One question how did you get the edf unit out of the foam enclosure( engine pod)?
I did not. The EDF Unit on the picture is my spare GWS EDF-55. I used for testing the engine performance. Original duct are still in the plane and I don't need to remove them to replace the motor.
The good thing about the duct in A10 is, that unlike the GWS unit it does not have the center piece (just two tabs for mounting screws). This way I'm going to attached the hub to the motor first, and then insert the motor from the back of the duct. When motor is in place the rotor will be placed from the front. I made my adapters 4.57mm diameter (the hole in the rotor is 4.60mm) so the rotor slides much easier. This extra 0.03mm made a big difference but does not create any slack. So the next time I will need to replace the rotor it will be easy to slide it off by hand (no special tool will be required).
