Definitely a maintenance issue. They are spot on when they leave the factory but will need adjustment over the the next 250-300 hours as everything beds in.
it's not a difficult job to adjust the but it's not a 15 minute job either. Flight schools are often reluctant to take what they see as a serviceable machine out of service.
The cyclic trim does take a little time to master. It does vary with speed and power and also needs quite a bit of re trimming in the first 10 minutes of flight until all the elastomeric bearings warm up. After a while you do it automatically.
