My multirotor does not hold
horizontal position well in
the Loiter flight modes
If you are using a high power video transmitter (especially 1.3GHz),
try hovering with your video transmitter turned off to see if the issue
goes away. If the transmitter is the cause, see the GPS Fix
troubleshooting section below.
Make sure your GPS module is getting an unobstructed view of the sky.
Make sure your compass is calibrated correctly.
Try adjusting the “GPS Position Hold” gain in the Advanced Stabilizer
Settings menu. We recommend you change this in 10% increments.
My multirotor does not hold
vertical position (altitude)
well in altitude hold modes.
Try adjusting the “Vertical/Altitude Gain” gain in the Stabilizer
Settings menu. We recommend you change this in 10% increments.
RTH: my fixed wing model
doesn’t fly home fast enough,
or flies home too fast
Increase or decrease the “Cruise Throttle Position” parameter in the
Advanced Safety Mode menu, or rerun the Receiver Analysis Wizard
and set a higher or lower cruise throttle position.
If high winds are causing slow return to home, you can program a
minimum RTH ground speed, by changing the “Minimum Ground
Spd(0 disable)” parameter under the Advanced RTH menu. If the
Vector detects the model is moving slower than this speed, it will
increase the throttle from the “Cruise” setting to the “Climb” setting
you provided when running the Receiver Analysis Wizard.
RTH: my multirotor returns
home too fast or too slowly
Increase or decrease the “Return Home Ground Speed” setting in the
Advanced RTH menu. It is recommended to change this setting in
small increments.
RTH/Loiter: My fixed wing
model turns too fast or too
slowly toward home, when
returning home or in loiter
mode
Increase or decrease the “Maximum Roll for RTH/Loiter” in the
Advanced RTH menu. The angle should be increased if the model is
turning too slowly and vice versa. It’s recommended you change this
setting in steps of 5 to 10 degrees.
Increase or decrease the “Turn Gain” setting in the Advanced RTH
menu. The gain should be increased if the model is turning too slowly,
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
