I am have a real problem with getting my Mosquito XEL MR to track smoothly. I do not have access to any track and balance equipment so I am trying things the old way. I have the MR blade pitch links set up for the correct negative angle per the manual. I use a digital level with reading to 0.1 degree. Then I used reflective tape on the blade ends and hovered so a helper with a bright light could see the tip path. I also have flown it and adjusted the PCL until it was as smooth as I could get it. It is pretty smooth in hover but has a real vertical bounce in forward flight. The more collective the bigger the bounce. My blades do not have bendable trim tabs. I have set the sweep of each blade to 0 degrees, so both are neutral. I have not messed with adjusting the sweep angle. Any new ideas would be helpful.
