Are you kidding? Then why does it explain how in the manual? The question I had on t he same topic is when you do mix 2 and 7, the trim for elevator only moves one elevator half causing the plane to pitch, roll, a little when applying up or down elevator. I love the radio other than that...I had a Futaba super 8 which had the alieavator function for split elevators so you dont have to use a servo reversor or turn the linkage opposite which induces elevator differential in the two halfs. If you cant mix dual elevator servos with the Eclipse than I would call that a "Big" design flaw as most large planes all have split elevators. Thanks
