Hey jumah,

It's great to have you here!!

I will give you a very simple answer, others will elaborate further.

3D flying is done with the wings in a stalled condition, meaning that the plane isn't flying with forward motion, it's flying off the prop wash. You will see a lot of video's of birds doing some awesome aerobatics, but not necessarily in a stalled condition, that would be Freestyle aerobatics. Now for IMAC, that is flying particular maneuvers in a particular sequence, and if you attend a contest, you will be judged in your expertise in flying those maneuvers. In other words, it's Scale Aerobatics, or Precision Aerobatics flown with Scale airplanes.

This is the simple answer, it is more elaborate than this, however I will let others provide the particulars.

Check out some of the videos on the site, great stuff!!!

Welcome to the Giants!!!
