Trick used by Von Braun on Redstone when experienced failures of
graphite jet vanes was to glue cardboard covers on the vanes
Cardboard would burn off after few seconds , but would protect the vanes

Jet vane problems surfaced during flights of JUPITER C test vehicle
JUPITER C was Redstone missile which propellant tanks was lengthen by
about 2 meter to increase burn times
Extra burn times caused erosion in jet vanes leading to the cardboard “fix”

Why not use paddles rather than vanes? They only enter the hot gas stream when actually thrust vectoring. This reduces both drag and overheating.

I think you should gimbal your Motor. You only need two larger servos instead of four and you don’t have to worry about the vanes burning away. The fuel and oxygen lines would require a flexible coupling but this can be done fairly easy. I remember watching one of your videos with your Motor setup to gimbal? Why didn’t you keep testing it? SpaceX used the gimbal method on there Grasshopper Rocket which was used to verify the landing software which is now being used on their Falcon 9 rockets.
