I was thinking a ducted fan design using heli motors might work.

You'd need some type variable pitched rotors or fixed pitched blades to keep it nice and stable as these can't speed up and slow down.

Hahaha! That's a pitiful amount of thrust! You'll need 40 of those to lift the amount that Irishluck has targeted.:p Go back to the KDE motors I linked at the beginning of this thread. 8 of them gave 137kg of thrust.

Hahaha, I was referring to using a ducted fan design with helicopter motors and some sort of 5-7 blade steep pitch prop.

Ok. I see what you are after now. I thought ducted fan motors were designed to really spin up. Heli motors use gears to swing large, slow rotors. Do you think they would work?

Out of curiosity I looked up more info on heli motors. They are not designed for continuous speed changes. More for constant speed or small speed variations. You're ducted fan idea does give good protection and does help efficiency. Worth pursuing.

That is why I said: "You'd need some type variable pitched rotors or fixed pitched blades to keep it nice and stable as these can't speed up and slow down." hahaha. I was thinking like 4 big ducted fans with heli motors for heavy lifting and big slower changes and 4 propped quadcopter like motors for minor changes for stabilization.

Hey, Neil reminded me of a cool thing that hobbyking did, just to show you the power of these EDFs.
