RE: IMAC "BOX" SIZE
Thank you for responding.
IMAC is going to go through a couple of changes when we move to follow the FAI guidelines. FAI is an international organization as you know from the F30 pattern side of the house. It may take a couple of more years but expect to see a 75 degree box and centering of maneuvors to come back. The 60 degree angle thing is going to have to change as well. If you calculate the back side of a plane flying at a height of 60 degrees it is over 2200 ft away linearly - that is a fur piece away.
Stay tuned and if you haven't attended an IMAC judging seminar please attend the next one in your region - you'll learn a lot.
