Physics Movement Thrust hover

So I'm trying to figure out the best way to do the following movement, very new at construct so if this is easy I am a newb.

1. Looking for a button press, this will engage the thrust slowly that pushes a craft up, but also accelerates as the button is held

2. Left and right keys would move the craft side to side

3. Letting go of the thrust and the craft would slowly decelerate to the ground.

Best way of doing this? Any help would be awesome Thank you in advance!

Also the movement would side to side would rely on the thrust, I guess think of a single engine space craft, would just tilt to move sideways, I know there are games that use this, i just can't think of the name of them :/
