blade angle on a seneca

[aslan1982]

if you were to pitch up in a seneca what would happen to the blade angle

what I know is the

blade angle = angle of attack plus helix

the seneca has a constant speed unit that keeps the angle of attack to its optimum by changing the blade angle.

On take off the blade angle is set to fine pitch = low blade angle
and during cruise the blade angle is set to coarse = high blade angle

as forward speed increase like on take off the blade angle starts to move towards coarse

so if i pitched up speed would decrease so the blade angle would move towards fine which would reduce the blade angle???

Please let me know if my understanding of this is correct.

Thanks in advance
