While there are many that use a RevMax and flat 100% throttle curves and are happy with it, Model Avionics, the manufacturer of the unit says that that is not how it is designed to be used. If you want a governor then buy a governor.
The Rev Max is designed to be used with functional pitch curves and just give that little extra to help prevent over speed in the cases where you can not get the throttle curve just right, like in a power decent.
You will actually get better performance buy using a governor as a governor and a limiter as a limiter.

I am lazy and do not want to spend a month setting up perfect Throttle curves so I buy only Governors. I have both TJ Pro's and GV-1's. The GV-1's are easier to set up and use and the TJ is more accurate. I have not personally used any others so I can not compare them.

A R30V1 still has a 5mm spindle and you say you are running wood blades.
Regardless of blades used, with the 5mm spindle and plastic head block I would not run over 1750.
