In Chained together you can make it on top of the elevator in 21 seconds but i cant do it i cant fly faster i can make it in 27 seconds or 26

You need to add strafes into the flaps to get farther. Strafes before it will make it faster. At least that is my current understanding of how it works. Hope this helps.

i can only do it at 23 seconds wr gets on at 19 seconds

23 seconds isn't bad. I was getting 23 seconds for a while. I actually did a run earlier where I made it to the first lift at 20 seconds. I think if you link the bhops together without missing you keep more of your speed.
