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.

Hi everyone  Does anyone know how to make a electric wheelchair in to a rc wheelchair?

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!

     Hello everybody i am building a 34 inch wingspan cessna 107b n2789d plane and i am looking for some advise urls of free plans and i am looking to make it out of blue core dow fome so any advise on servos, batteries, motors, esc, props pleas let me know. Thanks, Cobalt420

Looking for rcplane plans

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!

I am starting to design the rc airplane I will build for my senior project. I need help on wing loading and how wide I should make the wing (not wingspan) here's what I have so far: 1. at least a five foot wingspan 2. Twin engine (electric) 3. The estimated weight of the electronics is two kilograms. 4. The estimated weight of the fiberglass for the whole plane should be around four kilograms. 5. Plane will have twin rudders as well and most likely be a belly landed. I also need help on props, engine power, and wing diameter. if I need to specify anything please ask. many thanks    Zach

I was wondering if it would be posible to take an rc car motor and the chip and replace the knex one with the rc

Hi i have decided to make a rc boat i have the motor all sorted out its just the body. I was hoping to make one from styrofoam or polystyrene dose any one have some tips. Will this be water safe in other word's no water seaping througth . Thanks

Something along these lines...

The motor for my rc airplane won't move. It's just not turning on. The airplane is the hobby zone super cub  part number HBZ7100. I've checked the output for the motor and it's reading full voltage ( I'm assuming 9v is full) and I've even changed the motor. Please help as I need an airplane to fly while I'm making my new one.  Thanks, bud P.S. I will specify anything, just ask

There are lots of rc cars out there, with wifi linking capabilities, but I was wondering whether you could be in one house connected to wifi, and controlling a chassis/rc car in another house without using Arduino.  (I'm really bad at electronics).  The reason being, I want to build a Mobile Virtual Presence Device with a fairly large stable chassis that can be controlled from somewhere else.  If you can name a way to do this, I would appreciate it. Thanks! -Finzaz

Hey guys, I am not much of a knex guy, but I made a strong trailer for my RC truck to pull around at the campsite to collect firewood (just sticks haha) anyway I made a knex "adaptor" for the car, but I cant figure out a way to make a strong connection between the car and the trailer.  Can someone help me out???

Ok so I am constructing a scratch airplane as some of you may have read on m other questions. I have reached another dilemma, whether or not a moving rudder is completely crucial. I'm thinking i could get away with just having a stabalizer fin in place of the rudder.  Any help from you pros? Thanks, Bud

Both RC helicopters and DSLRs have shown some amazing advances and when they're combined the results are amazing. Eric Austin has a company called Heli Video that specializes in this with a helicopter-mounted Canon 7D and the footage rocks. With a free-roaming helicopter he can get shots that swoop in and out and then look down from above without any need for a crane or anything else. There are also no mistakes allowed as a crash means several thousand dollars worth of gear get wrecked. Check out the first video to see what this technique can do and the second for a view of the helicopter at work. via Core77

Hey guys I was wondering if anyone of you could help me select which project I should make (my first RC plane) Here are the requirements:- 1. Must be easy. 2. Its body should be DIY and made of wood 3. It should be under $100 4. The instructions should be really clear Sorry I didnt have time to make a well written question neither did I have time to correct my grammar 

Just a bit of background, as a bit of fun and a learning (LOTS of learning) exercise, I'd like to make myself an RC tank, ie: http://woodgears.ca/tracked_vehicle/index.html I've aimed pretty high with this one though, as I've no experience with Remote Control applications, though I'm fairly comfortable with electronics. I was hoping for an overview of what I will require (transmitter, receiver, servos, etc) and good places to look for these components, so I can move on to actually planning. Thanks in advance.

Hey, I just got a new RC truck that is moddible in like 100 ways. tell me what to do with it besides bigger battery and giant wheels.

I've been working on this sucker, and I have so far added a battery pack to it that consists of 8X AA NiMh rechargeables and it goes like sh*t on a stick! 13v when it's fully charged! Check it out! Wheel cam:

I have a bit of a dilemma with an old rc boat that I'm retrofitting with the board from a cheap rc car that I bought at walmart. The boat is meant to run on two 9.6 volt motors, but the radio board is designed to only handle 6 volts. Is there anyway to utilize the motor leads from the board to trigger some sort of circuit that would allow the board to use it's original 6 volt power pack while supplying the motors with 9.6 volts from a separate battery?

