Dette helikopter-programmet er kanskje det mest fleksible vi har å tilby i NNM i år (bortsett fra freestyle). Piloten velger fem øvelser fra listen under som hver blir poengtert fra 0 - 10. Øvelsene er hentet fra FAIs F3C-Freestyle F3N. K-faktor er gitt i parentes.

Piloten velger selv hvilken rekkefølge øvelsene skal utføres i, men denne må oppgis på forhånd og følges i samtlige omganger. Forøvrig gjelder regler for annonsering og tidsbruk som for Vingtreff.

Double roll backwards (7,5)

Model enters in upright backward flight and executes two consecutive axial rolls.

360°-turn with roll (8)

Rolling circle (8,5)

Model executes a horizontal circle while it performs consecutive axial rolls. Model speed, rolling rate and the radius of the circle should be constant.

4-point roll backwards (9)

Inverted pirouetting circle (9)

Model enters in inverted flight and executes a horizontal circle while it performs consecutive pirouettes. Model speed, pirouetting rate and the radius of the circle should be constant.

Pirouetting flip (9,5)

Model hovers or moves slowly and then starts pirouetting. At the same time or after one pirouette the model starts to flip but continues to perform pirouettes. There should be at least one pirouette during the 360°-flip (2 pirouettes are shown in the drawing). Both rotation should have a constant rate and the model maintains its position during the manoeuvre.

Cuban eight backwards (9,5)

Model enters in upright backward flight and executes a 5/8 inside loop to a 45°-descent. It performs a half roll, followed by a 3/4 inside loop and another half roll in 45°.descent. Model then finishes the first partial loop to upright backward flight. The tail of the model always points in the flight direction.

Outside loop sideways (9,5)

Model enters in lateral upright flight and performs an outside loop. During the manoeuvre the longitudinal axis is always vertical to the flight path.

Circle with flips (10)

The model executes a horizontal circle while it rotates about its lateral axis and stops shortly in each vertical position. The manoeuvre can be described as a series of 0°-turns, connected by half loops on a circular path. The radii of the loops should be equal and all stops should reach the same altitude. Also the circle should be round and not polygonal.

Inverted autorotation (10)

Model enters in an altitude of at least 30 metres in inverted flight. The engine stops or is running on an idle and the model descends in the inverted auto rotation state for about 5 seconds. Then it is brought to upright position, either by a half roll or a flip and descends to a smooth landing on the helipad.

Rolling circle backwards (10)

Model enters in backward flight and executes a horizontal circle while it performs consecutive axial rolls. Model speed, rolling rate and the radius of the circle should be constant and the tail of the model always points in the flight direction.

Pirouetting loop (10)

Model enters in upright flight and starts performing pirouettes. Then it executes an inside loop while constantly rotating about the yaw axis. During the loop there have to be at least 2, max 6 pirouettes. The pirouettes should be distributed equal on the loop.

TicToc (Metronome) (9)

Model hovers or moves slowly and is brought to vertical position (Nose up). It maintains its position by rotating alternately about the lateral axis for about 45° in each direction. Both 45°-positions have to be reached at least three times. The tailrotor stays almost in the same position during the manoeuvre.
