sure dont have a size ref, but even in 1/144 it will not be tiny. Small yes but not tiny.
Figure the 1/72 Finemolds kits of the TIE variants borders on tiny, with a cockpit ball the size of my thumb. If you were to reduce that to 1/2 its size, then compare how big the MF is to the size of a TIE...its's still going to be pretty decent size....AND it will fit on your shelf!
I think 1/144 will be a decent size model. HLJ lists it at 34 CM by 19CM. Much more shelf freindly.