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

I have been thinking about building an R/C airplane. Here are the specifications I need. L:3ft W:4ft H:6in ( 15 with prop and landing gear Engine: Chain saw motor Prop: 12in Control surfaces: 2 ailerons, elevator I don't know anything about R/C and here are my questions: 1.) How do you assemble an R/C system? 2.) What is needed to run 4 servos(3 control, 1 throttle)? 3.) Where should I buy stuff? 4.) What else should I know? I know how to connect servos to an air frame and everything, but I need to know how to connect a full R/C system together( receiver, servos, battery, etc.). Any help? Please. P.S. My air frame will be, a wing, a wooden dowel going to tail, tail, motor and muffler. I used this design because I have no weight added other than required materials.

So I posted this as a question a day ago, but I thought I might get a better discussion going here. The simplified version is that a friend and I are looking at designing a tiltrotor UAV or RC vehicle. As we are college students we don't have the disposable income that some people do, so we'll probably stick to a small RC vehicle just for the hell of it. Anyway, some ideas we've had for the project: Hardware: Folding for storage (see this link for reference: http://sportscarforums.com/gallery/data/748/v22_folded.jpg ) Coaxial rotor blades (unsure if this will have any affect during STOL but should help with VTOL Ducted Fan (a standard ducted tail rotor to provide the torque to keep the craft from rotating with the blades) Separate Batteries (dedicated batteries per each rotor, failing that, one large one for all systems) Amphibious Software: Auto-Hover (depending on the approach, I may be able to write a script to maintain a certain motor power level) Auto-Pilot (just basic stuff, like flying patterns and such, perhaps make it able to land itself when in VTOL) Additional: (totally unnecessary but cool nonetheless) Micro-Camera Laser-Directional Microphone Laser Range Finder So anyone have any suggestions? We were hoping to make this a reasonable size, as in the length of the fuselage being anywhere around 3 ft

Didnt know which section to post this in so correct me if ive posted in the wrong ones! Ever since i started in RC a few years ago ive had a passion to help people so ive started a rc channel and would be grateful if you guys/gals could check it out! http://www.youtube.com/user/mrfishin101?feature=mhum Rc world! Im hoping to put videos up daily!

Id just thought id let you friendly bunch know of a new channel ive just creaated for anything rc related. http://www.youtube.com/user/mrfishin101?feature=mhum Feedback welcome! Thanks :) Sharlston

This sunday i will show everone how to make a rc plane from oround the house things. the things u will need is  1 motor 1 hanger 2 servos 1 shoe box so im am tellin you this so u will get ready to make it.                        if u are exicited about this please comment on it.

Hello everyone!    I'm trying to start a project with and Rc Truck from top to bottom. I would love to have help on some cool Ideals that I know you all have! Maybe like the Suspension, Lights, body frame, color, etc anything you think that will help OUR ride look awesome!  I'm looking to spend anywhere to  1000 dollars with this project! If you have any ideals even the smallest thing please notify me! Thanks!!!

Hello guys i recently got an old helicopter with two good motors and a good frame with a control board i was wondering if some one can help me to interface with on board circuit to controll it with arduino. What i'm traying to say is to use the arduino as transmiter to send signals to the helicopter so i can control it.

I know that rc cars are not allowed to operate on rc planes frequencies, but what about vice versa?

Burn capacitor on my motor and i can't read the code or number on it. what will be the best capacitor to buy or to put on it?

Hi i have a 1.2v rc car batery and my car ran out of power early a then usal.So I got my voltage metre and it said the car still had 7.2v does any one know why this might be thanks.

Okay, so today at school, we learned about Bernoulli's principle and how wings help a plane fly. So I was wondering, if you built some good wings, attached them to an RC Car, and drove it off a ramp, would it glide for a little bit?

I'm not sure if I post this in the right topic, so let me know if I didn't, thanks.  My kid got two rc cars a couple of xmases ago.  One of the RC controllers antenna  broke off and want to know if there is a way to make a universal rc control unit so my kid can use one controller for both cars?  Kinda  like a similar function you have for a universal remote for a tv.  Thanks for any help you can provide.

I recently took apart a RC Jet Ski. Within the Jet ski there was a servo for the rudder. I Need to know what wire leading up to the RC servo motor do? (green and brown). If I were to take the wires and use them on something else what shall I control them with? My first thoughts were that sending an electrical current though the postive, would make it turn one way, and by the RC control, electrical currents could be past though postive and negative to make it turn left and right. I know what all of the other wires. Thanks Oscar 

I was wondering if anybody could help me make an RC knex car this is what i have i have 100 to 150 knex, one 49mhz RC controller and reviver i also have some RC car tires. P.S. the car reviver is from a New Bright RC car.Also i have no cyber knex motors i have a good amount of reagular knex motors most are the green ones also have a good amount of wire.

