Before I get into target operation and manuevering (sp), I would first like to get the Copter to atleast hover on its own under the programmed codes.

Running it through my head, I figure what I would need for this, simply to get the Copter hovering on its own, would be the Copter, ADXL213 Dual-axis Accelerometer or Memsic 2125 Dual-axis Accelerometer, whichever I decide to use to balance the Copter out, and the Microcontroller along with all the programming sofrware. If there is anything I am missing, please let me know. Again, thank you all

Take care

At minimum you will need three gyros and three accellerometers. It took me about 3 hours of flying time to hover a battery pack without crashing. That's flying time, not counting time spent waiting for spare parts. Micro helis are so cheap becase they make money on the spare parts. As Ken was saying, any change in roll or pitch requires an increase in throttle. The best analogy I've seen is balancing a marble on a piece of glass. I'm not going to say it can't be done, but it will be very difficult. As I said in a previous post, it's not just controlling the heli, its being able to carry your sensor and processor payload too. A micro heli can only handle a couple of extra onces of weight.

Go to http://rcgroups.com and visit the micro heli forum. There is a sticky with a PDF called the "Electric Helicopter Beginner's Guide". Essential reading.
