Takeoff and level flight:
A correct takeoff consists of the model rolling smoothly along the ground for a distance of not less than 15 feet but not greater than one-quarter of a lap. The model then rises smoothly into the air with a gradual climb and a smooth leveloff to normal flight level (approximately 5 feet) over the point at which the model began its ground roll. The model continues on for two smooth laps of normal level flight to the point of original leveloff.
Reverse Wingovers (one required):
Correct reverse wingovers are judged when the model starts from normal flight level, makes a vertical climb and dive, passing directly over the flyer's head, cutting the ground circle in half, and recovers in an inverted position at normal flight level. The model then continues for half a lap inverted to the starting point, and again makes a vertical climb and dive over the center of the circle from inverted flight, before recovering upright at normal flight level.
Errors:
Consecutive Inside Loops (Three Required):
Correct loops are judged when the model starts from normal flight level and makes a series of three smooth, round loops, all in the same place with the bottoms of the loops at normal flight level and the tops of the loops with the lines at 45 degrees elevation. The model then continues for another half loop, recovering inverted and descending to normal flight level, flying two laps before being judged for inverted flight.
Inverted Flight (two laps):
Correct inverted flight is judged when the model makes two smooth, stable laps at normal flight level.
Consecutive Outside Loops (Three Required):
Correct loops are judged when the model starts from the inverted position at normal flight level and makes a series of three smooth, round loops, all in the same place, with the bottoms of the loops at normal flight level and the tops of the loops with the lines at 45 degrees. The model then continues for another half loop, recovering at normal flight level.
Consecutive Inside Square Loops (Two Required):
Consecutive inside square loops are judged correct when the model starts from normal flight level and flies a square course consisting of two loops, each with four inside turns of approximately 1.5 meters (4.9 feet) radius and straight equal sized segments, with bottom segments at normal flight level and top segments as inverted level flight at 45 degrees line elevation. The two bottom corners are equal and so are the two top corners. The maneuver begins and ends with the model in level flight at the point of start of the first turn.
Consecutive Outside Square Loops (Two Required):
Consecutive outside square loops are judged correct when the model starts from level flight at a 45 degrees elevation and flies a square course (starting with a vertical dive) consisting of two loops, each with four outside turns of approximately 1.5 meter (4.9 feet) radius and straight equal sized segments with bottom segments flown inverted at normal flight level and top segments as level flight at 45 degrees elevation. The two bottom corners are equal and so are the two top corners. The maneuver begins and ends with the model in level flight at the point of start of the first turn. The model recovers into normal level flight.
Consecutive Inside Triangular Loops (Two Required):
Correct triangular loops are judged when the model starts from normal level flight and flies a triangular course, starting at the base turn. The three sides of equal length and the three corner angles of equal size. The top corner must be placed at 45 degrees elevation. The second triangular loop must be flown in the same flight path as the first one. All corners must be smooth, precise, and of approximately 1.5 meters (4.9 feet) radius.
Horizontal Eights (Two Required):
Horizontal eights are to be entered and completed at the intersection point of the circles and exit at the same point. The inside loop must be flown first. Correct eights are judged when the model makes two eights, each consisting of two round circles or loops of the same size, tangent to each other, and in a horizontal line. The model must enter the eight from normal flight level and be vertical at the intersection point of tangency of the circles. The eights must be symmetrical. At the top of each circle the model must be at the 45 degree elevation point; the bottoms of the circles must be at normal flight level.

Square Horizontal Eights (Two Required):
The eight is to be entered in the direction of the climbing sides of the loops, and after completion of two eights the exit is made in the same direction. The inside loop must be flown first. Correct eights are judged when the model starts a vertical climb and makes a modified inside square loop followed by a modified outside square loop ending with a vertical climb at the same point. The loops are modified so their climbing sides are vertical, and the loops are tangent to each other along these sides, and the turns starting and ending the climbs are 90 degrees. The top sides are slightly shorter than the remaining sides which are of equal length. The maneuver is repeated to form two eights. Tops of loops must be at 45 degrees elevation, bottom of loops must be at normal flight level, and all turns must be smooth, precise and of approximately 1.5 meters (4.9 feet) radius.
Vertical Eights (Two Required):
Vertical eights are to be started at the point of 45 degrees elevation and finished at the same point in inverted flight. The inside loop must be flown first. Correct eights are judged when the model makes two eights, each consisting of two round circles or loops of the same size, tangent to each other, and in a vertical line. The model must be horizontal at the intersection point of tangency of the circles. The eights must be symmetrical, the top of the heights at a point 90 degrees over the flyer's head, and the bottom of the eights at normal flight level.
Hourglass Figure (One Required):
The correct hourglass figure is judged when the model starts from normal flight level and flies an hourglass course starting with an abrupt turn followed by an inverted climb, turns into a wingover path across the circle center for a distance equal to half the total climb, turns into an inverted dive, and recovers at normal flight level. The flight paths of the climb and the dive cross at 45 degrees elevation. The four rounded corners of the figure shall have a radius of approximately 1.5 meters (4.9 feet) and the flight path forms two equilateral triangles of equal size, turned peak to peak, and one in vertical line above the other.
Overhead Figure Eights (Two Required):
Overhead eights are to be entered and completed at the intersection point of the circles, directly over the flyer's head, and exited from the same point. The inside loop must be flown first. Correct overhead eights are judged when the model makes two eights, each consisting of two round circles of the same size, with the intersection or point of tangency directly over the flyer's head. The model must enter the eights with a vertical climb through the center of the circle, and must always point in this direction at the center of the eights. The eights must be symmetrical and the model at the lowest point of each circle must be at a point of 45 degrees elevation.
Four-leaf Clover (One Required):
The maneuver is entered from level flight at approximately 38 degrees elevation and consists of one full inside loop, level flight, three-fourths of an outside loop, vertical climb, three fourths of an outside loop, level inverted flight, three-fourths of an inside loop, and a vertical climb. The right loops are tangent to the left loops along a vertical plane of symmetry through the center of the clover leaf, and the bottom loops are tangent at the top loops. The loops are of equal size and they are connected by horizontal and vertical flight paths. The bottom points of the maneuver shall be at the 1.5 meters (4.9 feet) height, and the top shall be tangent to the vertical plane through the circle center. When the last loop is performed, the maneuver is made complete by a vertical climb through the center of the four-leaf clover. (Exit the maneuver over the top of the circle into the wind, returning to normal level upright flight on the other side of the circle.)
Landing:
A correct landing is judged when the model descends to land with no bounce or unusual roughness, and without any part of the model other than the landing gear having touched the ground. (In the US pattern there is no requirement for the plane to travel any particular distance before landing, nor is there any prescribed point at which touch down must be made after descent starts or the engine quits.) Main wheel(s) or three-point landings are permissible.
