I end up using just the compass and course setter most of the time.
I just measure the angle on the map with the protractor, for example 125 degrees, then set the course setter to heading+10 so in this case 135 degrees.
By comparing landmarks i get into the general direction right after takeoff, then i just lean to the side with freetrack (can also be done with the mouse, hold the middle button down and drag the mouse left/right to lean) and look at the compass from zoomed out view. This way i can both keep the plane flying straight and look at the compass.
Since i have the on-screen systems messages enabled, i know what kind of heading i selected on the course setter. Then i just look to see if the 3 lines (the two "guides" and the actual T-shaped compass line) are parallel. Doesn't matter which angle you view it from, as long as the lines are parallel, you are flying the course chosen by the course setter.
I find it's much easier and faster than trying to hold the plane steady long enough to calibrate the gyro. I use this method on both Hurris and Blenheims. The Blen has a clear, unobstructed view of a secondary compass in the bombardier station, but i now find it easier to set a course with the course setter and follow it, than read the gyro.
