What is Max height: Definition and 124 Discussions

The Team Mini-Max Hi-MAX is a single-seat, high wing, strut-braced, single engine aircraft available in kit form for amateur construction. It first flew in 1987 and is a high wing development of the Mini-MAX, hence its model name.The Hi-MAX was originally produced by TEAM Incorporated of Bradyville, Tennessee. After that company was bankrupted by a lawsuit production passed to Ison Aircraft also of Bradyville, Tennessee and next to JDT Mini-MAX of Nappanee, Indiana. The company was renamed Team Mini-Max in 2012 and moved to Niles, Michigan.
