Once VIO gets enough features the drone becomes more stable but generally taking off in position mode often fails. We've recorded imu data via voxl-logger (200hz, --skip 4) and the chart looks extremely noisy<br />

We've also tried recalibrating IMU (voxl-calibrate-imu-temp and voxl-calibrate-imu). Could it be that the IMU sensor is damaged? What next steps would you recommend?</p>

<p dir="auto">Are you able to create a video of QVIO overlay which can be viewed through voxl-portal? As well as post a px4 log. It is better not to fly in VIO control mode until this is resolved (fly in manual thrust/roll/pitch/yaw mode and collect the log + video).</p>
