Up and Down with Physics

I'm looking to create a jetpack like game. Right now I just testing controls using a little test copter to go up when I hold down the left mouse button.

I looked at the heli capx in the forums and tried to duplicate it but on pressing the left button my copter still falls.

I thinking I'm missing something pretty obvious because this appears to be something simple to do.

Windows 7 64-bit. latest stable C2

Here is a link to my one line cap.

Thanks

Your force is too small! Increase it to something in the hundreds and it works nicely.

Thanks so much for that quick answer. So like in the real world if my object were small it would require less force?

I'm not sure if I understood right, but I think you need to apply specific mass for the physics object to make it lighter. I don't think any physics engine calculates the mass from object's scale.
