Easystars are fun gliders that are very suitable as a beginner's plane.

However given that you'll have an instructor, get into the PTS as quickly as possible.

The instructor will prevent your PTS ending up in a trash heap, while teaching you to fly full aileron control planes.

That will give you more bang for the buck ( time ) on your lessons... and you can always fly the Easy Star when the instructor is not around, after your first few flights.
