Here's some advanced tricks.
Switch Flatground 540: I can do this trick, but I've only landed it a dozen or so times. Start riding switch, then jump as high as you can and spin as fast as you can. Get the first 180 out of the way, then do a backside 360. Wind your arms a lot. This trick is really hard to learn. If you're having trouble, practice spinning without the board. I can do a 900 just by jumping without a board, so that really helps me.
Flatground Frontside 360: For this trick, get really good at doing frontside 180's off ramps. Then simply jump and do a frontside 360. That's all there is to it. What makes this trick hard is the fact that most people can't spin frontside very fast.
Backside 540: For this trick, do a backside 360 then pull the board an extra 180 and land it. I've only done this a few times, so I don't have much experience, but I can tell you that it is difficult. Get a lot of air and spin fast. It's all about practice. If you have access to a foam pit, great, that will help you a lot because you don't have to worry about getting hurt.
Frontside 540: I'd say this is easier than a backside 540, but you have to be really good at frontside 360's. Do a frontside 360, then rotate that extra 180. It's easier because you can see the landing at the end. Again, this trick is all about practice.
Backflip: I can't do these yet, but I found a helpful article on the internet that I'll summarize. Basically you should try it into water or a foam pit, or even on a snowboard first. Then try it on a mountainboard, and just stay calm, becasue it can be pretty scary. Go up to the jump with enough speed to get you air. Just as your wheels go past the top of the ramp, lean back as hard as you can. Spot your landing and roll away. This will take a lot of practice. Basically just try not to land on your head.
360 Grab: I do these either with a frontside 360 indy or a backside 360 Japan air. Just do a 360 and bring your knees up towards you then grab the board in the desired position. Make sure you can still get enough rotation, though, as under-rotating is a common problem with this trick.
Frontflip: I can't do these, but if you can, please email me and give me some advice. I'll then put it on this website so others can see it.
720: Same thing as frontflips. I'm no help, then again neither is anyone on the internet. So please email me if you know how to do these tricks!
Fire Jump: This isn't so much a trick as it is a stunt, but I can give you some tips. The first tip is to go fast. If you land in the fire and you're moving fast enough, you'll get out of it before it burns you. The second tip is to make a big enough ramp (or a little enough fire). That's pretty much it. Oh and don't freak out because you might mess up and fall into the fire.
