Rule changes F1Q

From: Dieter Paff

Hello Roger,
it is interesting to note that even though this beautiful class is so new, there`s already a talk of rule changes for F1Q. Some say the models are too big, others say they come too high, other have the opinion that the performance are to high, etc, etc.

Nobody questions the F1C class with heights of 160m, or the F1A class with 130 on launch,  with a much lower sink rate in glide. Get rid of the nonsense of throwing yourself to the ground at full running speed and risking serios injury. F1B models also climb between 120 and 130 m today and have better sink rates as F1Q models as well.

I therefore cannot understand this discussion now about performance limitations of the F1Q models. Why should a rule be made now ? The competition director already has the opportunity to adjust the amount of energy according to the weather and field conditions, in coordination with the participants.
Much more important will be a technical device  to measure the correct programmed Joule amount !!
Let`s fly a few European and World Championships first and see what developments will bring the future. Then we my correct  the rules if necessary.
My Best Regards

Personally, I already fly with 2 Joules/gram with occasional small drops in strong downdrafts. Even with 2 J/gr, about 50% of Q fliers are likely to reach the flyoffs – not different than say B or C. With 3 J/gr probably 65-70% would likely make it.

Of course, the Germans could submit a 2 J/gr proposal to CIAM, making it official at the ’25 World Championship. However, it probably has a better chance of approval after the first Q world championship, in my opinion.
