Gyro Vs. Accelerometer
I build my quadcopter from scratch....Used Arduino Mega and Uno, and HMTR for Remote control...
Now, during flight, I got to realize that stability is done with IMU's such as gyrosensors and accelormeters...
So, I'm if have to choose between these two sensors, which one is the most to control its stability to hover, and how it can be done!
Need fast and better suggestions!
Thanks, all

If you feel you have to choose between the two perhaps you have not diiscovered that you can have all four for less:

accel, gyro, magn, baro for $12. Can't beat it with a stick.
I didn't checkn the obex, but the four devices on the board are fairly common. We're slowly working on drivers in propforth. There is already a driver for the bmp085 already in the propforth download. Its usually just a matter of taking the time to read the datasheet, and start experimenting, which I haven't gotten to yet.
