Default Engine unloading and needle setting.
When setting the high speed needle how exactly should I account for unloading when the plane flies?

Normally I back it off about 500 RPM. That is for a 46fx, using low pitch props (4 and 5).

With a higher pitch (7,8,9) I'd expect more unloading. Say.. a 1000-2000 rpm increase for the sake of argument.

Does that mean I should back the needle off 1000-2000 rpm to accommodate the expected unloading?

What do people normally do?
