Micro RC Car Teardown

Featured
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...

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.

i don't understand what your doing

"Flashing Light" is just copy and paste, like the "try me function" in my pic
I literally have what is shown in these pictures on my desk in front of me right now.

Thanks for verifing the parts, My Step Dad was a TV & Radio repairman in the 60's, but thats about It, cOOl. G-G

I just had a vision of a tiny tank robot with those two motors and batteries.

what would you recomend using the stuff for?

Thanks for posting this! It was helpful in aiding me in taking apart one of these without destroying it. I used the receiver in a remote controlled firework igntier and it was a huge success! I'm making an instructable on that soon, and I was wondering if it would be alright to put a link on my instructable that would lead to yours? It's to show the viewers what R/C device I used and how to disassemble it to get the receiver out.
Hey, I have this same RC....I am ready to take mine apart... Any Ideas on what i could use the engine, wheels, and batteries with?? Awesome pics!! plz reply
Make a plane using them. That's what I did once. Lasted a week though (paper doesn't crash well, but looks awesome doing it.)
paper can be set on fire too :-P
I know.  One of my friends lights paper planes on fire and throws them.
he throws them into pools right?
Wherever he wants, actually.  They land in pools, knock over drinks, land on glass tables, sail into other yards.  But, he usually follows them up with a bucket of water if they land somewhere where they can cause harm.  One managed to get away and landed in the river, though.
haha
If you have the Vulcan,(nerf gun) or any other battery powered gun you can hook the motor up so it spins the gun left and right.Hook up the other motors wires to the trigger. And there, you have a radio-controlled weapon of mass destruction.
a bit heavy fr these tiny motors dont'cha think?
maybe... but i meant you just use the RF receiver module from the car and use some really nice, really powerful gear motors or servos.

i just got this very car to cannibalize for parts and its great! enough motors to keep me going for a long time.
you're a plastic car?
Colonel884 years ago
great i think ill go hook up a couple of those motors up to make a new custom car (?). Or I could just hook-up the servos to a radio controlled nerf gun, *evil laugh*

are the motors the size of pager motors
westfw (author)  zaktanandy5 years ago
Yes. Larger pager motors. but still tiny. 3/8 inch diameter, I think?

its so cool i dont know how to make it i dont have any materials can you make it very easy simple materials
westfw (author)  adave123xx5 years ago
This "instructable" is about how to take it apart (and what's inside), not how to "make" one...
adave123xx5 years ago
what kind of motor?
adave123xx5 years ago
what kind of battery are those too..
adave123xx5 years ago
what kind of antenna?are those?
adave123xx5 years ago
can you?then show me please thank you very much god Bless

I always assumed these micro-RC cars were powered by a small capacitor bank...
thats would make them expensive
Would probably run longer, too...
if it had super capacitors, then yes

How about mini plane/glider? the chip and motors dont even weigh 100 grams... with big light wings... could it happen?
when I was like 8 i ripped one of these apart in hopes of creating a micro rc boat after 5 minuets I got confused
You've got to write down -everything- as you take it apart.
i love polymorph! anyways i disassembled one of these but the wires came off the motors, so i advise everyone that does this to like glue 'em with a hot glue gun so they wont snap so easily, they are very thin...

this was actually a very good car. if you had a lite touch you could lift one of the fount wheels to do a tight turn.
