When developing the Four-Star 40, we had two main design goals:

First of course was impeccable flight performance, including the ability to perform any aerobatic whoop-dee-doo you can throw at it.
Second, it had to be ultra-simple to build without looking like a "box with wing".

We think you'll agree that the Four-Star 40 exceeds expectations on both scores and deserves a rating! Also check out the Four-Star 60 and the Four-Star 120
