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.

1. Drawing must fit on one side of one sheet of legal size (8-1/2" x 14") paper.
2. No component parts drawing may be superimposed or overlap another and
must clear one another and the edge of the paper by at least 1/8 inch.
3. Wing(s) and stabilizer must be drawn full span, tip to tip and fuselage drawn in its full length from nose through tail in one piece.
4. Fin(s) may be drawn where space allows and not necessarily attached to the side view.
5. Landing gear must be drawn in its place on the side view showing its full length.
6. No top or front view is required.
7. Drawing must be presented to C.D. on demand.
1. Smallest wood size to be 1/16 inch square except for propeller.
2. Fuselage measured to its outside surface must contain a space 1" x 1.5" x 3".
3. Fuselage must have a cabin or open cockpit with a raised windshield of at least 30 degrees of clear or translucent material. Cockpit must be actually open, with a headrest or canopy.
4. Flight surfaces; Leading and trailing edges cannot parallel each other.
5. Tip outlines must have no straight lines except for stabilizer where a twin fin is used.
6. If twin fins, or two wings are used in the design, parts may be built in duplicate over the same drawing.
7. Jap tissue required on all non-sheeted, open framework surfaces except for fuselage surfaces covered by a flying surface directly attached to the fuselage and areas involved in an open cockpit or minimum access area to the motor. No ultra light film covering to be used, unless used for windshield or windows. Flight surfaces may be single or double covered.
8. Landing gear must use at least one 1 inch diameter wood wheel.
9. Use of motor stick(s) or tube(s) O.K. and if used, must be shown on the side view in one continuous length in the proper position.
1. Models must R.O.G. from floor or any solid place designated by C.D. on contest day.
2. Total of best 3 flights out of 5 wins and delay timing of 20 seconds with two delays in succession as one official, per AMA rules.
