I would say keep hucking it, but yes there is more to it. Make sure you aren't throwing them sketchy, so make sure your backflips are clean as a whistle. Try doing cork sets, like 3s to your back. When you wind up to huck stay coordinated and get lots of pop. Be able to spot your landing and stomp it.

More tips:

TUCK

Make sure not to huck too hard or you will probably land on your side or back.

Make sure your wind up coordinated.

Try to float them on bigger tramps if you are sure you aren't going to land on your head.

It might also help to reach for a safety.

Take a video of yourself and see if you are going to flippy or spinny, then correct.

My first cork 7 on a tramp was just a few weeks after my first backflip, and I didn't really know what I was doing until I filmed myself, video review is important. Once you have the rotation they are pretty easy, but it I still slip out when I land if i have soft socks on.

Hope this helped

Do a T set 7 (arms straight out) leaning slightly back, but at 270-360 pull your legs up and tuck.

I learned them on the trampoline by breaking them down into a 180 to misty. That's not exactly the movement but it works for learning. To learn a misty you do half of it and land on your back/shoulders. Then just jump a little higher with the same motion. Same thing for cork 7s. You do a 180 to half misty to get a feel for it.

throw a 630 over your shoulder and bring it to your back. get comfortable with this rotation and gradually bring it to your feet. this is how i learned.
