making a simple little radio controlled robot truck

hi,

So after 5 years of programming I decided to buy electronics for dummies a few days ago.

I've covered more than 1/4th of the book, it doesn't however have anything on a radio control kit.

I managed to find a nice Radio Shack like shop near my place, they said they have RC kits but they asked me what kind i wanted!??

Could someone help me on this, I want to be able to send quite a few messages to the Truck besides direction, also, what kind of motors do i use for things like steering the forward wheels, or a little crane? are servos any good? and if my primary motor is controlled by via AC adapter, can I hook up two 9V batteries to power it?

Lastly would anyone know how I make design a little missile launcher that I could control via Radio?

Also any suggestions about what I should use for the exterior? I was thinking think ply wood?

Originally I wanted to make a little helicopter(I know a little about aerodynamics) I hope this will get me close to that, eventually I want to stuff in a micro controller so I can program the little vehicle, so is it possible to make a common internal design that I could fit into something else?

Thanks so much Gideon

Several things you should do:

- Buy some cheap radio controlled toys at the toy store and take them apart. See how they solve these problems.

- Visit a hobby shop that sells more serious radio controlled cars and models aimed at teenagers and adults. See the more complicated and expensive solutions used there (for example, proportional servos). Even if you don't have a store like this, there are a lot of mail order and online catalogs that would be educational. (for example,

You will also learn some things about structure there - for example, many cars are a tough chassis of fiber- filled plastic (or in the past, machined aluminum) that carriers all the components, with a lightweight vacuum-molded plastic shell that mounts on top. You can do vacuum forming at home.

- Decide if you want bang-bang controls, traditional pulse width modulated proportional controls (sequence of pulses one for each control channel, width of pulse indicates position), or if you want to send "messages" to a microcontroller which may simply decode them, or possibly execute more complicated 'robotic' functions
