I got this kit as a present over Christmas:
I'm planning to build it in a month or so, and as usual it'll be pretty much OOB for me (even at this scale). However, I'm not completely against the idea of sprucing it up a little if there are some easy upgrades for it out there. I'll be building it wheels up (with a spinning prop) so I don't really need engine details or anything like that.
A quick search on Hannants shows these Hispano cannons, which do look nice! They also have a Decal set which comes with 3 options, all for Jan Zumbach's aircraft. Considering that the box art of the kit shows one of his, but with the wrong code (AB910), I think getting the right decals might not be a bad idea either.
Does anyone else know of any aftermarket stuff for this kit?
