$40 Six DOF IMU
For $40 USD + shipping you can grab a Walkera UFO replacement PCB which has three ENC-03 piezoelectric gyroscope sensors and a MMA7260 triple axis accelerometer sensor on a daughter-board. This is a great deal considering the prices of these components individually. However it took over a month for Walkera to backorder and then ship it.
The daughter-board can be de-soldered from the main board and it also has a bunch of passive components for some noise filtering. Ive tested this daughter-board and the signals are well within specifications. Heres some more info about this board.
The main board also has a PCM receiver that you can desolder and use with a PCM transmitter.
