Modification of an APM 2.5 Flight Controller
Custom firmware allows sampling and storing raw accelerometer data at 1000Hz
Mount developed to secure sensor to aircraft
FFT performed on data to determine frequency of vibrations

Verticality During Testing
Vibration table created from speaker and frequency generator
Data from accelerometer z-axis, oriented vertically
Data proves sensor is accurate and samples at 1000Hz

3. Aircraft Ground Testing
Aircraft secured on ground and run for five minutes
Data from accelerometer z-axis, oriented vertically
Fundamental frequencies at ~51Hz and ~91Hz with others being harmonics Z X Y
