That would be hard to build. Hook up the rotating part to a large outrunner motor,lol. Talk about a wiring nightmare
Rogue, if your really wanting to put 3 edf's on a fighter. Just build a twin, and then throw a 3rd one on top. You could put it in a nacelle on the vert stabilizer like airliners do it. I have a feeling it would need to be quite large though to support the weight of 3 edf's/ motors/ speed controls, as well as a battery big enough to give you more than 30 second flight times. I guess you could always use smaller fans, like 3 55's or something. Or just put 3 of efflux rc metal fans on there. 6kw and like 15lbs of thrust.
