Cant confirm that.....the more precise things like gears get, the easier you can break it. That simple.....try Matchbox maybe or old Herpas....those gears can roll and you cant break them.
You can simply not compare anything like Herpa, Star Jets etc with Schabak as Schabak just lacks the detail.
And that does definetely not mean that I like Herpa most.... I think Star Jets were pretty nice when it came to detail.
