Another R/C Car Hack

Another interesting instructable about taking advantage of the 3rd channel built into most R/C cars (for turbo button) chips to add in your own custom item.  In this case toy guns.  Of course the author thinks its a 5th channel, but if memory serves correctly, its a 3rd, first 2 are for forward/backward, and left/right.  Read all about it here: http://www.instructables.com/id/Hack-an-RC-cars-unused-5th-channel/
