Tried that got a "mate, we don't want to be in the low 2000 rpm region for prolonged time as this is the resonant frequency of the fuselage and we'd like to avoid inducing ground resonance"
But from various hover square practizing one learns that indeed there is a sweet rpm setting at full pitch down, that will result in perfect rpm for hover, w/o having to mess with the throttle.
Of course, FI was fully aware of that trick and required me to roll off the throttle before commencing takeoff.
What might sound like hostility was part of his training regime.
He'd admit that he'd have the governor removed from a would be training S300Cs,
as "you guys should learn proper rpm control ab initio"
