" Sperry problem 'work around', and useful tip "
As a number of people have noticed with the Sperry on the B-25, when you try to adjust the heading with the mouse it tends to move in 5 or 10 degree jumps.
Thanks to my good friend Norman Hancock of "DC-3 Airways", we have a solution, which is not exactly a fix, but a very effective "work around". If you have a "Wheel Mouse" which most people seem to have, just place the pointer over the place where you would normally click and roll the wheel. You will now get a very fine adjustment.
This also works on many mouse points on other gauges.
My thanks to Norm for finding this solution and sharing it with us.
