Nowhere near as understable as the numbers suggest. This is a great straight to fade fairway out of the box. The one I have is quite flat, almost puddley in the middle of the flight plate with a little bit of shoulder closer to the rim. Feels nice in the hand.

Firstly, I'd like to mention that I'm not entirely sure if I have a normal Relay. Mine from the Gyropalooza box (2022) is surprisingly stable. Released flat, it will have a small amount of turn, but fades back reliably. I really enjoy the feel of this disc. It is flat, the rim width is in that sweet spot for me, and the plastic is top notch. This surprisingly became my most reliable and farthest flying disc in my bag. I'm not sure if I have a griffin disc or what. If I put it on hyzer it stays on hyzer, it does not flip up. If it put a touch of anhyzer on it, it will turn for a bit before fading out at the end. I need to snag another Relay to test with and will update this review in the future. Mine is 169g for reference.
