I have a feeling the plane had best be away from metallic structures, such as hangars, as far as possible?
In an ideal world, do it well away from buildings, on level ground, where you don't believe there are any underground power lines.
Normal good practice is to mark out lines you can align the aeroplane with on the ground - this is known as a "compass rose" (better still, find a local airport with one marked out already) and have somebody help align the aeroplane and keep sightseers away from the prop whilst you operate the aircraft and write the numbers down.
Oh yes, and use a brass or plastic screwdriver on the adjustment screws, not a steel one!
