Quick tuning tip

You give us a short description of your problem, one or more pictures of your rig and (if possible) send us a blackbox log showing the bad behavior. We will throw our years of experience on it and give you a hint or two about what filter-settings and PID-parameters to change to get a better flying bird.

This requires you to be willing to learn about tuning and experiment with various settings but in the long run you might gain some knowledge that enables you to help other pilots in your group.
