We all know that the 5000g rule was set way before the advent of e-power for our pattern ships.  Technology does continue to improve but we all know there was no thought of ever having an electric powered airplane when that rule was created.  The glow ships easily make 5000g (typically and without great expenditures) and when that rule was made, 5000g would have been considered a ridiculously heavy ship.

It really is OK to change rules to adapt to newer technology.  Technology has ushered in the advent of LiPo powered ships swinging 22" props and contra-rotating drive systems.  We do want to innovate but sometimes in order to grow, our base rules need to be modified.  I say we should consider looking at this simply due to the fact the rule is actually archaic and should be redefined based on current technology.  Again, no way were electric powered planes considered for the current weight limitations.
