I happen to be working on a 1/48 A-26 as a special project, building a replica of the one used in the 1988 Steven Speilberg film "Always". Great film about fire bomber pilots with some excellent footage of A-26Cs and PBY-5As in flight and on the tarmac.
I started with the Revell kit and had to make a few mods to the fuselage to remove the gun turrets, as this is to be a fire bomber. I also had to modify the nose section to install the glass nose (luckily, most all of the parts to do this were included in the kit) since the kit was for an A-26B with a six-gun nose.
It has proven to be a good challenge so far since the finish is a combination of paint, NMF and custom decals. I can tell it will be well worth the effort once it is completed.
