I've been doing some testing in order to calculate fuel burn.
Setup hind on "Take off from parking hot", increase game speed to 20x, all controls neutral, no collective being pulled.
9 times out of 10 one of the engines will catch on fire before i've burned through all of the fuel.
I've tried using dust protection and messing with the anti-ice settings to no effect.
For further information i have been doing this test on Persian Gulf, Liwa AFB, PRK 36, Weather 14.3 T °C, Light Scattered 2 at 8202 Feet, QNH 29.92
Best regards
