 From a magnetic field vector we can only get two euler angles, so we would have to call roll=0, which would be fairly accurate in a stable, slow turning glider if we only wanted pitch and yaw to within a few degrees for flight stabalization (GPS would be used for the actual guidance). The following spreadsheet demonstrates the concept (although it hasn't yet been fully checked) Offset angle and incidence angle are set for UK conditions, and x_one, y_one are relative readings from the two axes of the compass module. The modulus of (x_one,y_one) has to be less than one, and some vectors give #Nan as they have imaginary solutions with roll=0, so any microcontroller on gumstick implimentation of this would have to have a sanity check\\

 **Roll** - The __Ailerons__ work in opposite directions to each other. When one is raised, the other is lowered.

 **Yaw** – If the __Rudder__ is moved to the right – the aircraft will rotate to the right. If moved to the left, the aircraft will rotate to the left.
