The main disadvantage is poor aerodynamics. The beater acts like a fan and requires a larger motor and battery compared to a drum.

I wonder if this could've solved by making 2 half drums out of say fibre glass and bolting them on to an eggbeater, effectively making it a drum but without using the drum for structural purposes. They might even let you into the drum-off!
