Direction Gyro seizes

[sfrayner]

I the P-51, P-47, and the P-38, when turning, the DG may or may not indicate a heading change. When it does, the DG after a moment, seizes and no longer follows the aircraft.  Is there a fix and is there a way to set the DG for the correct runway heading prior to takeoff?

I only tested this on these three airplanes.

This is a flawed implementation of the DG There are numerous reports of this . The explanation is that it is simulating Gyro precession etc. Though a DG just doesn't behave in the manner its modeled in the game. in fact the whole purpose of a DG is to remove this type of Turning and acceleration error you typically see in a straight Mag compass. In the Sim none of these errors are seen on the magnetic compass ... so effectively the Mag compass in the Sim is a much more stable heading reference to the DG .... the exact opposite of what happens IRL !
