Setting up a remote control car is as much a science as it is an art, the physics behind rc cars is exactly the same as the physics that governs real cars, if you know how setup changes in a race car work, you already know how to setup a remote control car.
The problem that most people have with setting up RC cars is that when you make a change in one area it always has a knock-on effect on the rest of your settings, setups are very much a balancing act
To start with I’ll concentrate on the basics of handling, over steer and under steer. The physics behind this is pretty simple, if you turn into a corner the center of gravity will move in what ever direction you were initially travelling. Your tires via friction push back with (hopefully) an equal amount of force. When your wheels lose traction and start to slide the energy that was being turned into heat in your tires gets released as inertial energy in the original direction of travel. With cars, both back and front don’t break traction equally, this creates either under steer or over steer, which is how we describe the experience the driver has under these conditions.
Under steer
Under steer is when the front of the car loses traction while the rear of the car still has grip on the tar, the effect is that the nose of the car drifts away from the direction you are turning, turning harder makes it worse, the only thing you can really do is back off the throttle and bleed off speed.
Over Steer
Over steer is the opposite of under steer, and in most cases it’s best to have a little of this. The front of the car keeps traction while the rear lets go. One of the key benefits is that you can typically corner much faster in a car that has some over steer
Over steer / Under steer Tuning tips
There are a lot of ways to tune the handling or your radio controlled car, the easiest is to adjust the front and rear shocks. While there are a lot of options with springs, different oils and all sorts we are just going to concentrate on the basics, most decent shocks have adjustments, either with spacers or bolts that let you adjust how hard or soft the shocks are.
As far as maximum and minimum stiffness goes, make sure that the bottom of your car doesn’t scrape the ground, and on the other end make sure it doesn’t bounce and leave the asphalt, apart from that you need to find the setup that matches your driving style, most people get winning setups off the internet and try to learn to drive them, mind you this is a great starting point, and most championship winners post their setup sheets
Shock Stiffness guide
Stiffen in front = increasing under steer or reducing over steer
Stiffen in rear = increasing over steer or reducing under steer
You may be wondering why one setting makes two changes, this is because it’s all about balance, you could for example setup your rc car by only every changing the rear stiffness, but you would find that when you got the perfect amount of over steer under braking the car would then be uncontrollable during the exit of the corner. It’s all about balance,
Another thing to keep in mind is that when you change the shocks you also change the roll of the car, this the the chassis of the car moving with the inertia, in effect pushing the front tires into the road during breaking and the rear during acceleration. If your shocks are too soft then the transfer might dig your front wheels in and lift the rear enough to make you car spin out, or lose steering under throttle, you have to find the right balance

Instructions on building a remote control car?I have looked everywhere and all I got were kits. Please give me instructions on how to build a remote control car and give me list of what I need.
Please and thank you

fake at the end,u can c it because everything else speeds up as well.Including the 200mph birds in the background
wow, the bird in the backround must be going M-10. CHEESE!!!!!!!!!!!!!
oh my fucking god its smokeing
Unless you are "allowed" to build your own RC remote/receiver, hacking an existing RC remote will be a pain in the butt. Of course if you are allowed to build from the ground up, you have tons of options.
Oooook. Short answer, is you can't. Long answer is; Each remote car, and remote car radio handset has a crystal in it. The crystal in the remote car, and the handset it came with are identical, producing the same frequency and running your car. However, the cheap remote car radio handset your purchased has a very slightly different crystal, it is still 49mhz, but it may be 49.174 while the one you had before was 49.566. Basically this means that you wont be able to get control of the car with a different handset. However, hobby grade cars have the crystals visibly on the outside of the radio handset. IF this is the case, you can remove the crystal from the handset, and switch it with another. Same with the car, IF ITS HOBBYGRADE you can take the top of, the crystal will be poking out of a small black box, the reciever. IF this is the case, you can swap the crystals around. However if what you've got is two toys cars, im sorry to say it, your stuffed. If you need more info, see http://en.wikipedia.org/wiki/Remote_control_car#Toy-grade_radio_control
that was light speed or i have bad seeing
first if it has a a starter than put batteries in it
then put the nitro in the vehicle
then try starting it with the starter
(if problem persistce than wiggle the exauhst pipe until exauhst is moving out freely)
if this still does not help than im sorry i cant help
you can see the wings on the “flies” around 0:56 the light under the flag starts to blink really fast too, but who knows.
Get a life!! This has to be the worst hobby anyone can think of. Why don’t you get someone to jump-rope as the car (thing) goes round. That wuld be entertaining to watch somebody jump like a GD fool!
Go to a prof. hobbies shop, if they don't have the whole kit they should have the control transmitter and receivers you need.
i would be scared to be the guy that starts it up
With a very good sense of imagination..
200 MPH eh? Goes well with the 200 MPH birds flying in the background.
If it was just an electric toy car, you would increase the voltage the motor is getting and it would go faster. But being remote control, it has some electronics in it that could be damaged by higher voltage.
But there is always a way. Do you know much about electronics? You need to wire in a relay between the motor and the control box. You wire it so that the control box doesn't send power to the motor any more, it just sends a little power to the relay to "trip" it (a relay is just a switch that it turned on by electricity – you can get one at Radio Shack).
Say your car runs on 6 volts. You would hook up some batteries with say, 12 volts, and connect one of the wires to the relay, the other wire to the motor, and then run a wire from the relay to the other motor wire. Now, when you press the button on the remote to make it go, the controller in the car will turn on the relay. The relay will connect the 12-volt power to the motor, and off it goes, twice as fast as before.
You might even consider running it at 18 volts. To do this, get 4 or 6 rechargeable 9-volt batteries. Connect them in series pairs – two batteries to make 18 volts, then two more in series, with this series connected in parallel to the first. The more batteries you have in series, the faster it will go. The more you have in parallel, the longer it will run.
Hope this helps!

Try BestBuy or Radio Shack (if they even still sell things like that).
