Full carbon frame with sexy color 
, 6 ducted propellors, semi-waterproof, enough room for 4 5A 4s lipo's. maximum prop size is 12".
Props are fully protected, can bump into wall, tree, person, without breaking props or hurting people.
Empty weight is 3,7kg. Current set-up Axi 2804/22 and graupner 11x5" props. Still looking for a better combination though, for increased flight time.
Comments
not too safety ...
You are sacrificing efficiency for safety and robustness. The motor struts are very draggy. With a copter, hang time depends on efficiency. Weight = current = time.
It looks cute.
3.7kg empty weight sounds too heavy; how long it flies (i.e. what its endurance)?
He says that it fits 12" props, and 4x5A 4s batteries, with 6 decent powered motors the 3.7kg, should be a piece of cake to lift.
How does it behave in the wind?
That looks very, very slick. But 3,7kg is a bit much, so I guess that is the downside.
So, are you manufacturing these for sale?
