Air frame - Error on V-Tail Mode configuration

Hi,

Please note that the V-Tail Fixed wing configuration file under Airframe is set up wrong in Px4 autopilot / QGC platform. While pushing the right remote control stick forward, the right and left V-Tail pushes down which indicates a downward plane nose movement and vice versa while the joystick is pushed backwards !
We cannot correct this using PWM_MAIN_REV 3 & PWM_MAIN_REV 4 as this will result in incorrect Yaw configuration for the plane .

Can some one correct this or provide a remedy for action .

thank you
