Is it possible to pass the forces in the earth fixed coordinates axes base? (in Newton or pof)?

I think this could be easily faked. e.g. new_roll = old_roll + cos(old_roll) * force_in_y_direction * a_magic_constant * dt but i f I read the code correctly, yaw and hdg are pointing at the speed direction (slightly filtered)? Therefore we need something like _elevation = atan2(force_in_z_direction,force_in_x_direction) and then your filter to add some inertia? > I haven't a great deal of time available in the run up to > Christmas so no promises on completion. > Same here.
