    It seems to me, from watching both real world shutdowns of PT-6 type engines as well as other turbine simulations (
    X-Plane and DCS) that the engine shutdown of the turbine Duke is too fast. The slowdown and the sound effect seems unnecessarily and unrealistically rushed.

    I wish that weren't the case, and given that the gyros take 30 mins to wind down, clearly realism is highly valued.

    Could this be fixed, if I'm correct?

    Hi,

    I love the new Dukes.

    However I have issues with the slow propeller spool up of the engines on the turbine Duke during start up and the long delay during shut down after moving the condition levers to cutoff. The engine should should commence to shut down almost immediately when the condition levers are brought to the cutoff position.
    Although I have never flown a Duke, I have over 1000hrs of C208 Caravan experience and it's PT-6 engine.
    If the devs should read this forum, then please take another look at the above.
    Thank you!

    @Super27 This is because you are in the beta range and not in flight idle. The lower 15% of your hardware throttle axis is assigned to the beta range. So if your hardware throttle is at idle, the Dukes throttles are not in flight idle, but at about 0 degrees pitch in beta. You can hear a distinct click when you move the throttle over the gate from idle to beta. This is a compromise to accommodate as many hardware options as possible, as described on page 77 of the manual. In flight idle the timings are much more accurate.

    @Super27 Outermarker's reply is correct. Your engines ARE shutting down, but because your props are not feathered, they take a long time to spin down. His procedure will solve the issue for you.

    Hi,

    Thank you for your explanation!
    After moving the throttles out of the beta range, the engines stated and shut down as expected.
