A Rotor RPM gauge is so basic and fundamental for helo flight, it borders on criminal that the gauge is missing from the 2D gauge set.
Novice & Advanced model both need 2D gauges-including a Rotor RPM gauge.
ONLY the flight model physics should change between NOVICE and ADVANCED flight model, not options like 2D gauges.
