Rules Update
2023
After a long Corona break, we had a total of 6 F3G competitions in 2021 and 2022.
These have shown that we have created an exciting, challenging and interesting new model flight class with F3G. However, it has also been shown that some rules should be improved and formulated more transparently. Once again a big thank you to all the input from the many F3G pilots.
The following rule adjustments regarding F3G are therefore pending for 2023. These have already been approved by the CIAM Technical Committee. During the CIAM Plenary Meeting on April 1, 2023 the final decision will be made if they are applied and included into the F3G Rules 2023-.
800 watts average drive power
The rules that the average power of the drive train may not exceed 800 watts will be deleted without replacement.
Physics and countless test flights have shown that the average power is not decisive for the achieved altitude. It only decides how fast or slow you reach it. In addition, it is relatively difficult to configure the drive train in such a way that the 800 watts can be maintained.
Wing Loading
The formulation that the minimum wing loading refers to the projected wing and tail area has been further specified and updated. The existing wording left room for interpretation. The definition for F3G now follows the established practice of the other model flight classes.
Spinner Nose Radius
Spinner nose radius has been reduced from 7.5mm to 6mm. The background is, that the 7.5mm were taken over from F3B. However, the commercially available spinners used by the F3G pilots have a smaller nose radius.
Logger Connections
The previously prescribed 4mm connections on the logger or battery and current sensor will be moved to the EDIC documentation. It is added that each pilot can use the connections of his choice, but must provide an adapter for the 4mm plug connections for the organizer to check.
Logger Display
The wording of the logger has now also been made more precise. The logger used, must immediately display the parameters required for the competition - engine runtime, energy and take-off altitude - using a built-in or external display. If this is not the case, the flight will be rated with zero points.
Maximum Number of Batteries per Model
The limitation to a maximum of 3 flight batteries per model will be canceled without replacement.
Early Entry Penalty Points for Distance and Speed
The penalty if the pilot enters the course before 40 seconds (after motor start) during distance or speed is reduced to 100 points.
Other Adjustments
There are still a few semantic adjustments where the existing regulations still refer to F3B-E and not F3G.
Final Remark
With these adjustments, the F3G regulations are even more precise and practicable without losing any of the excitement and the challenge for the pilot, model and helper.
We have left the "Provisional" status as it is, which gives us the opportunity to propose further rule adjustments at the end of 2023 if necessary.
