)

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>
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).
they would be rechargeable
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
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.
are you running your car on dry cells? how many?
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

even then if u put a brushless motor init your cars gears and all other parts will come out of the body.
also u do anything but you wont be able to hit even 20kmph with any toygrade.

Even I started like this.My budget was 15k,beefed up to 25k after a lot of pleading with my dad.

A bl motor would kill your car.As Arpit said,the batteries seem to be the only way.

hey gandhar, your initial budget was 15k mann, his is ".7k"

BTW gandhar did you got your car??

should be getting it in 10 days or so.Will order it very soon.Waiting for traxxas guys to confirm that it is in stock.

which one are you looking for?

buddy my tires are smooth but I don't know the technique of drifting.
I have only two controls on my remote......one for direction(left and right only) and forward and backward

and is it possible to make a burn-out????

look, there are no special controls for drifting a hobby grade vehicle as well, they are drifted by the massive acceleration they have and the slick tyres which provide a lot less friction

Low friction + High Power = drift

burnout never possible with that quality of car.

where are the gears of the rc car..
any way to increase acceleration without compromising with top speed...?
any way to increase speed+acceleration ????

rear part, bottom(probably white coloured disc with tooths/spikes)
just where the motor head<pinion gear> is situated

noway for that,
either you can have high speed or more torque,

only way is that get a high quality motor

where can i get a high quality motor and how much will it cost..

i think that by 'high quality' u mean brushless

high quality can be a brushed motor with a better winding

where can i get it and how will it cost...
how much will both a high quality brushed motor and brushless cost in Faridabad...and any nearby store?

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.

and buy a used electric vehicle(this is the cheapest)

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>

no one plays with rc cars near my home :(

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

even no one near me,
but i take them alone at some lonely place and have fun

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?

how old r u?
you sound expert..
I'm 15,in 10th

Tape your wheels and get it to drift !

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

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 will keep that in mind. thanks karthik

can i use this motor?
http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=4908

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..

what's this voltage regulator?
and if i don't mod this cheap car,then which car should i modify????
how much will it cost..
is there  any car that can hit 40kmph,has great acceleration...if yes,then how much will it cost?

You will just waste time and money modding a cheap car.I also think that only batteries are an option.Try a used car.

what's a voltage regulator??
if i don't mod this cheap car then,which car should i mod?
is there any car that can hit 40 kmph and has gr8 acceleration?
if yes,then how much will it cost in india???????
NOTE : - I'm running low on money

You have to be aware of a reality in RC, especially in the context of India.  Any decent quality RC equipment still comes with an entry barrier in terms of price (in India)... that is one big reason why this hobby is still not that widespread in our country.

You are right.
moreover,our parents think that rc cars are just toys that are meant for kids.
when we grow up and want to have fun with rc cars again.....pleople laugh at us....
i don't think that it will cost anything less than 2500 rupees

Very true.. But I managed to convince my dad to buy a kit because it teaches me about various parts of the car like the diff., gears and stuff... (Mainly because he's an engineer)

Try to convince your parents to get you a nicer car... Take them to the track once and have them talk to the  people there...
2500 is slim.. You may be able to get an 18th scale car or a Mini Z.. Not too sure about them though

sorry to say but its a common perception that small cars are very cheap.
an 18th scale car will not be anyting less than $100
in my case i can explain you with Losi Remunitor/Remunition
its priced at $150 being a 16th scale car

Wrong thread to ask this question.

