The legal speed limit is 99 .... you need to fly at approaching that kind of speed ideally.
While you are learning, I think the landing gear down restricts your speed anyway. You can take off from the pad by using vertical thrusters (that's R on my keyboard), then move forward to avoid banging into anything above your head.
Reminds me of docking back in the Robigo smuggling days in a stupidly fast Asp. Boost at the slot doing close to 400, then as you cross the threshold, a quick FA-off 180 flip, FA back on, gear out,
