2008 Sportsman Narrative
Here is my version of the 08 Sportsman narrative. Feel free to correct me. I could not think of the name for figure nine so if someone will remind me I'll correct it. Once I have the corrections. I'll place it into a PDF file and post a link to it
2008 Sportsman Sequence Narrative
This narrative assumes flying left to right. All lines that have an element on them, such as a roll or snap assume that you are doing that element, centered on that line.
1.) Bowtie: Just before center, pull up into a 45 degree upline, once the line is established, perform 2 points of a 4 point roll which will place you inverted, continue to climb a short distance and pull to a vertical downline. Fly a short distance straight down and pull to a 45 degree upline, perform a half roll on this line which puts you inverted again and pull to level. You will now be flying to the left side of the field.
2.) Split “S”: You are starting this inverted so just pull a nice round half loop and as soon as you come level perform a half roll to inverted. Be sure not to draw a line before the roll. You are now heading back to the right.
3.) Loop, ½ outside, 1/2 inside: This is best done right in the middle. Start pushing into a nice gentle outside loop just before center, once you get near the top start a one half roll, for the best score, you want to be halfway through the half roll at the very top (IE, knife edge as you go through the top), on the backside of the loop you are now upright so just complete the loop and exit upright. For the best score. stop the loop at the same altitude and point in the sky as when you started the outside portion of the loop and make the radius the same for both sides of the loop, you are still flying to the right.
4.) Hammerhead: Begin this figure by applying full throttle and executing a gentle pull to a vertical upline. Once you have reached sufficient altitude, begin to decrease the power. Leave 3 or 4 clicks of power on, and just before the plane stops moving, apply full rudder. It is almost always easiest to hammer INTO the wind if there is a cross-wind. If the wind is down the runway, hammering either left or right is OK. Once the plane starts to pivot, the throttle can be reduced to idle. One method of preventing the plane from wagging its tail after the pivot is to keep some rudder input after the pivot and slowly take it out as the plane goes down. At the bottom of the line, execute a gentle pull to a horizontal exit and increase the throttle. Try to make the entry radius and exit radius equal don’t execute a sharp pull at the bottom. You should now be flying back to the center of the runway. You are now heading to the left side of the field.
5.) Cross-box Humpty Bump: This figure gives you the option of either bringing the airplane in closer to you or moving it farther out. It will probably present better to the judges if you take this figure out, but if you are finding yourself way out before you start this figure, bring it in. I will describe this figure going OUT. Just prior to the center of the box, increase power to full, and complete a gentle pull to a vertical upline. Insure that this line is vertical before doing any rolling or you will be fighting the line all the way up. Hold the line; execute a Âľ roll to the right. You will now be looking at the top of the airplane. Begin a gentle push for a half outside loop across the top. Reduce power to idle as you pass over the top and check to insure your wings are level to make the downline nice and straight. Complete 2 points of an 8 point roll to the left and hold that line to make the line segments equal in length. Finally, execute a gentle pull to horizontal, level flight while gradually increasing power. You are still flying to the left.
6.) Sharks Tooth: Fly towards the end of the field, and increase power to full throttle. Execute a gentle pull to a vertical upline. As before, use the rudder to maintain a nice vertical track. Execute a half roll in the center of this line. Execute a gentle push across the top of the figure to an upright 45 degree downline coming back towards yourself and decrease the power to idle. Perform one positive snap, I like to blip the throttle during the snap to help keep me online coming out of the snap. Come all the way to idle and finish the 45 degree line, pull to exit upright and horizontal. You are now coming back to the right.
7.) Teardrop: Fly all the way down to the right side, being sure to keep your altitude perfectly level and go to full power and pull to a vertical upline, execute, on the center of this upline, a half roll. Pull a 5/8th loop to a 45 degree downline, perform one full roll on the downline, pull to exit upright and horizontal. You are now heading back to the left.
8.) Vertical Upline: Fly all the way down to the left side, being sure to keep your altitude perfectly level and go to full power then pull to a vertical upline. Execute 2 points of a 4 point roll on the center of this line, push to exit upright and horizontal.You are heading back to the right.
9.) Figure Nine from the Top: As you approach the center of the field at a high altitude, begin to reduce the throttle smoothly. As the plane slows, you will have to feed in up elevator to keep it from descending. This will gradually bring the nose up. Once the throttle has reached idle, keep feeding in up elevator until the nose drops in a stall. You will also have to be keeping the line straight with rudder – particularly if there is any crosswind and your airspeed decreases. Don’t worry if the nose of the plane is cocked 45 degrees before the stall – it is most important to keep the line straight! As the nose drops, feed in rudder in the same direction as the wing that is falling – right rudder if the right wing is falling and left rudder if the left wing is falling. Once the spin begins, go to full rudder and full aileron in the same direction (you should already be at full up elevator). After 1.5 turns, neutralize all controls to stop the spin. If the nose is high, give down elevator to establish a vertical downline. Hold the downline for a moment, and then begin a gentle pull for the 3/4 inside loop. As you pass through the bottom of the loop, smoothly increase power to full and once you reach the horizontal and are inverted, hold that line. You should be giving some down elevator to hold the line. Hold the line for the next maneuver. You are heading to the right.
10.) Inverted 180 Aerobatic turn: You have the option of doing this coming in or going out. This should depend on how much room you have if you want to bring it in. Remember, you have a deadline to consider which for most contests are 100 feet out from where you are. I will assume we are taking it out. From inverted, roll into a 60 to 90 degree banked angle then push to start the turn. Use the rudder and throttle as needed to keep altitude. For the best score, keep the bank angle constant as well as the altitude. When you complete the 180 degree turn, roll out level and inverted. Fly a short straight line while inverted, call yourself out of the box. It’s also important to use the same roll rate to roll out of the maneuver that you used when starting the maneuver.

RE: 2008 Sportsman Narrative
The IMAC website will in a short period of time have IMAC introduction narratives for Basic and Sportsman for those new to Scale Aerobatic competition. In the meantime thanks for writing these as they will help those who have not yet learned to read Aresti. Aresti is a very simple visual language that is far superior to any written sequence dialog and should be learned very early on in anybody’s IMAC experience.
That all being said there are a few comments about your narrative, first, figure one that some call a Bowtie or double sharks tooth, this is from Family One so all lines can be of different length and each radii do not need to match as well. That means the entry and exit altitude or the altitude of the top and bottom of the vertical line do not need to match anything. The key to Family One is that the lines are 45, 90, horizontal and any roll element is centered on that line.
Figure eight you call a “Half Square Loop” and many have used this name for this figure for years, but for us who teach judging it’s not the description we prefer. Half Square Loop suggests a set length of line for the entry and exit lines, and this is not so. What this figure really is just a “Vertical Upline” and this is how we describe this figure. I know this might seem a little picky, but it all has to do with the mindset a figure description suggests.
Figure 9 does not have a real strong “traditional” name, some call it just as you described or some might say a “Figure Nine from the Top”.
Thanks for taking the time to write these narratives and I hope everyone enjoys and learns something with the 2008 Knowns.

RE: 2008 Sportsman Narrative
And once again you can get two great references on how to read Aresti here:
[link=http://www.scaleaerobatics.org/PDFDOCS/ams.pdf]Aresti Made Simple[/link]
And
[link=http://www.scaleaerobatics.org/PDFDOCS/dict.pdf]Aresti Dictionary[/link]
Between these two documents you should be able to read Aresti in no time. Plus it is lots of fun!!
