Lack of knowledge or Piloting skill?

Recommended Posts

Why is there such a lack of development for quads with EDF’s (Electric Ducted Fans)? I mean can you imagine a quad blade with 4 times 70mm ducts!? What power to play with... I suppose the battery will always be an issue but, there must be some options...

I think that I already have one although not 70mm.

Ducted fans are not more efficient than unducted due to the additional turbulence at the blade edge.  More importantly, the blades are not exposed as much to breakage, which is a major source of revenues for the drone manufacturers as some cannot replace blades (skillset) and other will also break the motors.
