Well there was the old AEF one although it was designed for the old and terribly inaccurate Dragon kit so it's very unlikely to fit the Trumpeter version which is the sensible option now. However, I've never seen an aftermarket set for it, although I have started drawing up the major components. Unfortunately I don't have one in my garage though, which means that it is a prolonged business, particularly as I keep running into other distractions.
