Hi Angus,
I wonder how would everybody feel about the idea of 5Kg +or- 1% ,including fuel and or propulsion batteries.
It would seem like a good way to have a level playing pitch and the FAI 5Kg limit.

Hi B,
I do see where you are coming from, but it would immediately render a lot, perhaps even all IC planes illegal which is not what we want to do. I actually think 5.5kg RTC (ready to compete

) is a great idea.
Maybe, but IC planes have always been weighed with the batteries in. I ask why should an electric plane be exempt from this?
Just because it's for the motor and not the radio gear is a hollow argument under the current rules.
I don't see it as a hollow argument at all and I'm actually not saying electric should be exempt. I'm saying weigh them both ready to fly.
However, given it's the 21st century and we are bound to see further innovation, it sort of makes sense to dispense with the fuel/batteries in/out debate and push for a unified maximum take off weight.
Exactly
Consider placing rules limiting propeller total blade area, diameter, pitch (or all three) should take care of any HP wars no matter the power source.
No need for those extra rules, we already have the noise limit which automatically limits how much power we can use.
