Дополнение в манёврах F3N
B.1 Two Opposite Piro Funnels   K-factor 10.0
MA enters in inverted forward flight, performs a quarter pirouette and starts an inverted funnel with the tail pointing to the centre. When it crosses the centreline it enters a circle and starts pirouetting in a way, that after each quarter circle the fuselage has changed its direction 180° (e.g. model starts from right to left, after a quarter circle the tail points to the flight line, after a half circle away from centre, after 3 quarters to the flight line again and after the circle to centre again). After one circle the pirouetting direction is changed, and a second circle follows with the same conditions for the pirouette. After the second circle MA exits the manoeuvre in inverted forward flight.

B.2   Double O One   K-factor 10.0
MA enters in forward upright flight parallel to the flight line. Model performs ¼ of a loop. After the ¼ loop the boom is vertical, and model is on centre line. MA then performs one complete outside loop. During the first half of the loop, the model performs half pirouette, and during the second half of the loop, the model performs another half pirouette in opposite direction. MA is now back to same point on the centreline and with same orientation as when the complete loop started.
Model now performs a complete inside loop, with pirouettes similar to the first complete loop.
After second complete loop, MA continues vertical upwards, makes a slow half roll symmetrical to the stall point, and exits in backward inverted flight to the same side and height as the entry came from.

B.3 Piro Globe double reversed   K-factor 10.5
MA enters in upright flight and then performs four pirouetting loops. During each loop, the flight path is changed continually in a way, that the low point is passed rotated about 45° (seen from above) until a complete globe has been described.
After each loop the pirouetting direction is changed at the bottom of the loop. MA performs on every top of the loop a half roll in either direction while still performing pirouettes. The MA exits the manoeuvre at the same altitude but in opposite direction to the beginning. During each loop, the MA must perform at least two pirouettes.

B.4   Rolling circle reversal   K-factor 9.5
MA enters in forward flight and performs a horizontal circle while it performs axial rolls. The direction of rotation of the rolls must be changed after each quarter circle without hesitation between the rolls. MA speed, rolling rate and the radius of the circle should be constant.

B.5   Galaxy   K-factor 10.5
MA enters in upright flight, performs a quarter pirouette and starts a funnel with the tail pointing to the centre. During the funnel the radius of the circular flight path decreases and the declination of the rotor disc increases, so the path becomes a spiral. After 720° (2 spiral shaped “circles”) the declination should be about 60°. Then a smaller half funnel follows where the declination of the rotor disc becomes vertical when the model crosses the imaginary centre point of the funnel spiral. When MA crosses this point it performs a half pirouette and immediately continues with a small half nose down inverted funnel (the flight path has the shape of an S here when viewed from above), followed by two inverted funnels (the nose now pointing to the circle centre) with increasing radius (and decreasing declination of the rotor disc) and exits the manoeuvre in inverted flight in the same direction but in a different distance as the entry.
During the manoeuvre the height of the flight path must be changed symmetrical to the point where the model crosses the centre point, i.e. it may climb during the first 2 1/2 funnels and decline during the second 2 ½ by the same amount.

B.6   Cuban 8 with Roll Reversal.   K-factor 10.0
MA enters in upright backward flight. When crossing centreline it start continues rolls.
While rolling, MA performs half Cuban 8 parallel to the flight line.
Symmetrically around the centreline, MA stops rolls, performs half pushed elevator flip, and restarts rolling in opposite direction. MA is now in forward flight while rolling.
MA then performs second half of the Cuban 8 while continuously rolling.
Symmetrically around the centreline, MA stops rolls, performs half pushed elevator flip, and restarts rolling in same direction as was used at manoeuvre start.
MA stops rolling and exits in upright backward flight.

B.7   Vertical tic-toc eight.   K-factor 10.5
MA enters in upright forward flight and performs a quarter roll to knife edge tic-tocs. Model then performs a half tic-toc loop. On the top of the loop MA performs a half pirouette, and then continues up with another half tic-toc loop while keeping the tail in the flight direction. On top of this second circle MA performs a half roll. It completes the upper tic-toc loop with the tail in the flight direction. It then performs another half pirouette and completes the lower tic-toc loop with the nose in the flight direction. Model exists in upright forward flight
During the manoeuvre the longitudinal axis of the model always follows the flight path.

B.8   Funnel with half rolls and pirouettes K-factor 10.0
Model enters in inverted flight and performs a quarter pirouette before crossing centreline. Model then performs two superimposed horizontal circles with the rotor disk tilt at least 30 degree from a horizontal plane. After each half funnel (except the last) the model performs a half roll. On each half circle, model performs an integrated half pirouette. Direction of pirouette must change after each half roll. After two funnels (and three half rolls) the model exits in upright flight via a quarter pirouette. The diameter of the circles should be at least 10 metres.

B9   Four point Tic toc reversal   K-factor 9.0
MA hovers with the tail to the judges line and is brought to vertical position (Nose up) about 135°. It then starts rotating alternately about the lateral axis for about 45° in each direction. Both 45°-positions have to be reached one time (i.e. one tictoc) and then the MA performs a quarter pirouette in clockwise direction. It performs another complete tictoc in this position, then again performs another quarter pirouette in clockwise direction and so on. After the MA has performed a complete pirouette, the MA starts immediately a second 4-time tictoc in anti-clockwise direction. The MA maintains its position during the manoeuvre.

B.10   Duus Igloo   K-factor 10.0
MA is hovering upright nose in on centre line. Model then performs half pulled rainbow away from the pilot, while also doing an integrated half pirouette. At top of rainbow model makes sharp quarter aileron roll, and completes second half of the rainbow parallel with flight line while making another integrated half pirouette until model hovers inverted shortly, now with boom parallel to flight line. Same sequence is then repeated 3 times, until MA is back at starting point. Viewed from above, the manoeuvre will look like a +. Notice hovering is inverted after first and third sequence.
