If you have not calibrated for a long time or the temperature difference has changed too much, you need to
recalibrate.
Sensitivity adjustment
Sensitivity adjustment follows a simple rule that the smaller the wingspan, the smaller the sensitivity; the faster the
flight speed, the smaller the sensitivity.
Two points to note for gain adjustment:
1
<BASE FUNCTION>---<AIL BASE GAIN> <ELE BASE GAIN> <RUD BASE GAIN>
:
The larger the value, the faster
the reaction speed and the excessive jitter.
2
<ADVANCE FUNCTION>---<STAB GAIN>---<FEED FORWARD GAIN>:
The larger the value, the faster the
response joystick will be, and the jitter will be exceeded.
Adjustment steps:
Step1: set
<FEED FORWARD GAIN>
,
normally reduce feed forward gain to 40
Step2: Set the
<AIL BASE GAIN> <ELE BASE GAIN> <RUD BASE GAIN>.
The span of 1m or less can set The parameter to
about 45. If it exceeds 1m, it can be defaulted.
After the parameters are set, you can fly test; firstly fly in
manual
mode, check whether the aircraft is
mechanically balanced; then switch to the
stabilization
mode. If the aircraft is found to be shaking during the
flight, reduce the sensitivity in the basic settings. If the aircraft is found to be unresponsive, then The sensitivity
of the basic setting can be appropriately increased; under the premise that the basic sensitivity is set, the size of
<FEED FORWARD GAIN>
,
can be appropriately increased. The larger the value, the more the aircraft follows the
action of the RC sticks, but too large will cause the aircraft to shake.

FLIGHT AND CONTROL
When a small arrow appears in the center of the screen, it indicates that FC has get “home” position; it can take off
right now. You do not need to check this if you don‘t connect GPS.
Auto TakeOff
①
AltHold Mode: Push the throttle to enough power and the aircraft will automatically climb to a height of 10m.
②
RTH Mode: Push the throttle stick away from the lowest position (
if the throttle stick is at the lowest level below 20m, the motor will never
start
), give plane a speed until motor start. It is recommended that the hand throw speed be 2-3m/s and the ejection speed be 10-15m/s.
set the take-off speed to 0 in the RTH mode; push the throttle stick to unlock the motor, shake the aircraft,
throw the airplane after the motor starts, the airplane will climb to 30m and start to turn
Throttle and speed control
①
Airspeed meter disconnect
Speed is controlled by the ground speed, curise speed is setted in
<ADVANCE FUNCTION>-<CURISE SPEED>.
②
Airspeed meter connect
Airspeed control keeps the aircraft from getting enough lift.
In the case of connecting an airspeed meter, the speed of the aircraft is determined by the airspeed meter, and
the airspeed is also controlled in the altitude mode. When the aircraft is less than
<MIN GROUND SPEED>
,
the speed of
the aircraft is kept at the minimum ground speed, preventing the aircraft from stopping in the event of a headwind and swinging
left and right. In general, it is recommended to set
<MIN GROUND SPEED>
to about 10m/s.
