You are correct about the gyroscopic precession. It can be a large or small effect depending on the angular velocity about the y or z axis. there are other things that can also cause a turning moment. The gyroscopic precession is more noticeable in PA flying especially in the "squares".
You are also correct that the rules are silent on the matter of "scale speed" I have elected to fly at the scale speed for a couple of reasons. First, it results in a manageable lap time and pull at the handle. Second, I've watched many full scale aircraft flying at air shows where they are typically flying low and relatively close in. In model airplane scale model flying it has been my observation that warbirds for example are flown too fast to look realistic. I understand why and have been guilty of the practice. So, since realism is very important in our competition I have asked my flying buddies if Miss LA looks right at my "scale" flight speed. They think so. So that's where I am at the moment There has been much discussion in the r/c forums on this subject and I've not seen a consensus.

I appreciate the complement on the weathering. I have studied the subject and have found that most modelers tend to waaay over do the weathering of warbirds. The degree of weathering depends on many factors including the specific airplane, the theater of operation, the season and weather we're doing a German or U.S. plane. For example, I did a Ju 87G Kanonenvogel. I wanted to do a winter camouflage that is, in my opinion, very difficult to do properly. Germany did not expect the war on the eastern front to last long. When winter came the Luftwaffe standard camouflage didn't work on a snowy landscape. Their remedy was to paint the topsides with whitewash which mas not intended to permanent. As time wore on, the whitewash wore and washed away leaving a streaked and mottled dirty white with the underlying splinter camouflage showing through. Here is my interpretation of Hans Rudel's Ju87G Kanonenvogel as it would have looked in the spring of 1944.
