RE: AXE CP Gyro
The Gyro that is inside the Axe CP is built into the CCPM board and the Gyro on this board uses no moving parts. The Gyro you posted (I am assuming because I don't know what brand/model etc) uses moving parts which draw more power. There are different types of Gyros, such as heading hold. It makes flying more stable. The Gyro in the Axe CP is pretty powerful, I turned up the gain on my Axe CP and it became much more stable.
