The illustration below shows how my heli flies when I go into forward flight. The red line is the flight path and the heli is canted off to the side a little. Constant rudder/tail rotor pressure is needed to fly in a straight flight path as well. I have trimmed the rudder but it requires more or less depending upon throttle input. More throttle = rudder and vice versa. Is this normal or do I need a Gyro adjustment? If so how?
