Well, lets assume it is anti-gravity, which of course will only work in the presence of a gravity field. Now out in the depths of space long long ago in a Galaxy far far away, there is precious little gravity to go around, the best you could manage would be a gentle wafting to the next star. You can't build an interstellar Empire/Republic at sublight speeds.
So anti-grav to take off - max acceleration 1G BUT only directly away from the planet (assuming a roughly Earth type planet). Now due to the inverse square law, once you have doubled your distance from the starting point on the planet surface to the core, say at 3500 miles altitude, a mear nothing in interstellar terms, you are only getting acceleration of 1/4 G
Fire up the the phallic symbols on the back for a bit of forward motion, maybe using a couple of auxillary anti grav units positioned front,rear,port, and starboard, to give you directional control(basically use the whole lifting body as a control surface). Then when you're up out of the atmosphere fire up then Hyperspace engines for some superluminal travel.
The real tricky bit is going to be the yaw just after lift off, not going fast enough for any usefull aerodynamic effects, maybe need a little bow thruster as used on boats.
Edited for inverse square law thingy, which I remembered just after pressing submit........
