This is a proof-of-concept prototype plane I make for the upcoming SU-67 build, which is basically a tailless stealthier SU-57.

Currently having some problems:
1. The aircraft roll when the rudders try to correct it. (possibly related to the design of the aircraft)
2. I can't be too harsh with it cuz it can lose control very quickly and abruptly. (Sokolóv’s SU-67 is a high maneuverability plane so it must be able to handle abuse and rough flying)

Most of my previous flying wings or tailless planes are just tailless on appearance, they have hidden vertical stabilizers, but this time I want to make Sokolóv’s plane a pure tailless and use drag rudders to keep the aircraft stable, I want the aircraft canon to the story. I "borrowed" the codes from this plane, but I don't have any experience with the physics of a pure tailless so... I need some help guys.

Btw, the actual rudders are hidden the the fuselage, just in front of the engines, the outside wings are just for visual, they aren't functional.
