Compass calibration
    Please calibration the compass before the first flight or change a quite far from the original place.

     Please note: precision is plus or minus 10 degree, precision deviation is big, the compass need to adjust. 

   Compass calibration

     1. put the butterflyS on horizontal position, lock the motor.
     2. Keep touching the button on the receiver until the light flash,then release the button.
     3. Rotate the butterflyS 360 degree according to forward/ backward,left/right and horizontal level orientation, and all of the rotates are finish within 30 seconds, until the receiver is not flash, the butterflyS can fly.


 

SKYARTEC ButterflyS is a remote controlled Vehicles, and adopts multi-motor to provide lift force and control the flight.There are gyroscope (sensing rotational speed) and accelerometer (sensing acceleration or gravity)on the flight control board, these sensors can help the pilots to stabilize some inherent instability systems, such as multi-rotor copter. Pilots can use the remote controler to control the multi-rotor copter. Roll, pitch,throttle and heading can be controled by the joystick on the remote control, so it requires at least a 4-channel remote control and the receiver.

Product Features :
-   Compass Function:  open compass function, 4ch(center the direction channel), butterflyS at ground level, the flight attitude will come back to the attitude direction when power on the batterys. 
-  Supported 7.4V or 11.1V lipo-battery.  
- No additional welding
- Adopts excellent quality components, sta ble and superior performance. Use 32bit singlechip
- Integ ration of all components, adopts th ree-axis acceleration sensor and three-axis angular rate sensor
  (6 axis gyro)
- Easy to use and debug, applies to multifarious multi-rotor models
- 3 axia Gyro sensitivity and set the main function can be adjusted by the position adjuster
- Support for multi-axis X type
- Output ports have up to six groups, can d rive ESC or servo.
- Standard PWM signal output, support conventional PWM ESC (Suggest using SKYARTEC series high-speed ESC) and all kinds of servo (digital or analog)
- The receiver can be directly connected to the flight control board, without a special decoder, or alter
receiver
- The existing version can achieve stable hover and excellent handling (depends on a reasonable mix,
  commissioning and operational experience), the mode of operation is similar to the rc helicopter, but
  easier to adapt
- Can complete some incredible stunt flying skills, also can stable battery life, to meet small scope aerial
  photo to replace the complicated and expensive rc helicopter
- Support firmware upgrade (need to buy programming), and unceasing improving performance
- Self-stabilizing system, support fixed-point hovering
- Can quickly eliminate the inertia caused by flig ht, fast and stable.
- Have aerial photo PTZ link function CAMP CAMR
