    Aircraft Gyro Horizon - DIY

    You will have a problem with accuracy as accelerometers are vibration sensitive and inaccurate in yaw axis. MEMS gyros (like all gyros) will drift, so in quadcopters they use 9DOF, 3axis accelerometers+ 3axis gyros+3axis magnetometers with all sensor results being passed to Kalaman filter for reasonable accuracy. i believe that modern avionics like garmin 1000 use similar approach.
