HingeConstraint Instability

I don’t usually make posts, but this, this is different.
So I have a building game, this is the jet engine part from the game.

One day, out of the blue, this jet started shaking violently in specific peoples’ vehicles on specific computers at random. What’s most interesting, is it seemed to stem from a jet I built in this game and shared with a friend, that jet, even today, cannot produce any thrust.

However, in some vehicles, in seemingly the exact same conditions, it has no problem. Today though, like an infection, that has propagated to all vehicles made in my game. Now I’m mad.

I have had this problem for nearly a year now, I’m stumped. I’ve tried everything, even remodeling. I have updated this game’s propeller logic about 50 times already and it has managed to break in each iteration. It’s as though, this size, form factor and shape is just aggravating the engine?! Someone save me from myself because I’ve up to and had it with this darn hunk of inconsistent metal. Sherlock Holmes would be clueless in the vicinity of this object. This could be a keter level anomaly in the SCP Universe. Scooby would get his snacks taken away by this abomination. Roblox, explain yourself, what is this!?

TLDR:
I understand that I need to provide more instructions for reproducing this ‘bug’ yada yada. Someone please just give me a new idea to throw at this; open the place file, set the Jet.Hinge.HingeConstraint AngularVelocity to 100 rps, observe and go ham on it. I give up, I quit, I resign.

why are you using a hinge for that
you should probably use a CylindricalConstraint with ActuatorType on Motor

Why would I use a hinge for a rotor that rotates in a fixed plane relative to its stator? Well, because it rotates in a fixed plane relative to its stator of course. But, interesting idea, yielding the same issue, although slightly better.

Also most other motors in game can have a propeller attached to the front which will produce an equal and opposite reaction force on the motor shaft since the propeller is pulling the vehicle forward. So, the jet would elongate slightly in this case. Although idrc.

Why a CylindricalConstraint, do you think I did it wrong here maybe?
