Changing a rule will likely change the planes we fly one more time. As mentioned biplanes would be much more feasable. Will a 2 M biplane fly better than a 2 M monoplane? I don't know. Biplanes never impressed me in the past when flown against a standard pattern plane, but they always had a smaller wingspan. Now they could be the same size if the weight limit was removed.. Each size/or engine limit change has lead to a change in the planes that we fly. Generally getting bigger each time. Would a widebody 2 M pattern plane fly well on a OS Hanno special

Yes it is harder to make the weight limit with an electric but that is becoming easier as battery technology advances. Will we get smaller cells from where we are now? If so then changing the limits for todays equipment will have more profound effect in the future.

I was around when the first people tried 4 cycle 120's instead of a piped 60 when the 4 cycle displacement limit was raised. Interesting but I wouldn't waste my money. Technology improves and YS 120's clearly outperform the best of the piped 60's. Now a rule change made to equalize the 2 technologies allows a swing to the favor of the one that was being helped by the rule change in the first place.

So yes it may be more difficult to make weight with an electric but I say leave it as it is or else a new can of worms will be opened
