If I read the tables correctly the EDF-64 itself weighs some 67g then the motor adds another 57. My motor, fan and duct only weighs 57g.
Its aerodynamics may not be as good but its thrust to weight ratio is about the same.
The aerodynamics of a slow park flyer are pretty poor anyway so weight tends to be the dominant factor hence my lightweight construction.
Some more progress.
The booms fixed and the ailerons cut out and top skins added.
