Accelerometer.. Which to buy?

mpu6050 position

I am a complete novice with this device. Have one and ordered 5 more last night after chasing down eBay prices. The angular velocity should be independent of distance from the axle but the changes in x,y,z should be much greater the further away from the center of rotation.

Should I start a separate discussion? This this to far afield from Aniss’s original question? Is there already a proper place to discuss the technical details. I have two robots (hexapod & balancer) that really could use a proper application of a MPU6050.
