The initial concept for the vertical and horizontal tail surfaces was based upon the conventional tail design option for the stock Cruiser aircraft. Since I need to be LSA compliant my aircraft requires a bit more wing area (an unreasonable 110 square feet) and that drives the requirement for vertical and horizontal tail area to be somewhat larger. After crunching the numbers a somewhat larger tail design was worked out along with a ventral fin to allow for more vertical fixed surface area. In addition to the larger vertical tail size, the aft fuselage was also stretched 24" to provide more moment arm. The vertical tail uses the full stretch to increase moment arm while the horizontal tail uses only part of it. The difference in aft displacement allows for an elevator without cutouts for rudder deflection and leaves less rudder blanked in a spiral dive situation.
