Due to gyroscopic precession and the torque of the engine, when a heli is in hover and the swashplate
is level... it will naturally roll to the left. We are compensating for this by adjusting the position of the
servo arm on the spline to naturally be tilted to the right,thus tilting the whole head to the right. If the
head spun counterclockwise, we would tilt it the opposite direction. When you replace the Elevator
(fore/aft) servo arm, have it
either level or slightly tilted forward with the stick and trim centered. Maybe 23
°
. If you did change the
landing struts as in the prior chapter and the whole machine is tipped a little nose down, make the
elevator servo perfectly level... this is one of those things you have to use judgment.
Now do the “false flying” one more time and see the difference. Does it still feel sensitive? Yes, it is!
For actual hovering indoors or without wind, you only need 10
°
maximum deflection on the swashplate.
Out of the box, the swash was bottoming on the chassis, there was no way in hell you were gonna fly it
if I couldn't! I recommend you get a new set of
Walkera output arms.
