ISSUE DESCRIPTION M600 has such excessive idle thrust, that it is almost impossible to slow down during descent. Real turboprops should start slowing down rapidly when thrust is set to flight idle, because the propeller acts like a speedbrake. At lower altitudes, M600 can only descent around -300 f…

Should be fixed: [image] Expert Series, Famous Flyers, and Local Legends Aircraft Updates | 2026-08-14 Piper M600 Changelist v1.06 Fixed idle performance in flight, there was a bug where torque was not reducing to 10lbs as expected.

A windmilling propeller acts more like reverse thrust than a speedbrake. In any case, this seems excessively low. I don’t think there is any default aircraft in MSFS with accurate windmilling drag. I did some experiment with the TBM in FS2020 days, the conclusion was that propeller feathered or wind…

It is definitely frustrating having the throttle set to idle and the aircraft won’t drop below about 88–95 knots. I have done two legs of my around-the-world tour in this aircraft. Landing last night on a runway around 3,000 feet, it wanted to just glide along, and it took 1,000 feet to touch down; …

To me, it is probably the axis settings problem. But if I remember C208 def. what does also on taxi, I’m not surprised. They did probably some workaround with set some resistance braking effect on ground with TBM???

Out of curiosity, have you tried the same descent with the throttle axis temporarily unassigned and using keyboard idle only? I’d want to rule out a little axis noise or reverse/condition mapping before calling it purely flight model, especially because the Caravan/TBM have had similar odd idle or g…

Same here, but I think it’s rather lack of prop drag than excessive thrust. Either way, PLEASE fix! :folded_hands:

No, this has nothing to do with axis mapping. Disconnecting the throttle and pressing F1 yields the same result.

Hello everyone. I am a Piper M600 Flight Instructor and Pilot in real life. My simulator there’s the same problem. In the real airplane, when setting the power lever to idle, the torque must be 0 (zero). Thank you
