>>6665737No 1/350, but the 1/150 Vasa I built seems to be somewhere around that size range. A bit big for my taste overall, though if I ever really feel for a ship for some reason I may do a 1/350 as a one-off.
I've only really been at it for a year and a half here, but I think we're looking at a bit over a dozen kits per year. The smaller ones are pretty quick affairs all said and done. (So perhaps the plan to save space isn't entirely watertight.)
