I am more interested in clean, straight line's for IMAC type flying. I plan on performing some 3d but nothing hair raising, just some flat spins, hovering, waterfalls, etc. But like I said before, I like to fly long vertical lines, that are straight and true. Would you recoment the Extra or the Edge.
What the other guy said.
The straight leading Edge of the Edge does not yaw dampen as well as a swept LE, so an Extra is inherently more stable in straight lines. The Edge slows down easier because it has a bit more drag and its stall characteristics are a bit different.
For pattern work I like the Extra Special. For pure 3d probably the Edge. For a combination I like the 300L.
