ISSUE DESCRIPTION

Description of the issue:

SU2 MSFS 2024
When starting the engine on the Cessna 172 classic (premium deluxe version msfs2024)
the propeller animation is not working correctly: in the cockpit, the animation wont start, the engine starts,but propeller not moving. Now if I go to external view, the propeller animation goes to 100% but stays like that, when I pull back the throttle the propeller animation should also go slower. However the prop animation is stuick either on 100% or off. Same when shutting off: The engine shuts off, but propeller animation is still 100%.

If applicable, which aircraft is experiencing this issue:
Only the default Cessna 172

has to be due to the aircraft model not fully loaded/streamed when starting a flight
next flight was ok
another flight not

ISSUE DESCRIPTION

Description of the issue:

I completed a simple flight-seeing mission in a C172 G1000 and then tried to do a second one. The system assigned me a C172 IFD, and when I started the engine, the propeller stopped turning (the engine was spinning, but not the propeller). This problem propagated to all aircraft except the Nemeth H135, for example (I didn’t try them all). I first deactivated the Cessna IFD, but that didn’t change anything. I then deactivated my community, and the propeller worked normally. I reloaded the exact same community, and everything worked normally again. I did a first flight, and when I tried to start the second one (via the main menu), the propeller was blocked again. This happens with or without the community, but not every time. It seems that I need to change the aircraft variant via the main menu.

FREQUENCY OF ISSUE

Maybe at every second flight

YOUR SETTING

[PC Only] Are you using Developer Mode or have you made any changes to it? No

[PC Only] What GPU (Graphics Card) do you use? RTX5070

[PC Only] What other relevant PC specs can you share? I7 10700F 32Go Ram

8

I can confirm that starting to play with the C172 IFD locks all the propellers in the game.

9

I also confirm that if I start with a C172 Classic, the propeller works, but if I then choose another aircraft via the main menu, its propeller remains fixed, except for certain third-party aircraft such as the Nemeth H135 or the Inibuilds YS-11.

10

Is this in free flight or career ?. Have you disabled all your addons (community/Marketplace) ?

11

Both mode. It’s the same with or without the community folder activated.
