its not a problem with joystick settings or anything, the f-18 doesnt work like the other aircrafts, thats the problem, if you touch the ground and you're not aligned, like one of your wings is higher than the other, and that makes one side of your landing gear touch the ground first, you'll slide. other aircrafts will correct their align as soon as they're on the ground, but not the f-18, and this needs a fix.
