Reinforcement for VTOL Wing twist?

Hello all,

I am looking for recommendations regarding reinforcing a VTOL’s wings to limit wing twist.

wing layout can be seen in the following post:

My question is, is it possible to limit twist by using vertical carbon strips spaced 3 to 4 cm apart from the wing root to the VTOL arm? I am already using some clear covering film on the wing but the wing twists around 4 to 5 degrees during yaw.

Any suggestions will be appreciated.
