proportional to speed squared formula to calculate the speed at which
the stall will occur at the max g that you wish to subject the airframe
to. Two times stall speed would be 4 g.
ie if you are below the maneuvering speed it will stall before it will
bend with ailerons neutral. Realistically I'd use a bit lower than that
number to account for control (aileron) deflection in turbulence. 4 g is
a bit lower than the 4.4 limit that is used for some airplane classes
IIRC so twice the stall speed may be a pretty good number.
Not sure but I think I just put the top of the green ASI band on a
number that I pulled out of the operating manual for the Rebel.
There is a very detailed flight test manual for amateur aircraft that a
fellow was selling in Toronto but I can't seem to find my copy right now.

How does one determine best maneuvering speed when doing flight tests? I
see that AC 90-89a says (page 34) that it should be estimated at 2 x
estimated stall speed. That's it though, no suggested flight test profile
to fly to determine maneuvering speed. Manufacturer (me/Murphy) can't state
such since there are so many variances out there (wing tips, VG's, droop
leading edge, etc). Suggestions for determining this value?
I'm getting ready to fly soon-but no, not today.
