RC EDF housing for a QX motor 70mm EDF. This will fit any 70mm EDF as long as the outer housing is 74mm or less, if its a bit bigger then some sanding may need to be done.
No mounting system is added as it'll be different for everyone but you could easily drill a couple of mounting points into the front end and rear end of the tube.
Exit diameter is 64mm and the thrust tube is approx. 28mm long so it should be efficient and powerful enough for thrust.
