ive been dying to make an rc helicoptor...theres this cheap $10 aus rc car would it work to make a chasi and put the insides of the car into it? heres the link to the car
http://www.wowwicked.com.au/catalogue.php?p=22 would this work?

helicopters are pretty hard to make from scratch $:-\$

yes you can use the r/c controller from the car but not the motors.
You need to calculate the torque of the motor and the rotor width.

I shouldnt think that you could use anything but the transmitter/receiver, and even then its unlikely to have enough channels for a helicopter (you need at least 3. 1 for up/down. 1 for turn left/right. 1 for forward/backward)

SmAsH · « **Reply #3 on:** January 16, 2008, 03:50:46 PM »

hmm....point taken...but theres a copter that my friend has that has a height control lever on his controller and then one for forward and one for left and right...

making your own helicopter is advanced stuff.
Don't

yea ur right ill just mod one with lights

He probably does have a controller with 3 channels on it. But unless im mistaken, you were asking if you could use parts from a cheap $10 radio controlled car. The car will not have a 3 channel remote I guarantee it, I would even be surprised if the remote control unit operates with pots most likely it will just be metal plates giving only the option of full speeds or no speeds. Totally useless for a helicopter

for a heli you need at least 3 or 4 channels. 3 channels if you plan on having a gyro on it and 4 if you gonna try to do it yourself

you engineers and your calculating

if you are that much of a cheap!@# you COULD get rotors, take the motor and put it on a gear reduction unit with adjustable pinions,if your motor hits full rpm and seems like it could go faster, use a higher pinion, if the motor is getting too hot, use a lower pinion, however, this thing WONT stay level on any of the 3 axis, you need a balence and control system for that, a tail rotor, and either a coaxial blade or a variable pitch mechanism... all in all, save up 200$ and buy yourself a nice electric rc helicopter

awww how am i gonna get $200? anyway i'd rather spend that $200 on my own robotics

SmAsH . . . you should focus on just one robot idea at a time . . . I see too many of yours in the forum

saves me tons of time and money

its a bit hard to do at first . . . so thats why I made the calculator tutorials for you guys to use . . .

Ironically, a quadrotor copter would probably be easier to build since you don't need the cyclic control mechanisms. But lets see if you can afford 3 gyros and 2 accelerometers plus 4 brushless motors with motor controllers.

lol i normally get $10 a week and i work for my friends dad (at the factory) and he give me like $20-$40 an hour. and i get to keep a whole heap of free stuff...about $100-$300 of free stuff!

really 20 to 40 bucks an hour?

? Thats a lot of money man , work 20 hours a week after school and thats 400 - 800 bucks a week!!!!!
plus 100-300 bucks!!!!

is this a bit of an exaggeration smash ?

I don't want to hijack this thread but do you really need 4 gyros and 2 accelerometers for a Quadricopter? Also couldn't you just use 4 'helicopter' servos from servo city?

lol I forgot this thread was about copters

you need gyros for balancing the heli on each corner so you know how much thrust each propeller must be giving , 4 helicopter servos ... maybe gotta calculate the rotor length etc. before building a heli, and i doubt smash will make this heli

OMG ed I was cracking up, you know what , ed we need a webpage or thread devoted to all this funny pics we have posted in response to Smash's comments, so it will be available for any other memeber who would like to use a pic to prove a point , lol.

paulstreats · « **Reply #21 on:** January 20, 2008, 08:52:57 PM »

you could probably do with 1 3d accelerometer and 2 gyros (you can get 1 accelerometer and 1 gyro built into the same package).

2 gyros mounted at the center of the heli can do the same as 1 on each corner.

Another idea to reduce costs would be a tri - rotor system in the shape of a triangle

no what i meant in the previous post was that hes throwing out computers. i never said i got any! and besides this weekend was the first time i freakin worked there! also there are very little parts i can harvest from a pc....before this weekend i was only getting like $7 a week us ($10 aus)

that is totally wrong!!!! connectors , every passive component you could imagine ,and you could sell RAM online, hardrives online , etc.
with one computer I scavengede, I have taken so many connectors and SOOOO many sockets and capacitors, and switches, etc.

what happened to 20- 40 bucks an hour?

i got $40 for 2 hours yesterday and then went home got my dads credit card bought some stuff and taped $38 to it and said spent $38 heres cash! he was still pissed cause i didnt ask...lol. and omfg i thought the only thing i could get was big caps....and wires. can i get anything useful from a ps1? i have a spare one i can use...went inside it yesterday and all that was useful that i could find was ports, a motor, wires, wire connectors... please help me. BTW: i also have about 5 broken ps1 controllers

dewme5 · « **Reply #28 on:** January 24, 2008, 10:48:14 AM »

look at the really cheap helicopters. you only need 2 controls. up/down, left/right. forward is handled by being balanced a little nose heavy, reverse is handled by turning around. These toys are actually alot of fun for the $15 -$30 US. For the same price as getting something you have to re-engineer (car), you can buy a finished product that is going to work better for the same money.
