In my humble and unimportant opinion, IMAC is handcuffed by the archaic notion that their planes ought to only be doing the maneuvers
that real IAC planes do..... this was a founding concept of the genre.... but RC has sooooo outpaced full size planes.... IMHO...
that rigid constraint ought to be eliminated.....

the sequence of maneuvers ought to include whatever an RC plane can do .... example... Rolling Loops....
1 1/2 snaps from KE to KE..... not to mention judging criteria could be established for most of the
"3D" maneuvers.....

I will tip my hat to the pattern guys... they have more difficult and interesting sequences.... they don't
seem to rely upon more and more snaps as a means to distinguish the different classes....

boy.. I am gonna catch heat over this!!
