I'll try to answer what I can......
How long do uplines have to be?
Your upline can be as long as you wish. But you need to center your upline manuever. i.e. 1/2 cuban needs the roll centered on the 45* upline. Most folks count.....start your upline...count 1000 and 1 , 1000 and 2, roll.....1000 and 1, 1000 and 2, pull.
Also on most manuevers your downline needs to be the same length as the upline(and the rolls there are the same as the upline, just depends on the move.....but a good example is the Humpty Bump. Your upline and down line should put you at the same altitude you started.
This gives you a good starting point. It really depends on what move is next. Do you have a spin and need to be high? maybe increase to a 3 count. Also see box below.
What is the box?
The box used to be an undrawn line from end of the runway on each side out a specific distance. Thus you would need to stay within the bounds of the box. This means not to far out or in...and not too far left or right. There was also a top to the box if I'm correct. IMAC has gone to the zoneless box. basically 100yds out from the runway is a good distance....maybe closer if your plane is small or farther away if your plane is large. You want to give the judges a good view of your plane without scaring them from being close in or making them squint from too far away. As for left and right of the runway......similar there.
Anyone else have a better explanation?
Do you exit every manuever at the same altitude?
Yes, and no. A loop should be, but some manuevers won't. You really need to get into the rule book to understand. If your in doubt ask others on a specific manuver.
Where the manuevers are positioned on the sheet does that have any relevance as to what side of the box to do them in?
Again yes and no. You do not have to center any maneuvers.....but, good presentation calls for those on the right side of the card to be on the right and centered manuevers to be close to the center. What you are really looking for is good flow between manuvers.
How do i judge a 45* line?
Now your getting to the fun part......what's a 45* line? Since you have a caller.....get a triangle that is 45* or cut one out. Have your caller sit behind you and hold the card up in the sky at your start point. Pull up and fly what you think is 45*. Have the caller call out....shallow or steep. Repeat, Repeat, Repeat, Repeat, Repeat....did I say repeat? Eventually your mind will remember what a 45 looks like. That's how the judges know, from their own reptition.
The proper entrance into a spin?
This has been debated on all the sites........I'm not gonna touch this one other than to say this (and it may not be entirely correct)
.
Fly at idle and slowly give it up elevator. KEEP WINGS LEVEL, and crab into the wind the best you can. Eventually you will end up with full up elevator and the nose will drop....then add rudder for the spin.....if done correctly you can pick the direction of the spin with rudder. If your wings aren't level, then your wings have picked the direction
Also, red dashed lines.... This means inverted, yes?
Yes and no.........it does mean negative G's. But you don't have to be inverted for that to happen. If you fly a half square (like in the sportsman sequence) ......you fly straight and level then push to a straight down line (that is red dashed), your not inverted but you pushed negative G's to get there. Or a red triangle means negative snap.
Hope this was helpful. And if I made any mistakes.......sorry
