Lets get back to the basics of this thread geometricaly speaking.
A line drawn in a plane and moved about in that plane will intersect with another draw line at a given point. If triangulation is used in a given manuver then there are essentially three lines that can be intersected at any given point. An intersection in a circle(loop)is know as a tangent and is less likely to happen unless of course its my airplane. AND thats how I midaired. Only a finite amount of space in the box and sooner or later those two objects moving about will collide. MURPHYS LAW
I for one dont want to slow a contest down so lets not get to the point of only one plane in the air at a time.
