Good ducting is better than hanging in the breeze, and a whole lot prettier.

I was thinking about this the other day. Why don't we change the fuse design to stick the motor out in the breeze? Kind of like a WWI rotary or a foamy.  Seems like we're trying hard to keep the planes identical in design between electrics and fuel for no apparent reasons
 
Also now that huge props and braking are available, will fuselages slim down some?