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 =]

So i bought a rc heli from a thrift store and it turns on when the switch is flicked, but it came without the transmitter/controller for it, i checked the hobby shops and they said that they don't have any spares for it it says on a sticker that the heli is a 27MHz, so i was wondering, if i got a transmitter that was designed for helis and ran on the same frequency, in theory it'd work, right? can anyone lend me some advice?

Hi my names Paul Im doing a project on building a Mind Control RC Car using the EEG Emotiv Headset. I was planning connect the headset to the laptop and use an arduino to connect up to an interface board(im not too sure) which connects to the remote joystick.  I was wondering if anyone has done this project before and it would be so awesome to get any tips or instructions of any sort.  Thanks please let me know

Hello instructables users. I'm wondering if anyone has ideas of how to make a revolving bottle rocket launcher with an igniter. this will be going on an rc car. any ideas will help. Things I'd like to see in your idea -hopper -igniter that will turn on/off simply -place for bottle rockets to launch from Thanks for the help

I took apart a RC helicopter and stripped everything so its just the motor operated by remote. I plan on attaching a camera to the end if the motor and my goal is to make a pan/rotate base mount thing. However even on the slowest speed (lowest on the throttle) the motor spins way to fast. Is there anyway to control the speed or slow it down? Please Help

Http://tronixstuff.files.wordpress.com/2010/06/pic23.jpg Could someone please explain how this circuit works? I understand that while the capacitor is charging, current flows to the base of transistor and so the LED lights, but I can't figure out the discharging. P.S. I assume that by building this circuit I'll get an LED blinking constantly?

I was interested in a wireless spy car to use in my backyard (to hunt for a waskaley groundhog : elmer fudd) now i was looking in Make mag and i found this( http://makezine.com/14/bajabuggy ). it really dosent tell u how. now i already have a rc car (Traxxas vxl Bandit) and i dont wont to destroy it or buy a new car it cost $300. so i wont to know how i can still use a servo without connecting it to to bandit wiring and for cheap

I would like to build my own rc airplane. I already know how to build the fuselage and the wings. I also have the landing gear. I have a 27mhz rc circuit from an old rc car. The problem is the car was only a 2ch board. I need a 3ch transmitter and receiver. (Throttle, left/right, up/down). I'll be honest, I don't know much about circuit boards, but I can learn. Does anyone know how to make the circuit board for this, or where I can get a custom board made for me?

Ok, so before I actually get to my question let me explain what I am doing. I have a traxxas rustler, I wan't to put 4 wheel steering on it, and I wan't it to be very stable.  I know how I am going to set up the steering, but I need help with the electronics of it.  The stock reciever has a channel 1 output (to ESC) two channel 2's (for two servos) a channel three, and a channel 4.  I wan't this car to be able to switch one of the servo's from inverted to not inverted using channel three which is the output of a two position switch.  Is there a way to do this without mechanically connecting the whole fancy layout seen below?

Hi everyone. I have used epoxy to waterproof my RC receivers. I have thought that there is no need to waterproof the connections because it is only 6V and not enough to corrode the connectors. I still want to be able to swap my receivers between models. I have splashed through puddles before but not completely submersed it in water. So is there any reason that I should be waterproofing these connectors? Or is the voltage not enough to cause any problems? Thanks, David.

If been wanting to film some of my Rc flights iv been thinking of two ways to do this: A.) buy a mini camera (not wireless could cause interference with other planes or mine although it should only affect 2.4GHZ or spreed spectrum channels which are designed to handle this kind of interference but i dont want to cause any accidents) or B.) Buy a cheep digital camera and mount it to plane Things to consider:Any thing will add weight to the plane which will affect balance (to solve this add weight till balance)I want to avoid wireless. How to power; battery's weight a lot and take up lots of spaceDragSize of cameraIf i do use micro camera where will it record too?Dose any one have any suggestions or ideas on the best way to do this on the cheep?Original form (it was origanaly posted in that group but it got separated) *update* i found a Camera called the flip video camera it has every thing iv been looking for its cheep about 150$, has a tripod mount, records 60 min of video, comes with editing software, runs on 2 AA batteries, and has a small (1.5inch) Lcd screen

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.
