Okay, let's back it up some. You say you're struggling on the run out, but in all reality your problem most likely stems from far above that. When you huck any cliff, from 4' to 40', you need to have a good approach and launch, which is going to make the landing and recovery much, much easier.
What is a good approach? Well, the best approach starts the run before. If possible, check out as much of the lead in as you can. Ski as far down to the cliff as you can without committing to going over it. Ideally, practice in spots that are discrete boulders/overhangs, things you can ski right up to the lip of, but still bail to the side without committing to the huck. Then, ski around the drop, and thoroughly scope the landing. On both sides, be looking at how you're going to ski it. What line are you going to take into it? What angle are you going to drop? Most drops, the ideal angle is not straight out from the cliff face, but some type of oblique angle. Approximately where are you going to land? What do you need to expect to encounter immediately upon landing? It is so helpful to be ready to tackle what you're going to hit, rather than having to think about it and improvise in the moment.
Once you have your line scoped, ski the line as you planned it. When you launch off the lip, you need to be aggressive. Every ounce of instinct is going to tell you to lean back as you go over the lip. Ignore that. Drive forward as you pop off the lip. While it feels like you're taking a swan dive off the cliff, you're really getting your body angled so that you'll land centered on your skis, and not on your tails.
If you have gone over the lip correctly, you're going to land in a good position to maneuver your skis immediately, and while you will absolutely be going fast, you'll still be able to control yourself.
Long story short, the biggest reason you're feeling out of control on landing is likely because of a bad launch. If you're too far back, you land on your tails. That means you need to recover and recenter yourself on your skis upon landing before you can make any kind of maneuver. At the speed you're going after landing, there isn't time for that. So you lose control and crash out.
I've been hucking drops for a couple decades, and I've spent the last decade teaching kids ages 5-15 how to huck. Leaning back on launch is the cause of about 90% of all problems I've encountered when you're hucking.
