I insist all my students know what the static RPM limits (fixed pitch prop) are for the aircraft they fly. It is considerably lower than the redline. For example the C 150 has a 2700 RPM redline but the POH lists the static RPM as 2460 to 2560 RPM. I teach all my student that as soon as the throttle has reached the full in/forward position (after being slowly and smoothly advanced at the start of the takeoff role) they check the RPM (looking for static RPM value) and engine gauges (looking for all in the green) and verbalize the call "good engine". In molesworth 1 case I would expect my students to have rejected the takeoff at the engine check point because the RPM would have been at or over the redline RPM and therefore not at the expected static RPM value.
