Uh....it actually says it's exactly the same size and weight as the .91FZ. Basically it's a rebored .91. Where did you get your '20% bigger' info from??
I'm waiting for Central Hobbies to get more stocks of the 1.10FZ, so I can put one on my World Models 1.20 Ultimate Bipe. I was running a .91FZ on it (which I pinched for a pattern model), so I'm banking on the 1.10 being the same size!!
