I’ll stick my neck out:
Required to get it off the ground – non. Just don’t go too high, far, or for too long in the air as it is all guess work. Personally, I’ll see you if you get back.
Minimum to get me in it (if allowed by law, which it is not where I am) – Engine & rotor RPM; but then I am not going far or high in that state
Minimum “sensible” day VFR for me – Engine & rotor RPM, Magnetic Compass, Altimeter, Air speed indicator, fuel gauge, engine temp, oil temp / pressure for engine & MRG (or warning lights)
Required by the manufacturer – consult the POH; different for day / night VFR or instrument
Required by law – consult the POH (see above) and national law, also different depending on country (and day / night VFR or instrument
I would also “like” to have: Vertical Speed Indicator, Slip ball, Artificial horizon, Gyro Compass, low/high rotor audible warning, battery voltage, MRG torque.
Happy to be "beaten up" on that list
