Ok. Sorry for me not being precise.
here are the specs.
The remote control consisits of IC and a coulple of transistors,some resitors and capacitors. The IC is TX-2B Y5AF8. The circuit of the car has some transistors,some resistors some capacitors and three ICS- 1.( RX-2B Y4L97) 2.(L9120 LXE02) 3.(L9110H LXD43). The present power supply to the car is of 1.5X6V=9V. I want to increase the power supply as well as increse the range of the Remote control. Please help me with it.
