Hi Frosty,
I have just started snowboarding and i'm beggining to improve dramatically but....
I still can't go down the hill heel side. Everytime I try going on my heel side I end up on my butt.
I even have to flip my board over to the toe side when I wipe out just to get up.
How can I correct this?

Sure bro, we can get you going on the heelside.  Can you provide a little more detail as to what you gather happens that causes you to fall on your butt?  Also, what kind of gear (board, boots, bindings) are you using?

I have a GNU Carbon High Beam Series Snowboard, 24/7 V3 Bindings and a pair of Fresh snowboard boots. Whenever I try to slow myself down or go too fast heelside I fall. I guess it's just a balance issue. When im heelside is there any particular place where you are supposed to apply your weight to stay balanced better?

(also)Try using your front  foot to initiate the turn (give it some flex) and don't lean too far. 
If all you do is lean back with your upper body you will fall.
imoo

Welcome to the forums mtnplummeter and thanks for the great advice!

Good question man...  REALLY good.  OK, here's the scoop.  What your friends say is true to a certain degree and only to a certain degree.  Let's say 10% of doing freestyle is the specific gear you have.  MOST of it is your own skills and level of confidence you have.  Do not transfer responsibility to your gear.  Seems like you have really nice stuff.  I have been riding for over 17 years and rails always frighten me.  If I am really ON a certain day i might do them, but if any seed of doubt exists in my style I pass em up.  If some jerk wants to criticize me for it then forget him, I stay healthy enough to ride another day.  Doing rails WILL screw up your board after some time and you will most likely get really hurt when wrecking on one of them.  That's just the way it is.  Use your head and go for what you know.  Gear is only a small fraction of doing freestyle.

im one of the people that agrees with having a set up dedicated for boxes, rails, etc.
i ride the terrain park with a forum manual thats shorter and has more flex than my
all mountain board. the flex of the manual is a 3, i can bend it to great degree with my
arms. it borders on the "wet noodle" definition of a jiblet. also it has a p-tex base that
i can repair on the mountain if i have to. but i also agree that its the riders ability and
not the equipment.

a good way to learn rail tricks flat land is on a balance board. a great way to get one of those
is to either buy a skateboard deck, or hopefully you have one laying around in the garage
somewhere. take the trucks off and place the board on a 2 liter bottle of soda. its best
to take the soda out though and replace it with water, just incase it explodes.
standing on the board balanced with tip and tail off the ground directly in the middle of
the soda bottle will help you find your balance point for boardslides.

heelside carves still are hard for me after 12 years of riding. some things just dont come to
you. i can make easy heelside turns but nothing as far as a hard carve. i just slide. i got
sick of wasting money taking lessons from people and decided to figure out my own way
around it and worked hard on 180 flat spins. but i have alot of quirks about riding. frontside
airs and spins are really really hard for me...the most i can do frontside is a 3. backsides
are completely natural to me, the season on the east coast started late and im already back
to b/s 5's and plan on starting to learn b/s 7's by the end of the season.
i guess what im trying to say with that paragraph is, if things refuse to come to you, figure out
a way around them. just concentrate on having fun. thats what this sport is all about

Best thing I've ever found on the internet Frosty! 

I can send pictures if you need to see the setup.

OK, I'm ready to take some heat for this suggestion, but try using ski poles the first few times out.  You may look a little goofy (at my age, who cares), but you'll spend a lot less time sitting on the ground nursing sore body parts.  The poles will also:
1.   make stepping into your back binding much easier (no sitting required);
2.   make getting up easier when you do fall; and
3.   allow you to keep upright when you catch a toe or heel while going slow!

For skiers, the transition to life as a boarder will be much easier with two old friends (poles!) by your sides.  Poles will also help newbies without ski experience to avoid much pain after the first day out.  It's your call, poles or pain? Poles will make your first few attempts at snowboarding alot less painful and more fun.  Give it a try!
