Beechcraft King Air 350i Propeller RPM/Throttle weirdness

I have searched these forums for a bit and googled other places as well, but I can’t find any solution to this problem I seem to be having. I know that Turboprop logic was updated last patch, but I don’t know exactly what that means.

Anyhow, here is my problem:

I push the propeller RPMs up to full after starting the plane. During taxi, the RPM seems to be staying fine (and the sound seems correct) and the speed is what I expect it to be, given my throttle. Then I fly my route and land at my destination. As I come off the runway after landing, and having brought the throttle back down to 0, the RPM remains super high (and the sound reflects this). During taxi i have to keep holding down my brakes to not go up towards 40-50 knots. It’d probably go even higher if I let it. And that’s at 0 throttle. Before taking off from my departure airport, the plane would be still at 0 throttle 100 RPM.

If I bring the RPM controls down to 0 and then back up to 100, it seems to fix the problem, but surely this shouldn’t be necessary?

Is this intended, even after the turboprop logic fix? Am I just missing something?

Hi
Just so you think you’re going crazy you’re not
I’ve had the same issue before though this was with a 3rd party aircraft…I would quickly cycle the prop lever and it would revert the throttle and engine sound back to normal .

I thought it was a 3rd party addon issue but obviously not

Your “throttle” (power setting) is never at 0%. I quit playing MFS a few months ago due to terrible turboprop inaccuracy, but idle power is set by the condition levers, were you possibly in high idle? If so try setting the condition levers to low idle.

This sounds identical to my B350 issues back in September-November '20 (after which point I switched to CJ4). So I assume not much has changed since then.

Sure, I can do that and it’ll probably fix it. But why is it different when I start taxiing at departure compared to the taxi after landing at destination?

Probably because there are so many things not modeled or simulated properly in this game. In the PT6’s I’ve flown the high idle condition is only used after start to get the RPM % up enough to get the generators online, and then they get set back to low idle. High idle is dang near enough power at idle to takeoff with and shouldn’t be used for taxi. But as far as why is it different during taxi and after landing, well, it shouldn’t be, and it’s probably just yet another inaccuracy of the game.

I’m having the same issue with the King Air 350i. Throttle is at roughly 50% even though the indicator says otherwise. Using the virtual throttle control to briefly set to reverse temporarily fixes it. Using a Logitech Extreme 3D Pro joystick.

I’m having extreme difficulty slowing the plane down for landing at SABA with gear, full flaps, and full idle it’s still zooming past the runway with with lift…something is off here…
