distance standing IMAC

[krayzc]

I have joined a new field and its has a large enough area that will allow me to practice IMAC. Can you all give me an est. on flying the moves that are on the left and right of my center. I need to figure out were I will be standing on the flight line to accomplish this. Meaning do I fly out on the average of being able to see the plane of course 300 feet to the left and then do a center move then 300 feet to the right of me with the plane being in front of me about 100 feet. That is the kind of scoop I need right now even if there are no guidelines. This is my 1st post in the IMAC so trust me I will read a lot of these posts over the next few weeks.

tks

Ok.....so here's the deal.

Hardly ever will you stand in the center of the flight line during a contest. Usually you'll see 2 lines running so you'll be offset to the left or right of the flight line.

Right now IMAC is a zoneless box with no moves that have to be centered or at the left or right of the box. Does it look better and score better if you do center, left, right manuevers.....I'd say YES. ACS is the new no box, box score to keep the footprint of IMAC down but the K-factor is so low I'd be more worried about the individual manuevers first.

There is no magic feet distance left or right of center. It depends on judges and the size of your plane. But try to keep your distance left to right equal. And give yourself enough time between moves to setup but keep your droning straight and level to a min (more chance for deductions).

Its a fine line we all dance.

Gerald,
Have you read the Rules and Regulations? This should answer your questions. Good luck!

Actually the center of the box is center of the judges not the center of the flight line or runway, so if there's two flight lines there's two boxes if you know what I mean.

NO Boxes! you can offset a center manuever due to the sun etc without being penalized.

It will look better right in front of the judgea and an inexperenced judge may give you a higher score for centering it, but technically there is no boxes!!

There's no center and has not been for a few years. I guess what I'm trying to say is that even when there was centering it would be center of judges unless you would offset the box in which case the pilot would have to notify the judges his intentions before the flight.

thanks all i will get to reading on that link tomorrow....

Gerald, is there anyone else in your area that flies Imac that you can practice with?

Sorry I wasn't as clear..........The center of the box that doesn't exist should be equal with your own body which should be centered between the judges but infront of them. Don't use the runway to determine the center since you will most likely not fly from the center of it but offset due to 2 flight lines running.

And yes you still get scored on the Box.....its called ACS. How well you use the airspace.......another name but a score to help keep you inside a unspecified box. Like I said earlier.....keep your sequence symetrical.....in that moves on the left are offset from your center 200 ft and moves on the right are the same and you'll be fine. Offset for the sun if you need to.......

But overall.........don't worry about that portion of your flight as much as each individual manuever and HAVE FUN!!!

One of the factors that got me interested in IMAC way back when was that a "box" did exit - that box was about 1000' left, 1000' right and 1000' back. There was no height limit other than "no greater than 60 degrees". Now of course, there is no official box. However, in measuring with a tape measure and having a flyer fly a 35% plane from end to end and back to back of that "box", it was more than very apparent to me and the others involved in this measurement, that at a 1000' the airplane looked like it was off the end on your antenna!

So get used to a comfortable distance where you can see your plane and have enough space to not rush your maneuvors, have room to do all of the specified maneuvors SAFELY and yet not draw too long of line between each maneuvor.

good deal

I am hooping to find someone in the area to start working with. on the weekend i can go to other spots to find someone if needed.

Gerald, where do you fly? Several of us IMAC wanabees fly at Waymer Field in Huntersville. There seems to be some IMAC interest in the Charlotte area.

Correct me if I'm wrong:
After reading the link provided in the third post the following would NOT be legal for any imac contest.

-turboprops
-a 4 motor (old hacker) setup on a planetary gearbox to one prop

Why would they exclude these? Why not specify one PROP, and not worry about how you are powering it as long as it meets the sound regulations. Hate to be someone who just dropped $X000 on a quad motor electric only to show up at a contest and be told its illegal!

Do they enforce this?

[Edge 540]

For example.... any scale turbine toucan or turbo raven would have to be fitted with gass or its not legal? It doesnt get any more scale than that!

Gerald,

I am flying basic this year and the following has helped me.

Fly the plane out enough to where you can see it well, but not so close that you are buzzing the runway during your passes. You should not be breaking your neck to see your plane in the loop.

I practiced the center maneuvers (loops, tear drop) in front of me, which at a contest would be the center of the box. The most important thing I've learned is to be consistent.

Read this if you haven't already.
