I get the helicopter after "The chase" mission. I proceed to fly it and land it where other runners do just at the base of the Vercetti Estate Stairs. Then after a few missions such as Supply & Demand... It vanishes?

Why is this? I need that damn heli for COP LAND!

So I just attempted my 2nd full run in Vice City. I was at 1:16 at the Cherry Poppers Dupe. I was hyped to get my 2nd ever run sub 1 hour 30. However, like the previous time, I ran into an issue with the cherry poppers dupe. More often than not I will not make it in time and get the call before I get back on the bike. No big deal here.

The big deal is I can NOT for the life of me figure out how to pull off the police cheetah method. I have tried so many times with NO success. I dont understand. I have followed many guides and videos from YouTube. There is no way at all I am missing something. I need some advice?

Also does anyone have a save for practice in Cherry Poppers dupe? The ones I tried were corrupt
