The back is twisted a lot as far as I'm concerned , but I don't know if it will be a big problem. I wouldn't know how to fix if I had to anyways. I just put this together and see that it is much worse than any of my other planes. I do have the skyfly max that the vertical fin is not even close to 90 degrees and it flies just fine (the elevator is level)

Here's a pic so you can see just how bad it is? How would I fix this anyways? How will it act in the air if I leave it? I'm guessing the whole rear is twisted 3 degrees or so and the wings seems level with the fuse.
