Since the latest stable X-Plane 12 release, it is impossible to start the engine manually from cold and dark. The starter cranks the engine, but it's like no fuel is injected (even with mixture full rich, selector on L or R, boost pump on and fuel press at 6 psi...). Starter works after Ctrlling-E and shutting down the aircraft.
In the latest beta, the same thing happens but the starting process still doesn't work after using CTRL-E.
Also, for some reason, fuel pressure gets to 6 psi when the battery is turned on, even without the boost pump on or the engine running...
Lastly, it is impossible to stall spin the aircraft. I can somewhat stall but the aircraft will always pitch down, even while turning. Spins are completly impossible to perform.
I always set my W&B to replicate the weight of my instructor and me and the amount of fuel and cargo we always put in our C23, and the real life vs sim configs are similar, so it is not a CG issue...
Is this normal? Should I enable the experimental flight model?
Thank you!
