add Force but in the direction of a gameobject

Hi, i tried to create a helicopter. all fine, apart from the force upwarts. if i use: … AddForce(0, someValueToTakeOff, 0); the helicopter takes off but straight up. is there a way to make this dependend to how the heli is rotated?

Sry, if there are any misstakes, english isnt my first language.

Thanks for your help :slight_smile:

Your English is great! Try replacing AddForce with AddRelativeForce.
