THE GRAYWING

EGW-80 EDF

This is the Electric Ducted Fan version of our successful Eclipson EGW-80. Thanks to the use of the EDF motor we could add a very useful landing gear with full suspension, the concept is totally 3d printed and well tested with our model Z, although this LG is just optional, we also provide you the keel to hand launch the model. The plane can be printed with PLA/ PETG but you will get much better performance and a higher thrust to weight ratio if printed with LW-PLA. 

Includes:
-STL files

-G-codes for PLA and LW-PLA
For free:

-Cura profiles
-Model for Real Flight simulator

€27

Features:
-Very low drag design

-FPV camera ready
-Replaceble LG

-Full suspension
