Optional Accessories - Horizon Hobby Spektrum AR637T Manual

Heading- An optional feature of AS3X, heading will make the airplane try to hold
its attitude when the control is relaxed. This is not a self-leveling feature, it only
makes the aircraft track accurately.
Gain- Tells the stabilization system the level of damping it should provide.
SRXL2- A Bi-Directional data communication protocol that enables digital devices
to communicate over a single signal wire.
Forward Programming- Programming directly on the receiver from the
transmitter. The receiver has all screens, menus and settings in its internal
memory. The receiver is using the telemetry link to the transmitter for the
interface, the screen and buttons.
Throttle Cut- Disables throttle function
Oscillation- Sometimes called a wag, this is a back and forth movement similar
to a vibration that may appear like a wobble. It may occur around any axis, roll,
pitch or yaw. It is most likely to occur on one axis, not all three.
Overshoot- When the stability system makes corrections it is a balancing act,
if the response is too strong the system will go past where it should stop, this is
called an overshoot.
Angle Limits- Only available in SAFE modes, these values defi ne the limits for
the bank and pitch angles.
High Thr to Pitch- This setting defi nes the angle the airplane will climb at when
the throttle is raised above half. This is only available in Self Leveling modes.
Low Thr to Pitch- This setting defi nes the angle the airplane will descend at when
the throttle is lowered below half. This is only available in Self Leveling modes.
Brownout- If the receiver power supply drops below 3.5volts, the receiver will
not have suffi cient power for operation and the resulting loss of control is call a
brownout. A brownout results from an inadequate power supply to the reciever, it
is a failure outside of the receiver.
