i like any thing that resembles a warplane with a soft spot for 3 aircraft. the F-16, spitfire (who doesn't) and the BP defiant because it is so quirky.
i mainly build 1/72 and 1/48 but i do occasionally venture into 1/32 and 1/35 AFV's and artillery
list of notable finished builds
1/48 airfix Hawker Hurricane (V good kit)
1/48 airfix defiant (another v good kit)
my first a 1/72 airfix spit
1/35 tamiya pz.II
1/72 vulcan (big bird)
148 airfix op Herrick BAe Warrior with men
good builds on way (hopefully):
airfix 1/48 meteor F.8 (korean war)
italari 1/48 IL-2 MADE!!!!!!!!!!
and (maybe, just maybe) the 1/24 airfix Hellcat
airfix 1/76 bofors and tractor
BTW i am thoroughly bitten by 2 bugs. the BM bug and the Modeling Bug
