@TheCatch I'm happy if the problem solved! :D

@TheCatch No problemano neighborino

Thanks for the inputs @Kav and @Michiganstatepolicethe2nd ! I figured out that if I got a Fuselage piece and shaped it into a pylon figure, it could be directly mounted to the wing and engine which gave it more stability.

Did you turn down the mass on the pylons?

I watched video. Is pylon connected to something other than wing?

@TheCatch Km/h? It's low.

@Kav low 300s high 200s

@TheCatch What's its speed?

@Kav It was already set to Wing-2 lol.

Change the wing name in overload menu. It is probably named as Wing-3, change it to Wing-2.
