I fly Revs/Octanes.....but I think any 4 line hybrid with decent depower will work the same.
Generally you should be paranoid when you're doing a self launch. It's pretty easy really but I'm always worried about getting a line wrapped on the bar or bridle just when I'm powering up. Happened a couple times and almost wasn't pretty. Also, there's nobody that's going to tell you that your lines are wrong or you've got a bridle wrap, so make sure you've double checked everything before you try it.
Until you get some practice, probably better not to do it unless conditions are ripe, ie sideshore and you're launching towards the water. Walk your lines til you're to where you would normally have somebody launch the kite for you, then walk just a bit more up until you get the kite to roll and start to gently fill.......keep the line tension on it, and walk (or RUN) back so that you're in normal launch position relative to the kite and coax it up......
The hybrids have enough depower that you can generally get away with this even if it powers up a little bit hot downwind, just make sure you're letting the bar all the way out and steer it to the side of the window. Be ready to punch out. Make sure you have wide open spaces in terms of hard objects/people to the lee, both for your own protection and other people's.
Landing just bring it down fairly hard in the same area that you would if somebody were catching it for you, but grab and pull both center flying lines a bit before it hits the ground so that you can get the leading edge to ground, be ready to gank the flying line on the side of the kite you want to pull towards you hard so that it doesn't roll back up. Run like hell to secure your kite before it relaunches, preferably walking up the flying line to keep it from relaunching, but you'll see a lot of people skip that once its down ok. Hard to do if you're overpowered.
Definitely better to do some practice with a friend there ready to grab your kite and even more preferable to watch somebody do it that has your same kite. Eventually you'll find yourself in a situation where you have to do either a self launch or land by yourself, so it's good to know how to do, but it's always safer to have somebody lend a hand.
That's especially true it you're on a narrow beach (which a lot of times means a bluff causing super flukey winds) or onshore conditions, which means hard objects somewhere close by. Some places are easier to land than others.....if you can drop the kite into the shadow of a bush or some other object, that's a lot less stressful.
I'm sure somebody will chime in about launching/landing by using your chickenloop hooked or clipped onto something, but I read this as a question about how to do it without any aids at all.
Here's a Caution video that's pretty good on self landing:

Don't blame me if you mess up. I'm just saying this is what I learned by asking others to show me the technique and then observing.....don't be afraid to ask, as this is one skill that learning by trial and error is probably....an error.
