MTK,

I have seen many many glow set ups in the world championships on the edge of the 5Kg than in any local competition, and there is no way a YS powered plane can fly FAI with 8oz and be safe to finish schedules with 20mph winds. My Osmose in the WC in Portugal was 4995gr with no fuel, so thinking about the amount of fuels needed is not realistic, my Axiome with top of the line gear is 4890(dual batteries and regulators), it will not pass with a full fuel tank, an Onas will pass as it is a smaller plane, I have it too and in electric, and with batteries(Rhinos) is 4800gr.

The rules are simple and haven argued for years anyway, what you propose is not possible as the helpers in the competition need things as simple as possible or they won't do it, is hard enough to make a simple weight check already.

As Neil said, if the weight rule is eliminated more people will attend, and it is not a WC anyway, there is people that do this for fun still.
