Been contemplating the edf issue, and found a set of plans for a very similar plane, unlabelled so no idea what, been discussing it with a mate. what we might do is build one with 2 edf in it, both in same tube but 1 reversed with a diffuser in between, could be an interesting exercise
Could you explain that a bit more? Two fans pointing at each other in one tube? Where will the air exit?
Got a picture?
