Hello, Just got my FC40 and it seems the functions of the controller sticks are the total opposite of all the info seen. Like to start the motors, they need to be pushed to upper right positions and upper inside left to shut off motors. All the videos show the sticks being pushed to the inside lower positions to start the motors. The left stick does not control the motor speed for take off. You need to use the right and left sticks together just right to get it take off and is very difficult to do. Any suggestions as to what might be wrong and how to fix?
