Hi
If discussing the future rules is not relevant to the future of F3A in your view then you need to answer the following question for yourself.
What is F3A ??
You will find the answer in the rules that define F3A

.
I am not discussing the 160g of fuel that's used.
I am discussing the unlimited extra amount that can be carried.
What is the point in a weight specification.

The rule has been discussed ad neuseum, Voted on and is what it is. It just keeps going on and on like a broken record by those that disagree with it.
The unlimited extra fuel that IC flyers can carry is a disadvantage. The only reason anyone would carry extra fuel is lazyness or to effect a CG shift via a chicken tank...
The weight rule prevents larger draggier airframes requiring more power from being developed, just like the old 10cc motors did back in the day when the 5kg rule was there but it wasn't a problem.
