@TechnoMax This is not a fault of my mod, it happens with the base cars including the Mach 3. Tell Erathor about this problem.

Everything about the car is awesome except for one thing. The wings seemingly extend instantly, so holding the button down causes them to extend and retract over and over again.

So you've got two options:
1. Press the button for a fraction of a second to extend the wings.
2. Press the button and have a 50% chance of extending the wings.

If you fix this one issue, this mod is absolutely worth installing.
