Triple Axis Accelerometer Breakout - MMA7260Q
sku: SEN-00252
Description: This is a breakout board for Freescale's triple-axis MMA7260QT accelerometer. With a low power shut-down mode, high sensitivity output with selectable ranges (±1.5, 2, 4, and 6g), this was one of the very first sensors to market with three accelerometers built onto a single IC! Board comes fully assembled and tested with external filters installed.
The MMA7260QT is a 3.3V part and outputs an analog voltage for each of the three outputs. This voltage is in ratio to the measured acceleration and to the supply voltage (ratiometric). You will need some extra hardware to convert this analog signal to a usable digital one. Luckily, many uCs have a built in Analog to Digital converter.
Dimensions: 25x25 mm (1x1")

yes the breakout-board has proper .100 hole pattern.
What gets me is that the signal is maintained.
What I mean as that the rotated along the XorY-Axis, the XorY signal is maintained.
If I rotate along the XorY-Axis, the output continues to be maintained *after* motion stops.(Z-Axis is not the maintained)
The device acts more like a 3-axis pseudo-gyro. I would expect an accelerometer to go to zero whenever motion is stopped.
My breakout-board does NOT do this(zero signal on stopped motion,) but that is OK for my application. Actually, this is great for me.

Thank you
The main issue is that the accelerometer measures the acceleration in xyz relative to the board, not the ground. You could very easily have the helicopter pitched up or down and still maintain 1g in the z relative to the board. If your helicopter is pitched over and maintains 1g in the z, contact with the ground will happen eventually.
