Project Parts List Help

Okay,
I'm trying to build a Quad Rotor Helicopter, I've made a couple entries on the forum but they haven't been very clear. I'm having a very difficult time putting together a parts list from Parallax. I have 4 brushless motors, 4 speed controllers, and a bunch of sensors including: the GPS module, an Accelerometer, a Gyro, a compass module, 5 ping sensors, and a TSL1401 Linescan Imaging Sensor Daughterboard. There will also be 4-5 servos, an SD Card reader with about 4gb of memory, and either an 11.1v battery or a 14.5v battery (both are lipo). Now, the hard part for me is that I need the thing that controls all of that, I need a propeller chip, but I'm not familiar with it at all. The only thing I'm pretty confident with is the BS2. So I'm having a little bit of trouble figuring out what I need in order to get all this stuff hooked up and working. I know this is asking alot, But if someone could please help me out with this, you would help me so very much, and every bit of time is very much appreciated.
I'm not a very experienced person with soldering or anything like that, so a breadboard for now would probably be best...
I have a half decent 3d model of it, I'll attach a picture of it if you need to know what it looks like.
If you have any questions or any suggestions about anything please feel free to email me or reply as soon as possible.
Thank you.

For a propeller based board, I would look at:
http://www.parallax.com/StoreSearchResults/tabid/768/txtSearch/Stingray/List/0/SortField/4/ProductID/584/Default.aspx
Should have all the I/o's you need, I think. (I didn't add all of them up yet).
Or you could pack it all on a Proto Board:

There is a BS2 oblect in the Object Exchange that could help you make the transition:
http://obex.parallax.com/objects/30/
but i feel·it would run out of steam in a short while with all that tou want to do. Spin would be better, and PASM even better.
But just get started putting the pieces together. One step at a time.
Jim
and also I'm not very good with soldering or very experienced with assembling circuits...
What is "Spin" or "PASM"
Start with making an I/O list
4 motors, 3 I/O each
5 servos, 1 I/O each
etc
when you have the list, and final I/O count, post again, and we'll try to help [noparse]:)[/noparse]

Once you have the hardware put together, you'll need to program the propeller chip. Spin is the native Parallax programing avenue for the·Propeller, just as the Basic Stamp Editor is use for programing the BS2 chip. PASM is the assembler tool used to create programs to run faster on the Propeller chip, faster than Spin.
·Keep the questions coming, as Bill said, we are here to help.

Jeremy, do you have a look at this thread?:

Then learn the program the propeller, flash lots of LEDs and such
Then try interfacing with each of your devices.
Then you can think about quad rotors!

Here's the kit: http://www.parallax.com/Store/Microcontrollers/PropellerProgrammingKits/tabid/144/ProductID/415/List/1/Default.aspx?SortField=ProductName,ProductName
now for what I have planned for this project, How far do you think this kit will get me?
Begin with the PE kit and look at the PE kit Labs it is very usefull for learning with the Propeller.
Coming from the BS2 I found it nice.
Go step by step . Take some time before starting the quad rotor project.

I think that would be a great way to start, you can learn how to program the propeller, then play with all of your peripherals and then you will be ready to move on to making something that might fly. At that point you will have to abandon the bread board because it will be rather heavy, a cut down protoboard is an easy way to get something light and easy to deal with.
