Asking the smarties on here.
I fly a Nanchang with a stock M-14p motor and an MT 250 prop. When I push the nose down my RPMs increase without touching the prop lever.
Assuming the governor is set up properly, if my RPMs increase when I go downhill would it be a spring issue in the governor?

Presuming you have the "Stronger" spring GiL.

I previously had an MT250 fitted as well even with the Stronger spring it exhibited a little of this behaviour.

I now have a 265cm MC400C from Whirlwind aviation fitted it still exhibits a little of this.

(BTW IMO the Whirlwind prop in formation (Straight and form aeros) is a dramatic improvement over the previously fitted MT prop, and far more robust in rain etc)

Yes, I sent the governor to MT for a stronger spring.
