Built the J-110 Revenant, and while working on improving speed, I removed the leading edge slats (1x4 angles on the wing) and gained a minor improvement on speed. This also affects boats, helicopters, and about everything else in the game.

These are the parts I removed. I did this test with no payload, and no RATO pods.

Speed before removal: 1,284kmh

Speed after removal: 1,302kmh

This applies to all of the wedges except 1x1.

How to Replicate:

Build a plane, and make it have 1x4 wedges for wings.

Test speed of plane with and without the wedges, and its speed should increase without the wedges
