Hi Carlos. Long time no speak. I hope all is well for you?
I have also just unpacked my Skymaster L-39. Its the blue painted version and wow! I am impressed. I had read some issues on other threads about the single layer gear doors and how difficult it was to hinge them. Mine has been supplied pre hinged as well as being moulded so seem super stiff.
The Paint finish is great and I think looks really stunning. its a little heavier than I anticipated but still well within what feels like an acceptable weight.
I might join you on this thread ( if you dont mind ) as I hope to start building mine this week.
Regards Al
