Sparky,
Call the AMA or go to their website and ask for an AMA rulebook. They will mail you one free of charge if you are an AMA member. www.modelaircraft.org . The book has EVERYTHING you need to know about pattern, scale and everything else AMA sanctions competition for.
It includes the sequence of maneuvers for each level in pattern and it has a picture and description of each maneuver it even tells you what NOT to do in the form of downgrade descriptions.

Also if you are serious about Pattern there is an organization The National Society For Radio Controlled Aerobatic www.nsrca.org that has all of the sequences in a printable form that includes the K Factors(difficulty factor). The lists of manuevers are called "Schedules". They are under one of the tabs on the left side of the screen.. They have a monthly magazine that comes with the subscription and its the best way to find out about contests in your district and meet other pattern flyers in your area.

Heres the basic idea of pattern

Pattern is performed in a virtual box.
A pattern field will have a flight box for you to stand at,, ther will be 3 lines in front of you on the ground starting at your feet. One extending out on the runway straight out from you. Then there are 2 lines extending out at 60 degrees infinitely that start at your feet and go out diagonally across the runway and into eternity in opposite directions. The back of the box is straight out in front of you about 175 meters (should be poles out there so you can see how far out you are. The sides of the box follow the diagonal lines on the ground so at your feet the box is about 1' wide and at the 175 meter mark out there its probably about 1000 meters wide,, you get the picture. The further out you fly the more room you have to fly. The best place to fly is probably about 125-150 meters out in front of you. You usually dont get downgraded for flying too high but technically the upper part of the box extends upward from your eye at a 60 degree angle. You will be hard pressed to fly too high if you are out at 125 or so meters..

You are scored on your takeoff and landing and almost every moment in between. You takeoff into the wind, turn around and make a downwind pass and then turnaround back into the wind to enter "the box". You should establish your distance out on the downwind pass so that you enter the box flying level and at the right distance out.

Vocally announce "enter the box" as you enter the box.
Announce each maneuver just before you execute it.

The 1st maneuver will be centered in front of you. The center of the maneuver should be right on the centerline at your feet. I hold my transmitter so that the antenna is pointed up and I can see it to help center my maneuvers.

The second maneuver will be at the upwind end of the box and is called a "turnaround maneuver" like a stall turn, 1/2 reverse cuban 8, 1/2 cuban 8. third maneuver on the center going downwind, turnaround maneuver on the downwind end back to another centered maneuver,,, you get the picture..

The turnaround maneuvers should be made in a timely manner so that they have the correct geometry, but at no time do you exit the box while performing the maneuver. You get downgraded for getting out of the box when you arent supposed to. Ideally the backside of a turnaround maneuver will be performed so that the backside of say a 1/2 cuban JUST touches the box line,, that gives you all the possible room you need to get level and lined up for your next centered maneuver.

Remember the box gets smaller the closer in you fly, so if you are right over the runway the box is only going to be about 100 meters long and have to do EVERYTHING inside the box,, so again mantain adequate distance away from you ,, so 125-150 meters and yo will have all the time you need..

Also between each maneuver there should be a straight line..

So say you do the 2 consecutive loops of the sportsman pattern. As you come out of the second loop you should level out for at least some distance before starting your turnaround maneuver.

So it should
enter the box,
straight line
centred maneuver
straight line
turnaround manuever
straight line
centered maneuver
straight line
turnaround maneuver

on so on and so forth...
