I doubt you'll be able to measure the true tilt of the plane, but
fortunately you don't have to.  I would control the ailerons (the control
surfaces used to tilt left/right) simply to keep the accelleration vector
vertical in the left/right direction.  All you need for that are two cheap
accellerometers.
