It should be pretty easy. The EDF 55 version holds to the motor shaft with set screws, so as long as you chose a can that will fit in the EDF unit and has the proper shaft dia, it should be a breeze.

If your thinking about building one I would recommend:

Buy the newer EDF 55 version, not the older versions, as they are extremely underpowered (from reading, not personal experience).

If you want to upgrade the power, do it before building. the nacelles are not going to be disassembly friendly.

Build without the landing gear if you don't mind belly scratch landings.

Reinforce the nacelle mount points with a tube through the fuselage that protrudes enough to also seat into the nacelles.

Reinforce the rear horizontal stab with a rod of some sort. Without reinforcement it is too fragile.

Mount the elevator linkage wire in some type of tubing glued to the fuse. GWS just has it running through a gap in the fuselage and over time is widens and gets really sloppy.


If you plan to upgrade the power, reinforce the wing with something stronger than the provided bamboo rod and consider extending the reinforcement further out the wing.
