I've got an Italeri 1/48 Ar-196A-3 in my stash, and I'm wondering if it needs weights inside the floats, for not to fall on its tail. I found one Japanese blog where the guy (it seems he's the guy whose drawings Arma Hobby have used) put weight inside the floats, it was the 1/72 Sword kit. There's no mention of any weight in the Italeri instructions. I've read that Tamiya's 1/72 Aichi M6A needs 12 grams.
