@atgxtg ok, thanks... i will try this!

The tilt to the right is caused by the bits of fuselage covering the horizontal stabilizers in the back. They are not lined up exactly the same due to a bug that happens sometimes in SP,You can test that by taking those two pieces off of the plane. To fit it, try redoing those coverings.

The poor take off performance is probably do the the high wing loading. Take off speed is tied to this. If you want to lower this speed then you need to lower the wing loading, either by reducing weight, increasing the wing area, or both. For comparison a tiny wing fighter, the F-104 has a wing loading of around 105lbs/ft2. If you want to keep the same basic wing shape, you can make the wings slightly wider and longer and then nudge the wing into the fuselage a little to hide some of it.

You could also improve take off performance by adding flaps (they can lower take off speed) by making the front gear higher than the rear gear (that pitches the wings at an angle and increases their lift during take off runs), or by changing the airfoil shape of the wings. Flat Bottom wings will give you more lift at the expense of top speed.

@Awesomegamer9786 thanks for the idea, but i already tried this.

Try making the the vertical stabilizer larger. My understanding is that it works kind of like the keel on a boat. But I’m no expert

Wayyyyy bigger wings
