I already did a RC car using Arduino and it worked pretty well, but I think it needs something more.Things I used
I used two NRF24L01+ modules to make the comunications between the car and the remote control. It has a impressed antenna on it's PCB and can reach a distance of 100 meters.
I used a 4wd car chassis kit like that one:

For the remote control I used Arduino Uno and a Joystick shield.
The joystick shield (Funduino V1.A)
To control the car I'm using Arduino Nano and a L298n H-Bridge. To power everything, I'm using 18650 batteries like that one:
After a moment of thinking, I decided to make a laser turret for the car using two servo motors, controlled remotely.
This is how the car looks like after the assembling:
This is how the control looks like:
