and vice versa. It’s recommended you only change this setting after
failing to fix the problem by adjusting the “Maximum Roll for
RTH/Loiter” or if increasing that setting could create a stall risk for
your airframe. Adjust this setting in about 10% increments.
RTH: My model pitches or rolls
(banks) too sharply or too
shallowly during RTH.
Increase or decrease the “Maximum Pitch for RTH/Loiter” and/or
“Maximum Roll for RTH/Loiter” settings in the Advanced RTH menu
RTH: My model climbs or
descends too fast or too slowly
during RTH
Increase or decrease the “Desired Climbrate” and/or the “Desired
Descend/Sinkrate” settings in the Advanced RTH menu
RTH/Loiter: my fixed wing
model circles too widely or
too tightly around the loiter
or home point
Increase or decrease the “RTH/Loiter Circle Radius” setting in the
Advanced RTH menu.
See also the steps for troubleshooting if the model turns too fast or too
slowly, above.
GPS: I am having trouble getting
a GPS fix. Or, once GPS fix is
acquired, it is periodically lost,
or the GPS position seems to
move around quite a bit when
the model is stationary.
Always keep the GPS/MAG as far away from your video transmitter
antenna, and your video camera, as feasible.
If you are using a 1.3GHz or 900 MHz video transmitter, it is probably
generating spurious noise on the frequencies used by GPS. A good
description of the causes and solutions of this problem is located here:
Try testing the GPS with as many devices powered down as possible and
then add them back one at a time, and look for GPS degradation. Note: You
can connect the video output from the Vector’s "Video Tx" connector
directly to a monitor or goggles to test powering off your video
transmitter.
Audio: I hear static, buzzing or
humming only when the OSD is
showing information on the
video screen.
Increase your Vector “Black Level” setting in the OSD Setup menu.
If you don’t have the audio input of your video transmitter connected
to anything, try connecting it to the Vector Audio Harness, and
plugging the harness into the Vector’s audio port, as described earlier.
Audio: I have set up voice
alarms, but am not hearing them,
or they are faint.
Verify that “Mute Voice Alerts” is set to “No” in the
Audio/Variometer Setup menu.
Increase “Set Voice Alerts Volume” in the Audio/Variometer Setup
menu if the sound is too low, compared to your microphone
volume.
Verify that your wiring is correct. Especially, make sure that the
audio channel (left or right) that is coming from the Vector is the
same one you are listening to on the ground.
Video: I am seeing video
“smearing” or lines on the video
screen, that correspond with the
Increase your Vector “Black Level” setting in the OSD Setup menu.
