If we go over to 13.6kg here, then its still a full kilo we can spend more on our feathers.

On the other side, if the RFL goes over to the proposed/new limited consumables rule of 600 gram CO2 for feathers up to 2 kg in heavies, then the RFL gets also a new incentive to build pneumatical machines.

Its 600 grams free power...

But its not only the CO2 weight, or the other pressurised gasses.
In the RFL 3000 psi storage tanks are allowed, over here the limit is 1000 psi, so we all use CO2 due the favorable liquid/gas transformation.

The biggest problem is that the RFL has a serious issue with pressure tests and the prototype rule that gives us a legal way to prove our Euro materials.

Also, who cares that a robot would explode in the arena? Its not as if a bunch of spinners dont induce bigger forces.
