How to convert (almost) any 27 or 49 MHz RC Car into a Robotic car

Step 2 A closer look at a hacked board

Here you can see chip was removed and that wires were installed instead 

Note - some boards do not use a variant of the TC RX2C  chip instead they will have a daughter board (the last picture in the set)
Also some boards do not use transistors for the H-Bridge but rather use micro relays.

Interfacing to through hole dips is easier than soldering carefully to surface mount pads. Also care must be taken not to strip the pads by pulling and wires should be secured to board using hot glue or by some other means.
