The methodology is to put a straight edge on top of the horizontal stabilizer and make the elevator flush to that straight edge. This makes it look a little strange from the bottom, but it flies well this way. I can remember reading a post here some while back of a builder that decided the stab should not be built that way and spent quite a bit of time rebuilding the plane to this new configuration ( he flipped the stab over and installed it upside down). I never heard how his flew after all that work. Mine flies very well in this stock setup.
I have a P-60 for power, which makes it scoot pretty well. I don't think it would do well with a smaller turbine.
