I'm kinda new to this, and I'd sure like to have someone explain what the new 2005 Basic #10 figure is doing. I'm just totally cluless as to what this item is supposed to look like.
Thanks.

I am no expert in IMAC but my plan is to compete next year. I believe #10 is an aerobatic turn which is bank 60 to 90 degrees and make the 180 degree turn without loss of altitude.
See if my IMAC study's have paid off.

Thanks Mat. I will practice the turn in that manner...it seems as though anything approaching knife-edge is what they want to see...maintaining altitude of course. It would appear from the sketch that the return line would be different than the outgoing line...and they aren't specifying the direction of the turn. I suppose away from the flight line would always be preferable.
Thanks for the tip.
Happy Holidays

I assume the direction of turn is pilots choice, not sure though. if you have been blown out you may want to decide to turn inboard but the line will not be the same offset by the radius of the turn.
Hope I am on the money.

Good luck, I need to get some sim time on this one and the sportsman, but have been busy building.

Hey guys,

You can get to the imac site ( http://www.mini-iac.com/ ) and download the Flying and Judging Guide. There is a section there on how to judge
aerobatic turns. That will give you all the information you need.


Stratos.-

You can also download 2 reference sources for reading Aresti on the main page of the IMAC site, directly under the link to get the sequences.

This figure is a Family 2 Aerobatic Turn. The criteria is to establish and maintain a bank angle no less than 60 degrees and no more than 90. The angle must be held constant. You do not get more points for a higher bank angle (90 versus 60). But it must stay constant, the turn must finish at the same altitude it started at, and you must finish with the track of the plane 180 degrees opposite to the entry.

The IMAC site has a very good descrpition on how to fly the Basic sequence, also immediately below the links for the sequences.

For some reason the description for flying the basic sequence will not open for me. I see to get to the sportsman. I will give it a try later see if I can get to it.

Thanks for the information.
Mat

Yes, I also found that the basic would not open. I too will try it later.

The link was broken. The IMAC Webmaster has it fixed now.

capt:

in literal aresit-ease, the direction of any cross box figure is at the pilot's option. however, that is for full scale, and that sometimes doesn't work for toys, as evidenced by the 180 degree roller in advanced. the direction of cross box exit is often announced at the pilots' meeting, and no sane CD wants an airplane turning into the flightline. it is a good question for a pilot's meeting if it has not been previously addressed. as for the execution, read aresti's description carefully because a knife edge turn is within the rules. it looks goofy but it cannot be downgraded for excessive bank angle. what the judges want to see is an established bank angle, constant radius, and constant altitude. all that being said, it is a very low k figure and it there is very little reward in doing one well.
