I'd say build it! The rudder isn't terribly important for most stunt designs,
and the error in area is only a small percentage.
If it really bothers you, simply cut a new one..
I seriously doubt that anyone will be able to look at the finished model
and notice anything different.

"It's the notion that there is no perfection - that there is a broken world and we live with broken hearts and broken
lives but still there is no alibi for anything. On the contrary, you have to stand up and say hallelujah under those
circumstances." - Leonard Cohen
