It would be nice if we could tune the flight computer without just launching it. Well, you can do that with the built in simulation in the Tektite-A App!
Theory can only take you so far
When you look back at the flight data for future flights, you may see some oscillations in the canard angle. If they are small then it is most likely fine, but if they are large, you probably want to reduce your controller gain.
Note that you can visually see the movement of the canards in flight using the “Flight Replay” button that shows up when you view a graph while connected to Tektite-A!
