Looks very good for the first try, Martin @naviatik
Just a bit of modification to be done.

Looks wonderful, my friend @naviatik!

Fitting is not perfect, but it is really close.
Meanwhile, I found good picture of fuel tank installation in Aero Detail No. 17. - it is great publication, definitelly recommended, there is a lot of nice, color, high quality photos, covering all important parts and details of the type.
I am currently off my appartment, but working on extra parts. In few days, when I return, I will place pictures with some progress.

I little re-worked that stuff and added few extra details. I really wanna see it placed in the kit. 🙂

Great design, would love to see it in the kit as well, Martin @naviatik

All parts are printed, painted, placed (except of oxygen bottle). Everything fits quite well, although I will do some minor changes for final version.
It is definitely great improvement when building F6F-3 version with side windows.
I will close the fuselage now and have to finish flaps section + wheel bays + legs + wheels... A lot of work, but I got also a lot of experience and I feel confident enough to finish the job.

Bad news guys... I was just told that correct color of aft fuselage is FS36440... So... I have put everything down and start again.
Not happy about it, but thanks to easy 3D prints reproduction it is not so big deal.
It is just small detour.
I will be back with better result soon. 🙂

Very nice work on this Martin. Having done a couple of these kits, I can assure you that once the fuselage is together no one will ever know what the color of the rear fuselage is.
