SN-L user manual 

 

 

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. 

七、

 

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 

 

AltHold Mode:    Push the throttle to enough power and the aircraft will automatically climb to a height of 10m. 

 

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 

 

Airspeed meter disconnect 

Speed is controlled by the ground speed, curise speed is setted in 

<ADVANCE FUNCTION>-<CURISE SPEED>.

 

 

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.
