Are you sure? yes | no
tips from experience:
* Be sure that your sensors are sending data fast enough so that you avoid oversampling your data which will completely negate your kalman filter.
* Be sure that you aren't exceeding the range of what your sensors can measure.
* Record your flight data for post flight analysis. This is the most import part!
