How to swap Bit/ZZ/Clone/OEM receiver PCBs.

It has come to my attention that ZZ owners as well as others want to swap out their receiver PCB. This opens the door for many frequencies that were once forbidden (damn FCC)! Here’s what your gonna need.


1) ZipZaps or a suitable test subject. (great running car w/dead board?)
2) “Clone”, “OEM” or “Bullet” car in any of the different frequencies. That will give it’s life for this wonderful experiment. (you should test run the donor car,, because sometimes you can get a really great car)
3) Correct tools (good soldering iron with fine tips, project holder thingy with alligator clips, some basic soldering technique)



Prepare the patients.

1) Strip off the body and PCB cover for both cars.
2) One at a time de-solder the wires off the PCB of one car, then do the exact same thing on the wire from the other car’s PCB. You can disregard the color of the wire. If you look really carefully (even underneath) you will notice that there are little letters next to each of the solder points. They should match up except for the “F” (forward) and “B” (back), these two wires need to be reversed (usually).
3) Don’t mix up the hair-thin, incredibly fragile, extremely easy to break steering wires. These will go to the L (left) and R (right). (If you put it together and your steering is reversed, but otherwise working… I would just flip the magnet and glue it back in.)
