Well Dave, you touch on a few points that I did not mention as there are many changes to the original design. First on the agenda the wings were moved from an S1-S position to an S1-T position, on the full scale this was to accommodate a much larger engine, and such is my position as I went with a much larger engine. Now as this has been done the math to correct the balance point was calculated as well as all other points. As for positioning of incidences these were set to a full scale's position as is most everything. I typically like to build scale and expect the flying characteristics to be the same, being such there should be no down elevator trimming required as a Pitts of this nature is typically a bit nose heavy. Thus my concerns about the down elevator, and it was the first I have had do this in 35+ years of modeling. Now I will say I may have jumped the gun coming on here and asking for opinions as I had not done much investigating into the issue. I guess I was just thrown for a loop with such as I thought everything was perfect by the math and such.

I will follow up with the issue next post.
