I think there's two schools of thought.

One school is trying to replicate the original characteristics of the designs and their power plants, the other school is trying to make the most efficient use of what's allowed within competition rules to maximise their flying performance. I've got my 2M ship for flying pattern but still enjoy digging the old girls out for some sporting around..

I think it's great the variety of electric options exist because it's win-win for everyone.
