True Fruitbat but for now when flying on 20 rpm engine sound is so weak that i think it will die. Only when i look at my speed gauge and see it is around 400 kph on 5% nose up i realize that engine is alright .
Most important thing is when in dogfight your rpm goes to extremes, low or high, so you constantly have to change your pitch to correct RPMs actually makes this plane hard to fight in. So my suggestion is to not engage in turn fight, just let him be with his energy and settings and engage only when in domination over enemy in altitude.
