2. Face the model with the transmitter in your normal flying position and place your transmitter
into range check mode.
3. You should have total control of the model with the button depressed at 30 paces (90 feet/28 meters).
4. If control issues exist, call the appropriate product support department.
Receiver Power System Requirements
Inadequate power systems that are unable to provide the necessary minimum voltage to the receiver
during flight have become the number one cause of in-flight failures. Some of the power system
components that affect the ability to properly deliver adequate power include:
•Receiverbatterypack(numberofcells,capacity,celltype,stateofcharge)
•TheESC’scapabilitytodelivercurrenttothereceiverinelectricaircraft
•Theswitchharness,batteryleads,servoleads,regulatorsetc.
The AR6115/AR6115e 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
If a questionable power system is being used (e.g. small or old battery, ESC that may not have a BEC
that will support high-current draw, etc.), it is recommended that a voltmeter be used to perform the
following tests.
Note: The Hangar 9
®
Digital Servo & Rx Current Meter (HAN172) or the Spektrum Flight Log
(SPM9540) are the perfect tools to perform the test below.
Plug the voltmeter into an open channel port in the receiver and with the system on, load the
control surfaces (apply pressure with your hand) while monitoring the voltage at the receiver. The
voltage should remain above 4.8 volts even when all servos are heavily loaded.
Note: The latest generations of Nickel-Metal Hydride (NiMH) batteries incorporate a new chemistry
mandated to be more environmentally friendly. These batteries when charged with peak detection
fast chargers have tendencies to false peak (not fully charge) repeatedly. These include all brands
of NiMH batteries. If using NiMH packs, be especially cautious when charging, making absolutely
sure that the battery is fully charged. It is recommended to use a charger that can display total
charge capacity. Note the number of mAh put into a discharged pack to verify it has been
charged to full capacity.

QuickConnect is designed to allow you to fly safely through most short duration power interruptions;
however, the root cause of these interruptions must be corrected before the next flight to prevent
catastrophic safety issues.
Note: If a brownout occurs in-flight it is vital that the cause of the brownout be determined and
corrected.