Still, the price depends.. check www.traxxas.in

Hai Friend,its too easy to improve the performance of a "cheap car"..for this you must need some good knowledge in Electronics and Mechanics.we all consider many toys as "cheap toys" but my experience shows mostly not.i always collect possible scraped toys from homes and scrapyards,and most of them are too good for their value.i made many proportional servos with many toy gear boxes,some are too powerful in working. i used many such servos in sail boats to operate the sail.
to increase, ( to alter, more clearly), the performance of a toy grade rc car, you must consider the motor at first.all toy grade motors will be, mostly, based on 6 volts,DC, and in to 700 or 800 mA maximum.the driving circuits also will be based on these calculations.for example, the motor driving circuit of a 6 volts based toy car will be, mostly  based on 8050 and 8550 transistors.so the chosen battery pack also will be within 500 mA range by the manufacturer.in some toys we can see a 1, or 4.5 Ohms high watt resistor in power lines, to reduce the current to the main circuit in a motor stall.
in some good performance cars we can see some moderately powerful transistors like 882 pairs.but anyhow these circuits are intended for lower performance. and most of the toy grade RCs are based on RX 2B to RX 6B MCPs.

the RX 2B MCP is very versatile, and if you use a transistorized network to it, you can get proportional control,but need thorough knowledge in applied Electronics. any how our point of view is to increase the performance in an inexpensive way.so, any how we must consider the motor. most of the toy based motors will be less powerful,and brushed with flimsy brushes.what you have to do is, first of all, altering the brush.you can do it simply, by collecting a pair of starter motor brush set, of a Kinetic Honda scooter, or Honda Activa, or from any motor bike based on 12 volts battery electrics. open the back cover of the motor. so we will see the brush panels, with two flimsy fingers.then cut two tiny pieces from the brush set, of the starter motor, by an hacksaw blade, and grind it off up to the size, that fits the fingers of the intended motor.make a thin ridge at the back of the grinded piece, so, you can simply insert the piece in between the gaps of the real brush. if not, you can simply drill a simple hole to the fingers, and can fix the brush in place.

after checking for smooth operation, you can go for the next step.if you are willing to get a high performance, you can simply alter the main windings with new winding wires, according to your voltage, but make sure the plastic insulators will with stand the excess heat generated by the new windings.you can add high grade panels to the armature walls, so it will absorb excess heat to a great extent.motor winding is a painstaking proses, and it will take time , precision, and patience.its not necessary to alter the brush or winding if you are looking for a moderate performance.after correcting the motor, you can make a simple speed controller, based on PWM, is simple, can operate by a pulse generated by the TX, or can generate itself, in a preset mode, as the input voltage energized by the TX, on RX, then the input voltage triggers the PW Modulator,giving an instant start to the motor.you can use N channel and P channel MOSFET s, for rev and ffd.

and can use a weightless battery, can make at home, or can buy from any shop, or hobby shop, now is cheaper, you can find many reputed suppliers here in our reputed Forum.
here i am adding my "cheap toy car", is got from one of my friend, who is running a duty paid shop, in Thalassery town,and he always collect, and shifts damaged toys and stuffs for me.this car was put in a corner with waste, as it's battery pack dead.i gave him nothing, but he told me its price as 400/-Rs.i dismantled it at home, reworked on motor, for 7.2 volt specs,replaced motor bearings with brass bushes from walkman capstan bearing,brushes from scooter starter motor.added a PWM based motor controller.at 7.2 volts she is a real drifter..i spend nothing as extra ordinary..working on same TX and RX, same wheels, same steering mechanism,same differential,same body..nothing is removed,and hand painted with ordinary enamel paint.i hide this car from my son, Kundoo,because he cries in big mouth whenever he see this car..i an not much interested to spoil it's finish..as i like this car much.

you can see the simple motor controller inside here, i added this because the actual circuit will not with stand the current rating of the reworked motor.a simple addition..done..

at beginning i made a battery pack, at home by 3A batteries, and later replaced with LiPoly, in to 7.2 volts,for added running time.when i was completed this rework, the LiPoly batteries were expensive, but now its inexpensive than a battery pack of Ni Mh, in same rating.6 NiMh cells from a reputed company will cost 600X3 (600Rs for two), 1800/-Rs,but a LiPoly will less than 900/-Rs.so will work well..i will add a good video by tomorrow, revealing all internals,and performance..so you can see how simple it is to increase the performance of a toy grade rc car.. :thumbsup:

i am already working on a big car 2 feet long, got from same shop, paid Rs 200/-,and motor is removed for rework, in the specs of EP 400,already rewound, and replaced brushes,but must work on this. i will finish this as i get mood..

