Legal Eagle Rules


THE INDOOR LEGAL EAGLE EVENT

Designing, building, and flying models to the simple rules for this event has proven popular with the members of the Miami Indoor Model Aircraft Association (MIAMA) for both experienced and novice flyers.

There are no minimum weight requirements. Instead, weight is controlled by requiring no wood can be used less than 1/16 " square (except for the prop).
Aircraft size is controlled by the plan having to fit on a sheet 8-1/2" x 14". Single side covering on flight surfaces is permitted and Jap tissue must be used with no thin film covering. No charisma judging is required and flight times determine the winner.

So the challenge becomes how to optimize the design to fit on the limited plan sheet size and build with the minimum number of 1/16" square sticks of the lightest balsa that you dare. The result is an aircraft that is easy and quick to build and is capable of good flight performance. In Florida, current designs are getting 5 minute flights in a 40 ft. ceiling.

Give it a try - it makes for a fun event.
