Always wanted to do an EDF quad but I'm guessing the flight time will be awful. you'd probably want to use outrunners of a lower Kv with high pitch blades and lots of em. if the throttle range is too big it'll make corrections difficult so it will be a bit unstable.

There are no restorative moments on a vehicle of this type. It is by definition unstable and requires stability augmentation. An exponential adjustment on the transmitter may correct for non linear responses of control axis. The flight time is simply related to the battery capacity and current draw. Current draw is dictated by prop loading, which changes during flight. Flight times will vary*.
ANy chance you could do an "Instructable" on the whole project with parts list etc and what controller you are using?? Looks great btw, like to use one at our Hackerspace.
I don't see here the part for the body.
Are you using one of the parts from the parent part?
where do you get blades for it. I notice all yours are ccw.
Looks the goods
looks badass.
is it louder or quieter than ductless fans?
i suggest you print that in clear pla.. it will reflect the enviroment and stealthcloak the copter a bit.

Would you be willing to post a video of it spinning up? I would love to see how it behaves regardless if it flies or not.
