[NSRCA-discussion] Weight History

[Ronald Van Putte]

That is very interesting.

However, I still fail to see the logic that allows glow-powered airplanes to be weighed without fuel, but requires electric-powered airplanes to be weighed with batteries.  

I think we should have a rule that both glow-powered and electric-powered airplanes should be weighed in their takeoff configuration.