Roopesh, I can see a classic book peeping out. It is by Bill Gunston. Which one is it?

you can see the quality of the gear wheels used in this car..all it are nice and well engineered.the RX contains 4 relays to cope with high current rating of the can type motor.ample of space to accommodate heavy battery pack and PWM, speed controller with reverse.

Good morning VC Sir..its the "FIGHTER", by Bill Gunston,from Parragon books.some of my collections..

Good morning! I have "Bomber", "Soviet Air Power" and a few more of the same publisher, Blandford and others. Fantastic Author.

oh my God..Sir, you have a nice valuable collection of books..happy..its all rare.. :hatsoff:

Sumi,increasing the supply voltage isnt an option to increase the performance of your car.instead you can go for a powerful motor,in to the same size,or can fix powerful motor to the same setup. how..? its simple.remove the motor. remove the armature.take a bicycle spoke, and cut it in to the size,longer than your real armature length.replace the driving gear on to the spoke. so, you will get a little long end at the opposite side of the motor. you can simply fix a gear or pulley to fix a powerful motor to your vehicle.you can use a BLD with ESC, only if you have a professional radio set. if not, can use can type motors, and can make ESC s your own with simple circuits. an ESC with MOSFET can take load up to 120 amps and 260 amps all within a size of a match box to a cigar box.its all reliable and proven.can operate with the same setup with your existing TX and RX.if so, you will get fwd,rev, left,right, and horn,if your Tx is based on RX 2B.

you can also add headlights, brake lights, reverse lights,direction indicators all according to your imagination.as modellers giving up is not our option..all we are RC Indians..think big..dream big..will succeed..

Good Said and nicely  said.

I am also working in the same kind of improvement, that that is sure we can only improve power (if we consider less money), but cannot improve reliability in low budget (like 4WD, break etc)
I am not so much electronics guy, so plz correct me.

I got this car @ 600 Rs and after few days I damanged its circuit so it stops turning left, then I tryed to replace its battry with Lipo battry and belive me it start drifting in floor,

and tonight I just order new Tx and RX 20$ and ESC 8$ and will let you result soon...

Friends see my postings..  http://www.rcindia.org/cars/high-performance-super-drift-car-from-toy-car/new/#top

and video..http://www.youtube.com/watch?v=k6REwGLKTt0

so please dont throw away your "cheap rc cars"..at lease you can give it to me.. :thumbsup:

Krishna,

Generally Rx circuits works in on-off mode and there is provision of turbo option in Tx2B chip.
(http://talkingelectronics.com/projects/27MHz%20Transmitters/imagesP2/TX-2Bcct.gif)

But in Cars, same battery is used for receiver as well as power. and receiver ckt may be.

(http://talkingelectronics.com/projects/27MHz%20Transmitters/imagesP2/RX-2Bcct.gif)

The main driving transistor replacing with BD139 and 140 set, you can easily increase the operating power of the driver.

But the transmitter works in switching mode. As you have not worked in Tx, then you must use, (reverse to forward and)speed up insted of forward and speed down ( with forward to reverse ) insted of reverse, like earlier.

But using that technic, stopping would not be problem ? Of course that can be achieved by using high frictional loss in gear assembly that increase/widen the stop zone , but that simultaniously reduce the power.

You can smartly use turbo with Vmotor = 50% duty cycle voltage and turbo will increase duty cycle. But you need an additional switch in Tx.

Thanks

Yes Kalyan..the manufactures of RX 2 the Silan electronics devices giving some options for conversion. but here our option is inexpensive and easy. so you can see in my video, instant motor starts and stops. in my experience BD 139 and 140 pair will hated up as the motor drops a high amps in drifting mode. so i prefer the MOSFET configuration. no headaches..works flawlessly.and nowadays MOSFETS costs less than a power transistor.so, inexpensive but excellent. and we can also wire our own Tx and Rx with handy components. so it will work greater than RX 2B. but it will take lots of time and efforts..

roopeshkrishna nice car and KALYANPRODHAN awsome electronics information, (but I am not enough Electronic Guy to understand, I wish I can !)

