Changes to the RC Categories

2

For the year 1974, the changes to the RC categories described below will be introduced on a provisional basis. At the end of 1974, the RC Commission will then draw up the final regulations based on the experience gained.


All Swiss championships will be held this year according to these new rules and programs—while the regions themselves can decide whether their championships this year will be held according to the old or the new rules. However, holding a regional qualifier under the old format seems to make little sense, since the pilots who qualify there will then have to fly the new programs at the national competition.


1. Gliding

The Landing

In both gliding categories, the landing takes place within a 45-by-15-meter landing rectangle, which is divided into three 15-meter squares. The pilot receives the highest score (or the highest coefficient) if his model comes to a stop in the last of the three squares. The decisive factor for the target landing is the model’s coming to a complete stop, with the location of the model’s nose being evaluated.

In both categories, the landing is scored as zero if any of the following applies:

  • Breakage or loss of a part
  • A landing where the model lands on its tail
  • Approach over a long side of the rectangle
  • The model overturning

F3B - Hangflug
  • No changes except:
  • Unlocking the pilot's location
  • Conversion of the landing circle to a landing rectangle

F3B - Aerotow Launch
1. High StartK 3
2. Cloverleaf (starting on the left)K 12
3. Left RenversementK 12
4. One loopK 6
5. Rectangular approachK 8
6. Landing (5-second straight approach)
in the last fieldK 10
in the middle fieldK 7
in the first fieldK 5
outside (on the slope axis)K 3

2. Powered Flight

In the powered flight categories (formerly RCM and RCMM), there will no longer be any distinction based on the aircraft type. All functions and features (ailerons, retractable landing gear, landing flaps, adjustable wing geometry) are permitted.

Nevertheless, the commission has retained the division into two categories, primarily to promote the next generation of pilots, but also to offer multi-channel pilots who do not train extensively an opportunity to compete, even as the FA1 category becomes increasingly challenging.


F3A - National (formerly RCM)

Maximum flight time: 8 minutes, including 3 minutes of pre-takeoff preparation

For each flyby in front of the judges, it is recommended to perform the next maneuver, with the exception of the trim flight after takeoff and the landing preparation after the spin. (This is a recommendation.)


Lineup of Characters
1. Start (from a standstill)K 10
2. Two loops performedK 5
3. Inverted flight (approx. 5 sec.)K 10
4. Left rollK 10
5. Two looping maneuversK 10
6. Double ImmelmannK 15
7. Two horizontal rollsK 10
8. Three rollsK 10
9. Rectangular plotK 10
10. Landing
Circle, 15 m diameterK 15
30 m diameterK 10
outsideK 5

F3A - FA1 (formerly RCMM)

Maximum flight time: 10 minutes, including 3 minutes of pre-takeoff preparation. Timing begins exactly 1 minute after the call.

Each pass in front of the judges is also counted as a maneuver here, with the exception of the trim flight after takeoff and the landing preparation after the spin.


Lineup of Characters
1. StartK 10
2. Figure “M”K 15
3. Cuban EightK 10
4. Double ImmelmannK 10
5. Slow RollK 15
6. Three pushed-through loops (from inverted flight)K 10
7. Four-point rollK 15
8. Three towed loopsK 10
9. Eight-point rollK 15
10. Lying eight (1 1/4 loop, pushed + 1 1/4 loop, pulled)K 10
11. Three horizontal rollsK 15
12. CylinderK 15
13. Figure-8 roll (upright figure-8 with 2 half rolls)K 10
14. Three rollsK 10
15. Rectangular LandingK 10
16. Landing
Circle, 15 m diameterK 15
30 m diameterK 10
outsideK 5

Diagram of a 45x15 meter landing rectangle divided into three 15x15 meter squares. It shows the 'Anflugrichtung' (approach direction) with an arrow pointing right and the 'Windrichtung' (wind direction) with an arrow pointing left. Scoring zones are indicated: K 3 for the first square, K 5 for the second, and K 10 for the third. A K 15 zone is also marked for the third square.
