 The big Hartzell propeller creates a propwash that affects the inner ailerons, so they remain effective even when the airflow over the wing is next to nothing. | |
 |  |
| The unusual two-part ailerons allow the inner part of the aileron to fly at a different angle of attack from the outer part. | |
 The small surfaces known as “spades,” attached beneath the lower wings, act as an aerodynamic counter-force, keeping control inputs light. | |
 |  |
| The newly designed “3-D” carbon-fiber tail was inspired by remote-control aircraft and allows Tucker to make large deflections for low-speed maneuvers. | |