Anyways
as I said in early post, check my Toy RC Car with its parts only its battry (7.2V NiHM) changed with 11.2 8C LiPo battry.

http://www.youtube.com/watch?v=iHhQxG21n5s

But only right stearing is working,

Soon I will upgrade this with Servo, ESC and high range Tx Rx

Left stearing driving transistor in Rx burnt. Just replace after checking and reduce voltage in receiver and stearing movement portion.

i tryed but not so much electic guy, i buy same 3 leg transistor and replaced, but main thing I didnt get suspected transistor.

ok..you can check the number of the transistor, from it's front side, and can refer in to transistor data manual, or simply can search in Google for data sheet of the given number transistor.so you can under stand the transistor in to PNP or NPN. so can check it with multi meter, with probe, or easily can check with digital multi meter in transistor checking slot.the lead configuration of the transistor will be in data sheet as Emitter, Base, and Collector. so by simply inserting the transistor in to relevent slot, you can simply read the Hf E of the transistor, and determine the state of the transistor.you can also check the transistors from the PCB, while comparing the lead voltages. first of all make sure all prints are ok, means any burn outs. if so you can simply solder a piece of wire to reconnect the burned PCB. check all nearby components like resistor and capacitors. make sure the driving voltage from the lead of the ic is reaching at the base of the triggering transistor. if your craft is based on Rx2B, the lead no 6 will drive the right direction,and lead 7 will the Left. so you can measure the voltage in this points. it will be almost 1.4 volt to 3 volt in various input voltage. as you are going for a professional radio set, you can go for a BLDC and it's ESC, or can make your own ESC for existing set up.

Simple solution.

Take the car to a electronic friend or radio/TV technician. Also give him the receiver circuit. He will fix it easily. But if the Rx2 internally damaged, then you have to replace the IC.

Thanks

Hi roopeshkrishna,
I have copied your post in notepad, but I doubt I'll do it,
but yes this is good knowledge, I read that stuff initially when I damaged its circuit, and its long time back.

Hi Kalyan,
Let see, if any one is intrested, becoz its only 600Rs complete car so I dont think circuit cost will be more then 100 bucks. so let see if any electrical shop will repair it or not.

Finally Today I have received Hobbyking HK-300 complete remote controll, it built quility is good, this is my first 3-CH Tx Rx for Car.
anyways I bought because I wll buy some starting range RC Car, most probably Turnigy 1/18 at HK. then I will use this remote there.

but Unfortunatly I ordered ESC without reverse function

after few Hrs I will upload its pic

So Tx, Rx, ESC and Servo are already in Place just charging my LiPo Battry.

Hai gbisht ..please post some photograpps of the Tx and Rx..? how is the final cost..? please. :thumbsup:

Friends, all you can buy such toy cars within a 200/- Rs, and can also collect ample from whole sale dealers, duty paid shops, as damaged. most of the damages may be within battery box, or loose or broken contacts,or may be by power switches. by last week i got 9 more RC toys from my friend. most of them are affected with minor issues..now working on it along with my project works..rewinding motors.

Hi Roopesh,

I ordered HK-300 Tx Rx, 1 Servo and 1 ESC and its cost me around 2500Rs. I know it is waste for RC toy car  :banghead:, but I ordered because I will order soon, a real Electric RC car without Tx Rx and use it there.
start with cheapest (Turnegy 1/18 @ HK)

That is car I was purchased at 600 (long time back)
So Finally posting ESC, Servo and Rx installed Pics & Videos  :)

Sorry Dont have enough space in Drawing Room  ;) So Hitting almost everything in Drawing Room (Driving skills is also bad)
