This still doesn’t tell me if this is the reflex or zero position.
I also wouldn’t mind knowing from those of that have gone before me what sort of figures they have found to have worked for them.
I'll have to caveat that I have a RV-10, but since we share a similar wing and empennage, I'll give you the RV-10 answer.
reflex is when the flaps are even with the bottom of the fuselage
0 degrees is when the flaps are in the same plane surface as the wings. i.e. place a level on the wing and the level is sitting flush against the wings and flap.
When you move from 0 to the reflex position you should see -3 degrees on your level.
There are too many variables with the sensor that I won't go into details here. You really need to make the mechanical measurements first, then read the value of the sensor. Don't do it the other way around.
