orientations (nose up, nose down, nose toward the Tx, nose away
from the Tx, etc.) while watching the red LED, noting any correlation
between the aircraft’s orientation and when holds occur. Do this for
one minute. The timer on the transmitter can be used here.
4. After one minute, release the range test button. A successful
installation will yield the following: no holds, no flashing red LED.
If any holds occur, redo the test, noting the orientation of the aircraft when the
holds occur. This will allow you to change and optimize the antenna position(s)
to a better location.
Step 10. Short Test Flight Verification with Hold Indicator
When the system tests successfully, it’s time for a short/near test flight. This
first flight should be close (less than 200 feet) and about five minutes or
less. After the flight, land near yourself and check that no holds occurred.
A successful flight will result in 0 holds. Extend the flight distance and times,
checking the Hold data after every flight until you are confident with the results.
Y-Harnesses and Servo Extensions
IMPORTANT:
When using Y-harness or servo extensions, only use standard
non-amplified Y-harnesses and servo extensions. Amplified Y-harnesses
may cause the servos to operate erratically or not function at all and should
not be used with Spektrum equipment. When converting an existing model
to Spektrum technology, ensure that all amplified Y-harnesses and/or servo
extensions are replaced with conventional non-amplified versions.
Preset Failsafe
The AR6260 features preset failsafe on all channels. Preset failsafe is ideal for
sailplanes, allowing the aircraft to automatically dethermalize if the signal is
lost. With preset failsafe, all channels go to their preset failsafe positions if the
signal is lost, preventing a flyaway.
Receiver Power Only
• When the receiver only is turned on (no transmitter signal is present), all
channels have no output signal. This prevents overdriving the servos and
linkages.
IMPORTANT:
Some analog servos may drift slightly during power-up even
though no signal is present. This is normal.
After Connection
• When the transmitter is turned on and after the receiver connects to
the transmitter, normal control of all channels occurs.
• After the system makes a connection, if loss of signal occurs, Preset
Failsafe drives the throttle, aileron and elevator servos to their preset
failsafe position set during binding.
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
