No disc will stay straight for most of the flight and then turn over at the end, not naturally at least. That'd go against the physics of disc flight. You could achieve that flight by throwing an understable disc on a low line with insane spin, but I somehow don't think that's the thing you're looking for.

Most discs that finish right (RHBH) need to either be understable and thrown on a low line with just enough room to flatten out of a turnover and not turn-and-burn, or need to be stable and cranked on a hard anhyzer to where they flatten out AND land at the same time.
You can do this with just about any disc. Here's a few usual suspects: Roadrunner, Sidewinder, Valk, Leopard - each will require different levels of power and different angles of release...and unless you are getting these in DX, you might need to give them between a few weeks to a few months of solid use before they'll work for this shot.
Skeeter, Kite, Warship and X Comet are some examples too.
Flat shots need running on the center line of the tee and planting each step on the center line. Anhyzer needs running from rear right to front left with the plant step hitting the ground to the left of the line you're running on. Hyzer is the mirror of that.
