Another similar airplane I had built many years ago was the Air Hare which was a model class project for a couple of students, proportions were very similar and so are the flight characteristics. It is too bad the Air Hare kit is no longer available as that was a laser-cut kit. Both airplanes have fairly long fuselages which I think contributes to the pitch stability.

Last evening was the first flights for the AMA Maxi Jr and it flew absolutely perfect from the first flight with absolutely no trim adjustments needed at all. Power is a single loop of 3/16” Super Sport Tan rubber which appears to be adequate power for a steady climb. Unlike many smaller sport rubber models when the rubber runs out it glides fairly well and doesn’t go into a spiral dive.
From what I have heard from other people, everyone has thought this simple plane flies amazingly well.
