@v1pro - you can't go wrong with the Cooper Details resin and the rest for this kit. It won't fix that the airfoil for the wings is upside-down, but it will improve the rest for sure.

Tom @ tcinla, agree on the Cooper Details parts. Roy Sutherland makes some nice replacement parts to improve its overall look. I have some Barracuda parts for future builds. For this build I am going to use the drop tanks, lower wing louvers and spinner/propeller. Years ago Roy used to show up at our club back in the 80’s. He made a Hawk Spitfire Mk.22 and a Matchbox Tempest Mk.II into super looking builds. The improvements he made on the Hawk Spitfire was amazing.

I used a thick twisty and cut a piece from it to extend the tail wheel strut.

The Yellow was painted for the propeller's tips.
After the spinner was painted red, a quick gloss coat was then added and after it was dry I high lighted the spinner's recessed details with a pencil and Tamiya's Black Panel Line Accent Color.

You are making the most out of the Hobbycraft kit, my friend @v1pro!
Looking spectacular so far!
