For the mylar version, I am very impressed by the result, first and most important point is the rigidity of the airframe!
Second point is the weight, at the same stage of assembly my personnal planes (with 6mm) are 6gr lighter, which is pretty close!
Furthermore, there is still some area to milled, nose of the fuselage, Airbrake, gears...2-3g at least!
I let you informed about the assembly as soon as i start it...
Good to see you here Fabien! Weight difference you see is mostly because of thickness of mylar and not such wide opening like you have. We use 0.012mm mylar film, thiner one will not hold printing. As you can see film is WAY stronger than super thin mylar we use until now. So for mass production and regular customers this is much better option. My friend Ignas is assembling milled version of Spies. I move with mylar version build. Here couple pictures:
