Perfect! Very strong and sturdy mounting system. RAM gear is amazingly functional and this arm is no exception. Perfect length to mount the iPad holder to the yoke clamp, or any other mount/clamp. The shorter one can foul the controls and the longer one places the iPad to close to the pilot. This is the best length imo.
