one help guys can i connect a 2.4ghz reciever to a cheap(200-500rs) rc car without esc??

u can make ur own brushed esc for that

No, you can't connect it directly. You'll need a brushed ESC. You can purchase one (easier but costlier) from a LHS. You could also easily build one if you are familiar with electronics and microcontrollers. I could give you circuit details if you want.

OK can u pls give me the circuit? and also how much money does a simple 2.4ghz rc car remote set cost?

Nothing less than Rs 1500 for a HK 2.4G Trnasmitter, that too with a big risk of the radio getting stuck in customs.

try rcbazaar.com , they sell the cheapest radio, cheapest only in price.

Yup, RcBazaar is the one with the lowest prices on Radios right now. Check it out here:

For the circuit, I need to know if you have any experience with micro-controllers (if yes, which one), so that I can give you appropriate details.

huh? ...
Oh, I think you meant to post in 'Highest Speed u'v done with your real car...!!!!', right?
