It would be nice that if using stabilization you can level the model at start up. I was thinking if during Spirit initialization and using stabilization,
the light would flash if model is out of level and it would stay solid if the model is level in all directions. You can take off under either condition. I currently use a 15mm round bubble spirit level and it works out well for the unit and a larger level on the Geolink. Makes it easy to level the entire model
