What is the Active Flight Stabilization (AFS) system?
A: The system consists of special sensors, mounted on the bottom of the fuselage, that send information about the model’s orientation to its radio receiver. The AFS offers an incredible advantage for inexperienced R/C pilots. It doesn’t fly the plane for you—it’s not an auto-pilot—but if you get into trouble, you can be confident that the AFS will help you get out safely.
Q: Why is it called “ACTIVE”?
A: All R/C trainer planes are designed for stability. Wings are positioned at the top of the fuselage to keep the weight suspended below. That gives the model a natural tendency to fly level. Trainer wings also have lots of dihedral—they angle upward away from the fuselage—which also increases stability. Both of these elements, however, make passive contributions to the flight characteristics. They don’t take direct action to correct specific problems your plane encounters during a flght. The AFS does: It actively searches for any signs of instability, and responds at once to help you recover.
Q: How does it work?
A: As mentioned, sophisticated sensors are a part of the model’s on-board electronics. They’re always alert, always ready to make any adjustments necessary to restore level flight. You still have priority control of the NexSTAR whenever you move the transmitter sticks. But when you don’t know what to do, release the sticks—the AFS comes to the rescue!
Q: How does the AFS
help me learn to be an R/C pilot?
A: Initially, it gives you confidence—when you get into trouble, the AFS helps you get out. Its sensitivity can also be adjusted to help you learn one of flying’s most important skills: avoiding over-control. It takes a while to develop a patient touch on the sticks. Your early moves might be a bit eager, and you’ll need the AFS to step in quickly to help. Gradually lowering its sensitivity, however, will keep you in sole control longer…like any good teacher,
the AFS gives you more time to "get it right” on your own.
