As can be seen from the demo above the cars can travel quite a bit of distance
for small antennas. If I wanted to increase the distance, making the antennas
longer and supplying the transmitter with 12V would do the trick.
The reason why the cars sometimes veer to 1 side is due to the cart wheel at the
front. An ideal substitute to the cart wheel would be ball casters, however
since I didn't have any at the time and the cart wheels came with the kit, I
decided to stick with them.
It is also noticeable how many times I over steer the cars, this is
due to a lack of speed of control. Since I am not using a joy stick
or an analog / pressure sensitive keyboard, I am not able to control
the speed therefore the car goes full speed in 1 way or the other at
the push of a button, I may fix this my implementing a joystick
controller of some sort.
