Spektrum SPMAR600 - Manual (Page 6)

30 paces (90 feet/28 meters)
1. With the model restrained on the ground, stand 30 paces (approx. 90 feet/28 meters) away from the
model.
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 at 30 paces (90 feet/28 meters).
4. If control issues exist, call a Horizon Product Support office nearest you. Contact information is
listed in the Warranty section.
Receiver Power System Requirements
Inadequate power systems that do not 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 AR600 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 you are using a questionable power system, (e.g. small or old battery, ESC that may not have a BEC
that will support high current draw, etc.), we recommended using a voltmeter 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: Nickel-Metal Hydride batteries, when charged with peak detection fast chargers, have
tendencies to repeatedly false peak. These include all brands of NiMH batteries. If using NiMH
packs, make sure that the battery is fully charged. Use a charger that displays total charge capacity.
Note the number of mAh put into a discharged pack to verify it has been charged to full capacity.
