How do I replicate high speeds of the pawn

I’m trying to create a flight sim, I mean I got the movement, but can’t seem to find the best way to replicate all that. My pawn simulates physics and to make it move I use AddForce and Addtorque once.

I would appreciate the help of network masters. My discord is qurtski just in case someone wants to help me deeply, as I’ve been struggling with this for about 3 months now and I got only client authority movement with little jitters.

I attached the way I’m doing client authority right now but I feel it would be better to have replication in server authority + client prediction with reconciliation. Of course I can’t find any source on how to do that in 202025.
