If the controls are operating backwards, you can correct this one of two ways. One is to reverse the servo arm(if it comes off one side only) or move the linkage to the oposiite side of the arm. The second option is to use the Servo reversing program to reverse the direction the servos move. If you have the manual(or can download it), the instructions on reversing servo direction is on Page 10. If you do EXACTLY what it says, you should have no problems .
