As per the [Pitch Curve] window settings in page 6 in the manual, this is expected.
I set up the Heli using the manual . Now when I power on the radio and the Heli the main blades are positioned in a negative pitch and the servo isn't at 90 DEG.
Where in NORMAL mode you have:
IdleUp 1 and 2 you will have full negative pitch for inverted flight:
You can change the pitch curve to your liking. If you want less negative pitch in NORMAL mode, then increase bottom two numbers.
You should see the blade pitch change while doing so. Just make sure to keep throtle-collective stick at its lowest position.
The swash is also not level.
Engage-Enable THROTLE HOLD (motor is disabled) and verify that when throtle-collective stick is moved from full down to full up, the swash remains level and or travels equally.
At center position (50 setting in pitch curve) you should have 0 degrees of pitch. Otherwise a link might be off by a turn or two or a servo horn is off by a spline.
