I am getting close to finishing my Turbinator and I need to set some down elevator mix with the flaps, may I ask how much down elevator are you guys using for half and full flap. I just need a good starting point and I will adjust the mix after I get a couple of flights on her. I balanced the plane 7" back on CG and I balanced it up side down, that seems to be better then right side up, I seem to be able to get a better balance point with the plane up side down.
