Receiver Power System Requirements

Some of the power system components that affect the power supply to the
receiver include:
• Receiver battery pack (number of cells, capacity, cell type, state of charge).
• The ESC's capability to deliver adequate voltage to the receiver when the
servos demand high current
• The switch harness, battery leads, servo leads, regulators etc.
The AR637T has a minimum operational voltage of 3.5 volts; it is highly
recommended the power system be tested per the guidelines below.
Recommended Power System Test Guidelines
We recommend performing the following tests on any new setup to verify
power system performance:
1. View the receiver voltage during this test on your transmitter's telemetry
screen
2. Load the control surfaces (apply pressure with your hand) while monitoring
the voltage at the receiver.
3. The voltage should remain above 4.8 volts even when all servos are loaded.
How QuickConnect
• When the receiver voltage drops below 3.5 volts, the system ceases to operate.
• When power is restored, the receiver immediately attempts to reconnect.
• If the transmitter was left on, the system reconnects typically in about
4/100 of a second.
QuickConnect is designed to allow you to fl y safely through most short duration
power interruptions, however, the root cause of these interruptions must be
corrected before the next fl ight to prevent a crash.
NOTICE: If a brownout occurs in fl ight it is vital that the cause of the
brownout be determined and corrected.

Glossary

AS3X- Stabilization technology that dampens wind and turbulence. Designed to
support advanced fl yers, AS3X does not include self-leveling technology.
SAFE Envelope- (Intermediate Mode) Stabilization technology that uses AS3X
to deliver normal fl ight performance, but with limited bank and pitch angles to
prevent the airplane from getting into extreme attitudes.
SAFE Self Level/Angle Demand- Stabilization technology that will make the
airplane return to level fl ight when the control stick is centered.
Panic Mode- Sometimes called a bailout mode, Panic is a SAFE stabilization
mode that can return an airplane to level fl ight from any attitude. It is usually
assigned to a momentary button.
Flight Modes in Receiver- Determine what stabilization modes the aircraft
operates in. All the associated stabilization features to tune the fl ight stabilization
can be adjusted per Flight Mode in the receiver (Base Gain, Priority, Heading, etc).
Flight Modes in Transmitter- Manage rates, expo, voice/sound output, and
other transmitter based confi gurations.
