F5C being buggy

So today I took out the F5C to grind like I always do, but I noticed a few problems.

First: I get fuel starvation the very second I start turning or go upside down.
Second: You lose the controls of the plane once you go -1g’s.

Is this a bug that appeared after the recent update? Yesterday it was fine, today it’s not.

HI, i’ve looked in patch notes since this post is pretty old and i didn’t find anything so i went to test it myself.
I didn’t see any issue with your first problem and for ur second issue your crew might need training.
Hope this helps. :)
