There could be many different problems here:

• Your transmitter may have disconnected wires or a blown circuit board
• The car itself may have disconnected/loose wires or a blown circuit
• The electric engine may be blown

If you have good soldering skills you may be able to reconnect wires, or install a new circuit or engine for cheap. Otherwise you can take it to a shop to get it fixed up, although it may be cheaper just to buy a new one. I hope this helps

Check the Transmitter Antenna and battery. low battery means short range and the antenna could be broken. Have it checked by a radio modeller shop, but first replace new batteries and inspect the antenna. I don't know what brand it is, so I don't know what antenna you have, an extendable antenna or a short stub.

overloading the speed controller, is there grass or hair wrapped around the prop shaft? could be a faulty controller or it could be a range thing as they go into fail safe when they lose signal

How old is battery? How long has battery set without being charged. When they dont charge proble is a depleated cell or battery. Take it to a hobby shop or some one with a tester.

They are available on line from several places . http://www.hobbypartz.com/cars.html
