Hello Again,
To instal tail formers, which also will build up ruder, I cut a large pice of 3mm birch plywood surrounded by by balsa wood, followed by balsa sheet of 1.5mm.
As I mentioned about Flaps& Ailerons, I don't want any horn or linkage to be seen out of fuselage, therefore, Ruder servo is installed and linked to rudder as can be seen in photo,
,

Hello Redtail,
Thanks for your nice words,
It is not my intention to kit this model, But who knows, I lost my job due to Covid-19, :-)), for now I need to make it fly to see if it works,

Jc,
It is not Gorilla, however, its a "Polyurethane Adhesive". Compared to Gorilla, it benefits from lower viscosity, means easier to apply, hence less glue to use & lighter :-)),
Another useful place was to sheeting balsa on wings, where I needed to apply this glue on all ribs and spars, etc, then press balsa sheet, which I used magazines for pressing,

Fuselage will be covered by 2.5mm balsa, sheet and Planking,
As I assume, F-4 would be tail heavy, I will reinforce nose, so I can locate battery and air tank etc, Hoooooppppiiiiinnnnnggggg to avoid lead on nose :-),

Hello guys,
To make nose,







To make nose,
- I made a double round former which are both drilled and pined with 6mm carbon rod, one side glued and the other side free.
- A 10mm hardwood dowel drilled 3mm and glued into a balsa block, to shape the head of nose.
- A 3mm tee nuts installed on small round plywood which is glued to tray,
- Planking followed, gluing balsa little nose to outer round former,
- once planking is completed, opening 3mm socket cap head screw, released the hole nose,

Hello Chic,
It is kind of you,
Honestly, it is more difficult than I was expecting, too many changes in curve, luckily I have many formers to make the shape, :-))
My plan is not to make it as kit, and I can't even suggest it to anyone, it needs to be tested and I hope It will fly nice,
CG would be a challenge with two turbine on rear fuse,

Thanks,
