The former X Factor star admitted that he was struggling to cope with the flying routine in the final because he suffers from bad motion sickness.
"I love the flying and to get to do it is an honour," Quinn told DS. "But I am scared of heights. I get sea sick, I get car sick. I don't like rollercoasters.
"You're all strapped in and it was hard to deal with at first. The more times I've done it, the easier it's become, but I'm still finding it hard to be delicate and smooth. I've got to get in that frame of mind."
Speaking about criticisms that he was already a trained dancer before the show, Quinn commented: "I thought myself, I would have an advantage as a dancer. But when you put the blades on and only have a couple of millimetres of steel, you are literally on the ice and dancing...It's slippy out there!
"Off the ice, I could dance all day. But on the ice, it's very different."
The Dancing On Ice final airs on Sunday on ITV1 at 6:55pm.
