The mAh rating should be written on the battery. For Lipo batteries typically used in drones, the stated mAh is usually a fairly decent estimate of the actual, though that varies some depending on the brand and quality of the battery supplier and the current load and age of the battery. Even if there is no label on the battery, the mAh rating is typically ...

Brushless (BLDC) motors are not inherently directional. They can be either clockwise or counter-clockwise, it only needs to be set in the software, or by swapping two of the motor wires on the physical phase output pads of the ESC. The only time a brushless motor will care about rotation is if they have different direction threads on the shaft where the ...

You could use an IMU to measure the speed and position. You just have to:
Calculate the quaternion that represents your drone orientation, using a filter like the Madwick or Mahony filters.
Strip the gravity from your accelerometer raw data readings, the quaternion you calculated is what you will be using for this. It's not the only way, you could also use ...
