Hi, in your blueprint movement logic you could increase your turn rate (how much of the axis value you plug into the Add Controller Yaw Input). Then increase the Max Acceleration in the character movement.
Then you would fly like on rails (but would always accelerate instantly not only in curves). If you also want to stop immediately when letting go of a movement button you might also want to increase the Braking Friction Factor in the character movement.
Else what you could try (if you want to only make the curves sharper but not all acceleration) you might want to try this:
Get your current velocity and your velocity if it would go into your actors forward direction. Then lerp those two. You may wanna change the Interp Speed. But with that setup you would not be able to move sideways.
