rc car building

I am interested in building an R/C car for the first time but i don't want just a standard bought kit i was more interested in buying all the parts individually can any one suggest where i start and what parts will be needed do i start with the motor or the chassis i really don't have any idea. So if anyone can give me some serious direction and helpful information on how to start and possible parts that would be great. Also could i just purchase an instruction manual for a kit and buy the parts individually instead of the kit and upgrade certain parts. thanks very much and no clever comments about how to use google my self i have tried but it just keeps sending me to self build kits and this forum site with other questions about self build kits thanks again

Guide to RC? Answered

So don't tell me to go and buy a small RC car, and hack it. I want to know how to MAKE one! Like, totally MAKE! Where can I find out where to make a simple 2-4 channel RC thingermabob with a range of about 50 feet? I just don't get it, everywhere I look, they make these huge units. My helicopter is 6 channels and the circuit board is no bigger than 2x2, and only has 2 IC's on it. Why can't I find instructions for some small and simple like the circuits you find in RC car! What about Zip Zaps! Their circuit boards are tiny, and work better then the huge circuits you find online! Thx!

rc project

I decided to go for the rc car. I'm using the 1/5 scale  maxstone trying to combine it with the raspberry pi. I'm also using adafruit's pwm. I know this might be old to others but it is new to me. I am a beginner and I am very excited about it!    I am open to any suggestions, comments, feedback, links, anything would be great!

RC car ¨tuning¨

So I have an RC car and so does my friend and whenever we race them he always wins so I was thinking of maybe tuning it a bit (you know add an extra battery or something) so how can I tell how much voltage my circuit board and motor can take. The car itself uses a 12v battery and is fully digital (you can go slowly or quickly and you can turn only a bit or all the way, you know what i mean) I can provide some photos of the circuit board if that helps, just ask.I know that RC cars are a bit childish but when Im older I want a job involving cars so thats a good place to get started =]

rc car no longer accelerating?

Alright, so ive got this rc car, it runs off of a 7.2v battery pack and has variable speed and turning. it is not a hobby-grade car, but it is still something id like to hold onto. today, when i tried to drive it, i discovered it could not accelerate, forwards or reverse. it can steer fine, but trying to accelerate does nothing. ive ruled out the controller and the motor, which means the h-bridge and associated circuitry must be to blame. i tested the battery in another car of the same model (not mine), and all was well there. the h-bridge must be PWM controlled in order for there to be variable speed, so heres what im figuring: the motor is making a clicking noise when i pull the trigger on the remote, looking at the motor, it is turning very little and then stopping and then doing this again, at a fast rate. when it stops turning for that split seond it returns to the original position, because it has turned so little. i know the motor itself is fine, because i connected the battery straight to it and it spun up and turned the wheels. i have a feeling the issue lies within the PWM control. i cannot guarantee the receiver chip is fine but it seems kind of odd that it would be the part to fail; regardless i cannot find a datasheet using the numbers on the chip. if i were to try and look for an issue/failed part somewhere, where might you guys think i should start? there are a number of transistors on the board around the h-bridge, some capacitors, and a lot of resistors as well. i checked all the resistors inside the h-bridge and they are all the same value as the bands indicate, andthere are no corroded or cold solder joints. i plan to test the h-bridge on its own once i find a diagram i can reference to, that way if the h-bridge works i can rule it out and narrow the possibilities. if you need any more information please let me know.

Coding a traxxas rc car?

Hello everyone I have a Traxxas funny car that I am trying to code using an Arduino with a motor shield. the motor has a brushless DC motor that is hooked up to a ESC then has a output the same type as a servo motor. and the front steering is a servo motor as well. I have a competition where I need to drive the car a certain distance then turn it between a set of cans and have it go back to the center line and land on a dot on the floor. Every time the distance is different and I need it to go to the dot at the fastest time possible. Right now I have the brushless motor set to input 2 and the steering is set to input 1. If anyone could help me write a code for that it would be greatly appreciated Thanks a lot.

Rc car modding help?

My dad had (broken) a rc car from a old friend that was sitting in the garage. He said that I could have it. It is a Nikko Super Dictator. When we were trying to fix it the curcuit board went poof and clouds of smoke came out of it, I don't want to fix the board but was thinking about buying a cheap RC kit and using arduino to decode and to control it. Another way I thought of controlinng it was to get an rc kit and use a speed controler. The servo in it has 6 wires and has no markings on it to tell me what it is. If anyone has done this project before please send me a link to an instructable. Also Please tell me the easyst way to control it and if I could just use a prebuilt rc kit with a speed controler, the type of servo and the motor. IF ANYONE HAS ONE THEY WOULD LIKE TO SELL THAT WOULD BE GREAT TOO, JUST SEND ME A MESSAGE. Any help, tips and/or links would be appresated. PS: Do a google search to find out stats. thanks, David.

RC Noob

I've never done much work with RC control, and i want to build a little rc car with tank steering (2 motors, one on a wheel on each side so steering can be accomplished by which motor is on).  I know I need a transmitter and a reciever (I dont know specifics of each :P).  All I know is that i want to PWM the motors and control with 2 home made H-bridges (motors require max current of 30 amps, so commercially made ESR's are too expensive) and control it via rc. I just really dont know what im looking for in the rc world.

Remote Control Car Controlled By Computer

I'm doing a project where I am rewiring a remote control car remote to work using a computer interface. I've found a few tutorials on how to do it, but they all deal with a "button" controller, where the motion is controlled by pressing buttons rather than using a "pistol grip" controller, or one with a wheel to control turning and a trigger to control acceleration and deceleration. Has anyone tried this, or does any one know if I would be able to use the tutorial linked below with this controller. I highly doubt it would work, but I would like a better opinion.http://jbprojects.net/projects/rc/
