Dear gurus.
I am developing custom drone with A3 + Lightbridge with OnBoardSDK 3.3.1
I plugged my custom board to A3 API port with UART interface.
I have 2 problems with this.

1) After adjusing YAW
    All activation and controll is good with simulator.
    But after adjusting yaw value, the simulator drone moves different direction.
    I didn't take-off real drone in the air and sorry for this because I don't have profellers yet.
    Do you have any idea about this?
    Is just problem with simulator?
2) After power-off lightbridge joystick
    My aim is to control A3 when the lightbridge joystick is powered off
    But when I power off joystic, A3 itself comes home point.
    Is it possible to control my drone when joystick is powered-off?

Regards.

This may be a software configuration question. Have you checked the A 3 product page? http://www.dji.com/support/product/a3
