Trying to build a 5" long range quad.

eCalc says 2204-1800kV motor would give great range, however, when trying to find 2204-1800kV products, it seems they are all made for fixed wings (cannot mount to quads).


Question 1: Anyone know of a decent 2204/2205/2304 @~1800kV motor for 4S quads?
Question 2: Is it reasonable to expect that a quad-motor will have the same efficiency/performance as a fixed-wing-motor, if they have the same size and kV specs?

Thanks in advance
