Admin mode - fast flying not working

[Hugo]

It has been reported that pressing up on the D-Pad while flying allowed progressive increase of speed, although its not intentional it might help out:

Fly Mode Speed Bug... or Feature?

I’m not sure what happened in your game but if you press up on the D-pad while flying then you’ll go faster. You have to keep pressing it to increase the speed. Weeeeee there you go! It’ll reset each time you turn fly mode off and back on again.
