Final answer:
If the airplane's controls are correctly set but the cables are rigged tight, the airplane will be heavy on the controls, making it difficult to fly hands-off.
Step-by-step explanation:
If the travel of an airplane's controls is correct but the cables are rigged exceptionally tight, it will have the probable effect of the airplane being heavy on the controls when flying. This means that the pilot will have to exert more effort and force to control the airplane's movements. The tight cables create more resistance and make it difficult for the pilot to fly the airplane hands-off.
