All measurements are approximate figures.
Tests were performed with 2 Pythons mounted externally with a centerline mounted E-20 at 16,051 lbs--standard weapons load. The closest airport temperature was 11 deg C and 29.92 in Hg.

Flying Controls: The Logan has a redundant fly by light control system. The dogtoothed (vortex generator for higher AOA) main wing is a two section flap and aileron (aileron out board, flapervators in board) with spoiler/speedbrake that occupies the entire trailing edge with full leading edge slats. Assorted vernier thrusters assist in pitch and roll control in atmosphere. This aircraft features a two segment modified Pelican tail. The inner portion is all moving on a hinge, which moves with trim, and features a conventional elevator while the top portion is an all moving tail to control yaw. Outboard of the main wing also has drag rudders to assist in yaw control.
