This is sort of an "example" instructable for the Dr Destruct-O Teardowns group; something I did a few years ago. I don't know if this particular car is still available, but...
This is one of those mini remote controller cars that was all over, selling for $10 or less. It wasn't so great as a car; the "stunt" capability is derived from spinning the front set of wheels on a axis that runs down the centerline of the car, so you can't really steer it; you can just make it go forward, back, and tumble around. But the two channel Radio control might be reusable, and perhaps there are some tiny gear motors that might be extractable...
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Under the Cover
I recall this being pretty easy to take apart. The body of the car comes off in an obvious way (small philips head screws?) This is what it looks like under the body, before further disassembly.
Step 2: Electronics
The radio control receiver is on a nice tiny board that is surprisingly well labeled. Since there are two motors to control in this car, there are two fully-reversible motor drivers. On the minus side, the board uses "chip on board" (the main "smarts" are a a bare chip under that black plastic blob), so some of the modifications possible on receivers with identifiable chips and pins aren't possible here.)
(It would be nice to have pictures of the transmitter as well. Sorry...)
Step 3: Naked Electric Car Guts
Here are the "internals" completely separated from the chassis of the car.
Note that the motors detach complete with their respective gearboxes, and have convenient places to attach devices other than the original wheels. This is EXTREMELY valuable; all too many toys have their gears mounted directly on the chassis, and by the time they are apart you have a motor and some loose gears. With the stunt car, you wind up with TWO gear-box motors, which are regularly worth about 10x the price of a bare motor on the surplus market.
Step 4: Motors and Batteries
Here are closeups of the motors and the batteries.
The batteries are labeled as being "80 mA" (which isn't really a valid thing to say.) They probably mean 80mAH, which makes these NiMH cells. They're 1/3AAA size; which was pretty popular back before the serious RC crowd converted to LiPO.
The motors and batteries in this car are easily worth the $10 price tag on the car, even if you can't utilize the remote control...
