BreakDance Physic

Hello together, I am new at un real I can unfortunately not such good English but try to express myself well enough with the translator.

I am trying to create a kirmessimualtion currently I am trying to fix a gondola with physics on a cross what can swing freely tilted in the z axis by 14° degree unfortunately this does not work. also not if I lay a blueprinz for it where the crisscross and gondola is connected with a physic achnor. she always flies off or fidgets weirdly around. I don’t know what I’m doing wrong in the unity engine it works without problems but I want to do something with the unreal engine. can perhaps one help me or more accurately interpret how I fix a free-rotating gondola on your motorized cross ? Thank you;base64
