With the rear of the airplane jacked up to the point that the leading edge and the trailing edge of the wing are equal, the leading edge of the horizontal stabilizer should be 3 degrees higher than is the trailing edge. In other words, with the airplane flying level with no input required from the radio, the tail should sit higher than dead level. This is to prevent the airplane from climbing uncontrollably when under full power. You really do need your incidence meter to measure this. If you have a flat bottom airfoil on the wing, you can get it close by having the bottom of the wing level, and then check that the Horizontal stab is 3 degrees up in the front. Do this before you install the elevator, or let the elevator droop out of the way. This measurement applies only to the non moveable part of the stabilizer.
