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.



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.

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  , 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)

Electric Parts Installation



Little Drift and Break



Trying to Drift

BRAVO...well done..

Thanks Roopesh,

I am planing to purchase HK another Rx for this Tx and will use it in my new Starting level RC Car, and my total cost in this car is
HobbyKing 939MG Metal Gear Servo 2.5kg/ 12.5  4.37$
HK-3000 3ch 2.4ghz FHSS RX suit the HK310 Transmitter  8$
Turnigy 30A BRUSHED ESC     7.44$
+Shipping

aprox 1200Rs excluding Tx, because I have ordered solely for different RC Car

woow..cool..
