There's a "How-to" on pop bottle cowls here:

Stuff I normally do to JKA planes (rubber-banded-on wings):

WING

1) Use either 1/8" 'glass rod or 3/16" hardwood dowels for the spars and glued in with ProBond polyurethane glue.

2) Use 1 layer of 1" wide strapping tape in one piece around the entire wing starting and finishing on the top in the center. Always spray a coat of spray adhesive on the foam before taping.

3) Use 2 layers of 2" wide strapping tape over the spars over-lapped by 1/8" to 1/4", top and bottom.

4) 1/4" x 12" hardwood dowel TE from the center on each side. 1/4" sqare balsa TE from the dowel to the tip.

5) Balsa ailerons with torque rods, the bearings glued to the hardwood dowel TE.

6) 1 strip of 2" wide strapping tape laid over 1 strip of 1" wide strapping tape on the LE.

7) Two popsicle sticks imbedded in the bottom of the LE, touching at the center for rubber band crush protection.

8) 6" of the center section 'glassed with 2oz. cloth and epoxy (over the torque rods and strapping tape).

I build the FUSELAGE as described here:

With the following exceptions:
1) Replace the kit's light plywood firewall with 5-ply 1/4" Birch plywood.

2) Slot(s) for the fuel tank cut into the fuselage and the assembled tank tank is glued in place with ProBond polyurethane glue while the fuselage halves are glued together with 5 minute epoxy.

3) The 2mm Coro doublers are glued to the firewall with ProBond polyurethane glue, and the remainder attached with spray adhesive as per the instructions.

4) 1/4" hardwood dowels for rubber band hold downs glued in with ProBond polyurethane glue (the rear dowel positioned high enough to clear the torque rods).

The wing and fuselage also get covered with either TowerKote or EconoKote iron-on covering instead of packing tape. Be sure to spray on a light cote of spray adhesive and let it dry for 1 hour or more before covering, and use a low-temp iron.

I usually use Rustolium gloss colors sprayed onto the covering after scuffing the covering with fine Steel Wool. For the Fw-190, there are several combinations of Rustolium colors that look pretty good:

"Standard Day Fighter" scheme: (AKA- RLM 74/75/76)
Gloss Smoke Gray and Gloss Charcoal Gray over Gloss Harbor Blue undersides.

"Eastern Front" scheme: (AKA- RLM 70/71/76)
Gloss Hunter Green and Gloss Dark Hunter Green over Gloss Harbor Blue.

"Tropical" scheme: (AKA- RLM 79/80/65)
Gloss Sand with spots of Gloss Dark Hunter Green over Gloss Harbor Blue.
