Many stability issues can be traced to airframe vibrations. This is true of both flight stability and camera stability. Whether you're using a Hoverfly flight controller, a HoverflyGIMBAL, or both, vibrations are the enemy of optimum performance.
We have taken some precautions against vibrations already, both in the software and by providing anti-vibration grommets for mounting your Hoverfly product. Here are a few other steps you can take to reduce vibration in your aircraft:
1. Regularly check your props to ensure the are balanced.
2. Regularly check any connections (nuts, bolts, etc.) and make sure they are tight.
3. A piece of double-sided foam tape or anti-vibration gel between the board and the mounting plate will help to isolate the controller from vibrations.
