Changes made:

- All dead weight removed, because I dislike dead weight, especially when it makes up so much of the plane's weight

- The rear stabiliser was tripled. I arranged them so that you can select one by clicking the top, one by clicking the bottom, and one by clicking the back.

- The rear stabiliser wings were all inverted, so that they produce downforce instead of lift.

- The rear stabiliser control surfaces were limited to 10 degrees of motion to account for the fact that there's three of them now.

It's a little unsteady on the runway, but once you're in the air and get the landing gear up, you'll find a nice level cruise at around 190mph, with only mild effects about 30mph either side of that.
