Airborne vehicle with multi-airfoil tail

An airborne vehicle comprising:

• a body section;
• a main wing extending from the body section configured to generate aerodynamic lift, the main wing comprising one or more main wing control surfaces;
• and
• a tail assembly extending from the body section aft of the main wing, the tail assembly comprising:
• (i) a first tail member horizontal stabilizer having a substantially uniform first chord length;
• (ii) a second horizontal stabilizer having a substantially uniform second chord length, wherein the second chord length is substantially equal to the first chord length;
• (iii) a first vertical stabilizer;
• (iv) a second vertical stabilizer;
• and
• (v) a third vertical stabilizer, the first horizontal stabilizer being substantially parallel to the second horizontal stabilizer, the first horizontal stabilizer having one or more control surfaces, the second horizontal stabilizer having one or more control surfaces that comprise one or more flap surfaces selectively deployable between a retracted position and an extended position, the one or more flap surfaces being configured to increase at least one of a surface area or camber of the second horizontal stabilizer in the extended position, and wherein each of the first, second, and third vertical stabilizers is connected to and extends between the first horizontal stabilizer and the second horizontal stabilizer.
