travel
Travel adjust value is set above 100%
over-driving the servo
Set Travel adjust to 100% or less and/or

Aircraft suffers
from short range
Heavy use of WiFi in the vicinity, large
metal structures, concrete with rebar
construction, etc, poor environment
for rf.
Select a new location to fl y
Pointing the transmitter antenna at
aircraft in fl ight
Don’t point the transmitter at the aircraft in
fl ight
Sitting on the ground with the
transmitter antenna close to the
ground
Prevent the transmitter antenna from being
next to the ground when fl ying
