I just got one of these on your recommendation micro. I saw the video you posted and it looked great, unfortunately the flight time seemed pretty short and it didn't fly anywhere near as good as yours. It has a strong tendency to turn to the right, even when I hold the rudder all the way to the left to counteract it. The instructions give advice on how to correct for this, but being new to planes and rc, I don't quite understand what they mean. They show lines on where to cut and in which direction that place should face, but once I cut along the lines, how do I keep those parts facing in the direction I want them to face?
