I have been struggling with non-aircraft work, but that is easing (slightly) now, so there will be some more 'racing-car-fighters' very soon - here's what's coming:
Part 331: English Electric Lightning F53 of the Brazilian Air Force.
Part 332: Kawasaki Ki-61 in the BAR Honda livery.
Part 333: Hawker Typhoon in the Gold Leaf Team Lotus livery.
Part 334: FIAT G.55 in the Ferrari livery.
Part 335: North American P-51D Mustang in NASCAR colours.
