●Direction check: Controlling the throttle, make sure the quadcopter
doesn't leave the ground. Slightly move each stick to observe if the
quadcopter moves with your stick input direction. If the direction is
opposite, please change the channel direction on the radio.
Low altitude Test Flight
●After unlock, control throttle to make the quadcopter maintain a 0.5
meter altitude. Observe if the quadcopter is stable. If it’s not stable,
you need to adjust the sensitivity of the FC450.
●The channel center point can differ depending on the choice of
radio brand, the installation of FC450 can also cause deviation. If
the quadcopter has deviation after take off, please adjust the trim
on radio to find the center position.
Adjust the sensitivity
●450 class quadcopter can use the default setting to get a good
flight performance.
●The weight on the quadcopter can differ depending on the choice
of battery. This will impact center of gravity, and the flight
characteristics. To improve flight performance you can address the
below.
●Normally, if the sensitivity is set too high on the “pitch” (elevator)
axis, the opposing axis (i.e., aileron) will vibrate; if the sensitivity is
set too low on the “pitch” (elevator) axis, the opposing axis (i.e.,
aileron) will respond with delay to stick movement.
●If the sensitivity is set too high on the rudder axis it will cause the
motors to over react, which will make the quadcopter unstable in
pitch and yaw direction; if the sensitivity is set too low on the
rudder axis, the quadcopter will have difficulty on tail lock.
●When adjusting the sensitivity, don’t change the setting value too
much, 5-10 degrees a time is enough. When you find a stable
range, then tweak it for optimum performance.
Caution
●Please don’t pull throttle to the lowest position during flight, it might
cause the motor suddenly be stopped and crash the quadcopter.
●When you fly in high maneuvering condition for a long time, the
external acceleration will cause the FC450 cannot maintain a
horizontal status. It’s normal, hovering the quadcopter for few
seconds, FC450 will adjust the quadcopter to complete horizontal.
