I bought a full function radio controlled toy car 27/49MHZ and it does not work. I've put all new batteries in it and it still does nothing. Can you help me with this problem
I don't understand the 27/49 MHz reference.
Most radio control is 27 MHz.
Licence-free personal communication is 49MHz and in the real world the two frequencies are oceans apart.
Dual frequency band might be a good idea for a full function toy car but usually, considering a manufacturer doesn't often make something better than it needs to be, a radio control tends to be either one thing or the other and not both.
If the cars are available as either 27 or 49 MHz, don't ignore the possibility you might have a radio control that doesn't match the car.
Such toys are rarely built to anything but a mediocre or low quality and faulty goods are far from unknown. It would be wise to know something about what you have and how it works and reading the instructions thoroughly would be a good start.
Don't assume the batteries are all good and test them before fitting them. Ensure the batteries are fitted the right way around first time - the wrong way around could cause terminal damage to the electronics even if only for a few seconds.
