I don't think you can enter a Cub, Beaver, or Cessna 150 in an IMAC event. Simply because these arent aerobatic planes and have never been used to compete in an IAC event. You could enter one of these planes in the basic class, because that class doesn't require a scale aerobatic plane. It's a "get your feet wet" class and should welcome anyone with a Kadet LT-40 if they want to try it out.
Cubs have been used a lot in IAC. In fact, Giles Henderson dominated Sportsman with a clipped-wing Cub and won the Nationals at least once with it. A Cub will be difficult to be competitive with in IMAC, but it's legal
