Stalling with C152 in SU8

I heard that new propellor mechanics were introduced with SU8. Guessed I’d test this out with the C152. Now to be honest, I hadn’t tested this before so maybe it’s an old issue:
Take the plane to 2500ft QFE, reduce your engine full and keep the plane level as it looses speed till stall. Like in real life, the Cessna will dip one wing that you need to counter with the rudder and then pitrch down, pick up speed and gradually level off. When done correctly you shouldn’t lose more than 500ft. However with the sim, you can counter with the rudder but then the plane will pitch down violently and enter a spin. Impossible to exit.
This is not my experience from real life (I wouldn’t be here typing :slight_smile: )

Are you a student or what certs do you have? I’m a student on 150s so I’ll have to try this.

yea, the spin characteristics are awful haha. It becomes un recoverable. I didn’t look at the weight and balance so maybe its the CG is off. The hardest part of the flight model to accurately make is the spin characteristics because there are so many variables at play. It’s still annoying when I just want to do one for fun, but it becomes un recoverable so easily. Just spins straight to the ground. The nose is down so it’s not like its flat or anything.
I know that’s not what happens cause like you, I’ve done multiple spins irl and am here to tell the tale.

I’ve clocked about 300h as a PPL(A) pilot and like most, started on the C150 so quite distant memories :slight_smile: Same goes with flight sims. The reason I was optimistic is because my memories of XPlane were that the flight model was really good and that they were the first to integrate sophisticated airflow and prop mechanics so when I saw that Asobo was tackling this, my hopes where high. Guess it will take a few cycles before they crack this…

There’s a plate on the instrument panel with the spin recovery instructions printed on it. Something must be fixed if these instructions don’t work correctly. :upside_down_face:

You might want to move your topic to the bugs & issues category so that people can vote on it.

I guess this is the same cause as described in my thread below. There are no reactive control surface forces simulated. Therefore the yoke does not move out of itself causing the aircraft to enter a spin.

See here:

I haven’t tried it with the new prop effects yet, but my earlier spin recoveries were fairly straight forward using the PARE technique

Power to idle
Ailerons neutral
Rudder opposite direction of spin
Elevator forward to break the stall

Once that is done, pull up gently to stop the dive.

I have a hard time telling which way is forward when I’m upside down and backwards :grinning_face_with_smiling_eyes:

I was able to recover from the stall/spin every time in the C152 at 2,500ft, but I’m not a real pilot and probably doing it wrong.

I tried this in the Cessna Caravan at 27,000 ft and it didn’t go well at all :sweat_smile: With all the noise and creaking going on, I can’t believe I didn’t get a stress failure.

OK, don’t know if there was a silent fix but just tried the stall again with the C150 and this time it worked as expected! I managed to do all the routine stall recovery exercises and in addition recover from a spin so good job Asobo :slight_smile:
