KMS Corsair 'Wings' Question

I deleted my Gunslinger a long time ago, but what I recall was that it did High Jump if you were on the ground, and it would start floating if you held the key down.

So it functioned the same way it does in the videos?
Or did it only float after that high jump?
And was it in KMST or KMS?



If anyone can provide a screenshot or a video would be better of wings in action that would be great
